    Notes: Methacryloyl chloride was polymerized in a number of solvents, and the polyacid chloride was converted into the methyl ester. The yield and viscometric molecular weight are given for each sample, whereas the osmometric molecular weight is given for selected samples. The choice of solvent controls the degree of polymerization between the limits of 500 and 8,800. Polymer yields were about 20% and the degree of polymerization was 1500 when dioxane was used as a solvent, whereas the yield increased to 45% and the DP was very high when such solvents as cyclohexane and n-hexane were used. Polymerization in solvent mixtures gave intermediate molecular weight values. Infrared analysis showed the presence of anhydride.

    Notes: A water immiscible liquid is encapsulated in a thin skin of an insoluble copolymer by dissolving a difunctional acid chloride in said liquid and spraying the solution in fine droplets into a dilute aqueous solution of excess glycol or diamine. The polymer, which is not hygroscopic, forms as an insoluble film on the periphery of each drop. The microcapsules may be separated from the aqueous phase and dried without coalescing. Dyes, pigments, stabilizers, and other materials may be incorporated within the capsules.

    Notes: The movement of coloured markers (polydimethyl siloxane and low density polythene) placed near the die entry before extrusion or injected through the side of the die during extrusion has been measured both above and below the onset of instability. During stable flow the observed velocity distributions are similar to those predicted by assuming that polymer at the die wall is stationary, but when melt fracture occurs there is movement at the wall. The possibility of a stick-slip mechanism being responsible for unstable flow is examined and evidence in support of this hypothesis is presented. Available evidence suggests that for a given molecular weight, the critical shear stress increases with the polarity of the polymer, and the material of which the die is made has been found to affect the instability.

    Notes: The effect of polymers with conjugated bonds, namely polyphenylvinylene, phenylacetylenep-diethinylbenzene copolymer and thermally dehydrochlorinated polyvinylchloride, upon the stability of polyvinylchloride suspensions has been investigated. It has been shown that polymers with conjugated double bonds are efficient inhibitors of the thermal dehydrochlorination of polyvinylchloride. The most active inhibitor, polyphenylvinylene, is not light stabilized.

    Anomalous flow behavior of high density polyethylene melts (1963)

    Notes: Attempts to operate plastic processing equipment at higher production rates is often accompanied by erratic flow behavior of the polymer melts. In order to study this problem, a constant-rate, capillary rheometer was used to study the melt flow over a wide range of shear rates. These data demonstrate that many high-density polyethylenes exhibit a discontinuous shear-stress shear-rate curve; that is, under certain conditions the observed load oscillates “between two values differing by about 15%”. This region of unstable melt flow is not necessarily allied with melt fracture although it is dependent on molecular weight and melt temperature. Unstable melt flow occurs at lower shear rates with a decrease in the melt index (increase in molecular weight) or melt temperature.

    Some bonding characteristics of nitrile-phenolic liquid adhesives (1963)

    Notes: It is demonstrated that the bonding characteristics of commercial liquid adhesive primers made from nitrile rubbers and phenol-formaldehyde polymers, cured by means of hexamethylenetetramine can be quite sensitive to the presence of small amounts of excess water and ammonia. The added water partially decomposes the hexamethylenetetramine to formaldehyde and ammonia, the concentration of the latter thus increasing to such a point as to promote a lower temperature curing of the phenolic resin. Restoration of the original adhesive properties can be attained by the addition of reagents which remove either the water or the ammonia, or both, from the adhesive. Examples of such reagents are certain organic acids, anhydrides and peroxides. The addition of these reagents has been found to reactivate and increase greatly the useful lives of nitrile-phenolic liquid adhesive primers containing hexamethylenetetramine.

    Notes: Monomers for which the necessary information was obtained for comparison included the following: styrene, α-methylstyrene, cis and trans-propenylbenzene, allylbenzene, m-methylstyrene, p-methylstyrene, o-, m-, and p-chlorostyrene, 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, and 3,5-dichlorostyrene, p-ethylstyrene, and p-tert-butylstyrene. In both free radical and ionic copolymerizations involving similar monomers, plots of the logarithms of the relative reactivities of several substituted styrenes toward the styrene and methyl methacrylate radicals versus the differences existing between the exaltations of substituted styrenes and the exaltation of styrene were strikingly similar to those in which Hammett's sigma values for the styrene substituents were plotted against the relative reactivities of the substituted styrenes.

    Notes: The size of the crystallites in nylon 66, polytetrafluoroethylene, and polyethylene correlates with the degree of crystallinity. This supports the suggestion that the amorphous content of partially crystallized polymers can be attributed to chain folds and other regions directly related to the crystalline structure, at least down to a level of 40-60% crystallinity. In all cases, the term “percent crystallinity” is a useful unifying concept expressing the over-all degree of order including mesomorphic structures, the relative amounts of ordered and disordered material, and the quality of the ordered regions.

    Notes: A determination of the performance indices of ablative plastics is indeed a formidable task because of the severity of the high-temperature test environment, nonstandard test methods, limitations of available evaluation facilities and the complex interrelationship between materials performance and environmental parameters. In spite of these difficulties, considerable progress has been made in establishing new test methods for evaluating very high-temperature (ablative) plastics. This article describes the test facilities and measurement techniques available for obtaining research and design data on ablative plastics.

    Notes: Films of polytetrafluoroethylene, irradiated in halogen atmospheres, decrease in ultimate tensile strength and elongation at break almost as rapidly as in oxygen. The rate of degradation is approximately independent of chlorine pressure down to about 1 mm Hg. The phenomena can be explained semi-quantitatively in terms of first order, cage reactions of scission, recombination, and reaction with chlorine, complicated by diffusion at low pressures. However, all reaction and diffusion parameters must shift with gradual increase of crystallinity.For a given decrease of elongation at break, polytetrafluoroethylene irradiated in a vacuum retains a relatively higher ultimate tensile strength. In the copolymer of tetrafluoroethylene and hexafluoropropylene, the changes in ultimate tensile strength and elongation at break are much slower under all conditions. Both polytetrafluoroethylene and the copolymer retain appreciable tensile strength but little elongation up to a dose of 2 x 108r.

    Notes: This study summarizes the flow behavior of concentrated and melt systems of linear amorphous polymer. For low molecular weight polymer, viscosity increases regularly with a lower power dependence on molecular weight. This dependence decreases towards first power with increasing temperature but is independent of shear, with viscosities being constant up to the highest attainable steady state stresses, about 106 dynes/cm2. At a higher molecular weight, 2,000-40,000, depending on polymer type, the viscosity dependence on molecular weight changes abruptly to a high power which is generally about 3.4. Above the transition, this high power function is independent of temperature but depends markedly on shear. Non-Newtonian flow sets in abruptly and predictably above the transitional molecular weight.

    Notes: A simplified creep apparatus was used to evaluate the creep and recovery of polyethylene and polypropylene. The creep resistance of polypropylene containing as much as 9% n-heptane (boiling) soluble material is superior to that of linear polyethylene. The lower the boiling n-heptane soluble content, the better the resistance to creep. The creep resistance of polypropylene is also improved by annealing.

    Notes: The diameter increase of a molten thermoplastic extrudate is discussed in terms of the viscoelasticity of the resin. A swelling index, the ratio of the extrudate diameter to the orifice diameter, is defined. It was observed that swelling data taken at different temperatures can be correlated with stress in the die. An unexpected influence on the swelling for polyethylenes is the length of the die where short dies show larger swelling than long dies. Some suggestions for reducing swelling tendencies are made based on a simple model for flow in a capillary.

    Notes: Based on the simplified, flat-plate, isothermal, Newtonian flow model of the screw pump, an expression for pressure as a function of time at a fixed point on the extruder barrel has been derived. This expression predicts a periodic saw tooth pressure cycle under most flow conditions. It also establishes the flow conditions under which an inversion of the saw tooth cycle will occur. Pressure transducer data, in conjunction with extrusion rate data, can be used to calculate the average fluid viscosity in a region near the transducer.

    Notes: Basic considerations are presented for the formation of three-dimensional or “polymer” units from the conglomeration of freely moving reactive molecules. The resulting “heterophase” conditions are shown between these swelling units and the not-polymerized fluid matter. Systematic variations of the ratio of the phases and changes in material are discussed.

    Notes: The melt extrusion of a commercial polypropylene resin was studied with a screw extruder and a series of capillary dies of length:radius ratios varying from 0 to 65. Three temperatures and the range of shear rates encountered in industrial processing were covered. The temperature dependence of the apparent melt viscosity of polypropylene was intermediate between linear and branched polyethylene. Extrapolated zero shear activation energy for viscous flow was 9 ± 1 Kcal/mole. Shear dependence of the apparent viscosity of polypropylene melt was greater than for branched polyethylene in turn, greater for linear.

    Notes: The sorption of nitrogen vapors on polyethylene, polytetrafluoroethylene, saran, polyvinylalcohol, polyvinylacetate, polystyrene, cellulose and ethylcellulose at the nitrogen boiling point has been investigated. It has been shown that polyethylene, polytetrafluoroethylene, saran, polyvinylalcohol and polyvinylacetate are non-porous sorbents with dense packing of the macromolecules. It has been shown that the specific surface area of cellulose, ethylcellulose and the total pore volume of polystyrene calculated from nitrogen vapor sorption is less than the corresponding value determined from the sorption of organic substances. Nitrogen vapor sorption at the nitrogen boiling point cannot be used for estimating the porosity of loosely packed polymers.

The relationships between chlorine content, molecular weight, glass transition temperature and a number of mechanical and rheological properties are described. Data are presented on the effect of blends of various resins in this series on glass transition phenomena. The stability of the resins to dehydrochlorination is discussed.

    Notes: Mixing of viscous fluids in an annular channel is analyzed theoretically. Four basic mixing patterns are described which can be generated by altering the relative rotational velocities of the annular boundaries. Only one aspect of the mixing problem is isolated, i.e., reduction in striation thickness. Problems of front to back mixing to iron out variations of feed stream composition and mixing of solid particles are not considered. The theory was verified experimentally using molten polystyrene.

    Notes: The permeability of films to O2, CO2, and H2O vapor is reduced by drawing processes. The permeability data are compatible with the hypothesis that crystallinity reduces permeability because of (1) a decrease in the volume fraction of penetrable amorphous polymer; (2) a lengthening of the diffusion path by impenetrable barriers, presumably crystallites; and (3) a reduction in segmental motion within the amorphous volume. Analysis of the effect of molecular diameter on diffusion rate shows that the segmental motion within amorphous polypropylene regions is less than that in natural rubber.

    Notes: This investigation studies the behavior of several cylindrical specimens of a Buna-N elastomer subjected to compression impact by a finite mass. Initial strain rates fall in the range between 40/sec and 400/sec, with maximum nominal strains up to 0.4. It is shown that values of nominal stress, true and nominal strain, energy dissipation and impact duration can be correlated with elastomer geometry and initial kinetic energy by means of two parameters derived from an analysis of a linear viscoelastic model. Other sources of variability of elastomer behavior are discussed.

    Notes: The application of a free vibration technique to the study of the cross-linking of an epoxy resin by an amine is demonstrated. Curing curves are presented showing the changes in dynamic mechanical flexural modulus and damping during reaction. At room temperature, the glass transition point is reached after a conversion of about 65% of the epoxide groups. Comparisons of the dynamic mechanical and infrared curing curves indicate a lowering of the reaction rate after this point is reached. Finally, an activation energy for the epoxy-amine cross-linking reaction is calculated.

    Notes: The polymer was prepared by pyrolyzing the sodium salt of 3,5,7,8,-tetrachloroperfluoro-octanoic acid and subsequent dechlorination of the resulting heptene with activated zinc. The heptadiene was separated from other dechlorination products and brought to a high degree of purity through use of vapor phase chromatography and polymerized in bulk utilizing gamma rays at room temperature, 100°C and 150°C, and utilizing ultraviolet light at 150°C. The properties of these brittle and glossy polymers were determined. Also the purified 4-chloroperfluoroheptadiene-1,6 was telomerized with dibromodifluoromethane yielding a cycle, clear, colorless, liquid telomer.

    Notes: The influence of bulk physical properties on the bond strength of an adhesive was studied. A conventional epoxy resin when cured with various mixtures of phthalic acid and anhydride exhibits maximum bond strength when the curing agent is 75% acid and 25% anhydride. This effect is explained on the basis of physical properties of the unfilled resin systems. Most significant of these were the heat distortion temperature and the compressive break and yield strengths.

    Notes: Seventeen different samples of styrene polymers and copolymers were examined in a capillary extrusion rheometer over broad ranges of temperatures and shears. They were injection molded in a spiral mold over the same temperature range. If viscosities at constant shear stress are obtained from the rheometric data, they cannot be correlated with spiral flow results. However, if viscosities are calculated at a proper “high” shear rate, capillary data correlate will with spiral flow results at all temperatures and for all materials.

    Notes: The problems of unsteady-state heat transfer associated with the melting and cooling of crystalline plastics such as polyacetals, high density polyethylene and polypropylene, are complex because of the latent heat of fusion that must be dealt with in problems where the temperature range being considered extends across the melting range. In the case of polyacetals, the use of a computer is shown in the literature to provide solutions to those problems. For many molding shops, such aids are not available. Numerical methods for the solution of such problems have been investigated, and their results are compared with those obtained using a computer and published for polyacetals. Cooling curves derived from numerical calculations, for slabs and rods made from high density polyethylene and polypropylene, are presented. Applications of the method are indicated.

    Notes: Dilatometric measurements show that both isotactic and atactic polypropylenes have two distinct glass transition temperatures. Because of the two transitions, three values for the cubical coefficient of thermal expansion are necessary to accurately define the volume expansion of polypropylene from -80° to +90°C. A method is outlined for calculating the content of amorphous atactic, amorphous isotactic, and crystalline isotactic polymer in a given polypropylene sample.

    Notes: The chemical changes taking place in polyethylene in the process of flame spraying have been investigated qualitatively and quantitatively by a spectroscopic method. It has been shown that oxidation occurs during the process with the formation of acidic, ketonic, ester carbonyls, associated hydroxyls and -C-O- bonds. The degree of unsaturation also increases due to growth in the number of vinyl and trans-vinylene groups. A small increase in the number of CH3 groups is also observed.

    Notes: The radiation-induced polymerization of n-tetradecafluoroheptene-1 was investigated at pressures of 8100, 11,900 and 17,100 atmospheres and temperatures between 90 and 267°C. The data are interpreted in terms of a free radical mechanism and the polymer has a low ceiling temperature. As temperature is increased, the depropagation step becomes important and reduces the rate of polymerization. Under some conditions transfer seems to be a significant part of the mechanism. Several radiation-induced polymerizations at high pressure were carried out with 1,1,2-trifluorovinylphenyl ether as well as one with 1,2,3,4,5-pentafluorophenyl 1,1,2-trifluorovinyl ether. The results suggest that transfer limits the molecular weight of the polymers.

    Notes: The effect of resin mass on the degree of crosslinking during the initial polymerization of three typical polymer compounds was determined by electrical resistivity techniques. Activation energies for the electrical conduction process (Ec) were calculated and used as an index of the extent of additional crosslinking occurring during sixteen months of storage. Test data show continued polymerization at slow rates for periods of time ranging from three days to over sixteen months before the polymerization process is completed. The final degree of crosslinking is shown to be dependent on the extent of initial crosslinking.

    Notes: Analysis in liquid or solid state and in various conditions of cure, have been developed. The analysis is carried out by spectroscopy in the near-infrared region. Epoxy values are determined preferably at 2.205 microns, or else at 1.159 microns. The required path length in the specimen is between 1 and 10 mm, solid resins were examined either in disposable glass cells or in the form of cast sheet. A direct method of evaluation is used when the path length is precisely known, a relative method based on internal calibration when this is not the case. Similarly, a near-infrared method for the determination of hydroxyl groups in epoxy resins was developed. The use of the isosbestic principle led to an accurate method for the determination of hydroxy values in uncured epoxy resins.

    Notes: An attempt has been made to categorize the various materials which have been utilized in polyester compositions to impart or enhance the fire-retardancy of these compositions. Examples of halogen-containing and phosphorus-containing compounds are classified according to where they may be thought to occur in the complex chemical structures which are polyesters. The classifications are basically designed to take advantage of the known chemical reactions which lead to polyesters; the fire-retardant component may be incorporated into the final composition in the diacid, diol, crosslinking agent or may be merely mechanically added as a diluent.

    Notes: Variations were made in the concentration of tin and amine catalysts used in a typical one-short polyether flexible foam system. Differences in foaming characteristics and foam stability were correlated with the relative rates of the chemical reactions which are believed to occur during the foaming process. Physical properties measured on the samples showed in many cases a dependence on the balance between the tin and amine catalysts.

    Notes: The relationships between crystallinity and physical and technological properties of high polymers are examined. In addition, the relationships between structure and crystallinity are discussed and polymers consisting of asymmetric monomeric units are examined in particular. In correspondence with the different possible configurational successions, different conformational characteristics (chain structures) and different physical properties are observed. Polytactic polymers are taken into consideration for the most part. With regard to copolymers, various types of crystalline polymers, in particular those which due to isomorphism of monomeric units are crystalline for any composition, and new classes of alternating copolymers are described.

    Notes: To date, quantitative stereochemical data are available for a few polymers only. A convenient and graphic representation of this data has been developed. Analysis of this data yields two parameters characterizing a polymer, one representing the tacticity and the other representing the nature of the tactic sequence distribution. The statistical parameters obtained may be related to the polymerization conditions and, hence, to the mechanism of stereoregulation. Furthermore they may be related to a number of physical properties, such as melting point, equilibrium crystallinity, and melting curve. Thus, the proper analysis of the NMR data supplies a link between polymerization conditions and the properties of the resulting polymer.

    Notes: 1,2,2,-Trifluorovinyl phenyl ether and 2,3,4,5,6,-pentafluorophenyl 1,2,2-trifluorovinyl ethers have been prepared, and the nucleophilic reactions of the phenoxide and 2,3,4,5-pentafluorophenoxide salts with tetrafluoroethylene have been investigated. In general, it is some-what difficult to control the reaction so as to produce the desired olefinic monomer. Under truly anhydrous conditions and when other sources of active protons are avoided, the olefin is the chief product if excess tetrafluoroethylene is used. The monomer produced is very reactive with phenoxide ions, and the diphenoxyolefins are the chief secondary products. Both monomers failed to polymerize under normal, free radical conditions. With boron trifluoride an oily material was obtained from the trifluorovinyl phenyl ether. High pressure and gamma rays converted both monomers into polymers.

    Notes: These compounds were synthesized by starting with the addition of the Grignard reagent of bromopentafluorobenzene to trifluoroacetaldehyde and chlorodifluoroacetaldehyde, respectively. The new alcohols, 2,3,4,5,6-pentafluoro-α-(trifluoromethyl) benzyl alcohol and 2,3,4,5,6-pentafluoro-α-(chlorodifluoromethyl) benzyl alcohol, are formed in good yield and undergo smooth conversion to (1,2,2,2-tetrafluoroethyl) perfluorobenzene and (2-chloro-1,2,2-trifluoroethyl) perfluorobenzene, respectively, in excellent yield when treated with sulfur tetrafluoride using n-pentane as diluent. The major pyrolysis product was identified as (2,2-difluorovinyl) perfluorobenzene (α-hydroheptafluorostyrene) and the minor one as perfluorostyrene. Perfluorostyrene was also synthesized in excellent yield by bromination of (1,2,2,2-tetrafluoroethyl) perfluorobenzene and subsequent pyrolysis of the brominated derivative. The dehydrochlorination of (2-chloro-1,2,2-trifluoroethyl) perfluorobenzene provided another good synthesis of perfluorostyrene.

    Notes: A method of predicting the critical pressures of multicomponent hydrocarbon mixtures of known composition has been developed. These mixtures include ternary, quaternary, and quinary systems consisting of normal and isoparaffins, olefins, acetylenes, naphthenes, and aromatics. The method, based upon the mole fraction of the low-boiling component in the mixture, graphically presents the ratio of the actual critical pressure to the pseudocritical pressure as a function of a boiling parameter. For mixtures of more than two components the pseudocritical pressure is based on the critical pressure of the pure low-boiling component and on the actual critical pressure of the mixture consisting of all the remaining higher-boiling components. From an analysis of twenty-seven binary systems (139 compositions) the average deviation of calculated values from reported values is 1.27%. For thirty-four mixtures containing from three to seven components the average deviation is 1.64%.Based upon a similar approach graphical relationships are presented for the estimation of the critical molar density of binary hydrocarbon mixtures of known composition, which also may contain normal and isoparaffins, olefins, nuphthenes, and aromatics. The same boiling point parameter is used to correlate the ratio of the critical density to the reciprocal of the molar average critical volume for nonmethane systems and the product of the critical pressure and the critical volume for methane systems. From an analysis of fifteen binary systems (eighty compositions) the average deviation of calculated values form reported values is 1.54%.

    Notes: Simultaneous mass, heat, and momentum transfer was experimentally investigated for the flow of air through packed and distended beds of spheres saturated with water. The porous spheres were approximately ⅝ in. in diameter. The void fraction of the packed bed was ∊ = 0.416, and the distended beds, whose spheres were positioned in a body-centered cubic arrangement, had respective void fractions of ∊ = 0.576 and 0.778. The distended beds were formed by separating the spheres and connecting them with short lengths of fine rigid wire.Similar relationships for the packed and the distended fixed beds were obtained when the transfer factors were related to the modified Reynolds number. The relationship obtained for mass transfer in packed and distended beds was found to apply to data reported for fluidized beds of spheres.Pressure drop measurements were made which were not exacting but which indicate that the Ergun relationship for packed beds can be used to relate the friction factor to the modified Reynolds number for both the packed and distended beds investigated.

    Notes: Pressure drop measurements were made across packed and distended beds having five layers of smooth plastic spheres, 1.23 in. in diamter, arranged in cubic, body-centered cubic, and face-centered cubic orientations of void fractions varying from 0.354 to 0.882. The distended beds were prepared by separating the spheres with permanently attached short lengths of fine rigid wire. Friction factors were calculated from the overall pressure drop measurements with the Ergun equation and were plotted against the corresponding modified Reynolds number which ranged from 2,550 to 64,900. A single relationship resulted for both types of beds which is independent of the geometric orientation and void fraction of the spheres of the bed.To eliminate entrance and exit effects of the air flowing through the bed pressure drop measurements were also made across the middle layer of each distended bed. Again a single relationship between the corresponding friction factors and modified Reynolds number was obtained which is independent of the geometric orientation and void fraction of the bed.From the two relationships between friction factors and modified Reynolds number the ratio Pk/fk for a packed or distended bed having five layers of spheres is 1.13. This ratio should decrease with increasing number of layers of spheres and approach the limiting value of 1 when the number of layers becomes very large.

    Notes: An elution gas that might be either a single component or a binary mixture, but which in any case was appreciably soluble in the fixed liquid phase on the column matrix material, was used to form a multicomponent liquid phase within the chromatographic column. Vapor-liquid equilibrium was studied both with the solute of interest at essentially infinite dilution conditions and with the solute present at some finite concentration in both phases. From the elution data vapor-liquid equilibrium ratios, or K values, were calculated by expressions relating the solute retention volume to the solute K value in the vapor-liquid system maintained within the chromatographic column.Data were taken for the solutes ethane, propane, and n-butane at infinite dilution in the methane-n-decane system at 160°, 70°, 40°, 0°, and -20°F from 20 to 2,000 lb./sq. in.; for propane at infinite dilution in methane-n-hexadecane at 70°F and 20 to 200 lb./sq. in.; and propane in the system methane-propane-n-decane at 40°F from 20 to 460 lb./sq. in. The univariant gas-liquid-solid locus was experimentally determined for the methane-n-decane binary system.The chromatographically determined K values for n-butane at infinite dilution in methane-n-decane were compared with published static equilibrium values and found to be in substantial agreement. Activity coefficients calculated from the data for all the solute isotherms were compared at atmospheric pressure with the results of the Brönsted and Koefoed relation for estimating activity coefficients of hydrocarbons, and close agreement was again found.

    Notes: The present paper concerns the mechanism of mass transfer accompanied by a first-order irreversible chemical reaction between two phases. Based on the film-penetration concept a general mathematical model to describe the physico-chemical behavior at the interface has been formulated. Mass transfer mechanism may be analyzed and evaluated in terms of the dimensionless groups appearing in the derived equations.For limiting conditions the derived general equations can be reduced to those based on the simple postulations such as the film theory, the penetration theory, and the surface renewal theory. For nonlimiting cases the film-penetration concept provides information which cannot be obtained by either the film theory or the surface renewal theory alone.Experimental results appearing in literature show that the physical mass transfer coefficient is proportional to the molecular diffusivity to the v-th power and that v varies widely between 0.15 and 1.0. The film-penetration concept theoretically predicts this v-variation, whereas, in accordance with the film theory or the surface renewal theory, v has to be a certain fixed value.It is shown that if an accurate physical mass transfer coefficient is available, the film-penetration concept, the film theory, and the surface renewal theory all predict practically the same effect of chemical reaction on the mass transfer rate. However if the chemical mass transfer coefficient is to be predicted without an accurate physical transfer coefficient, the choice of the theory or the mechanism may become important.

    Notes: When drops in a two-liquid phase chemical reactor are able to mix with one another by coalescences and redispersions, any spread of concentration among the drops tends to be averaged out. This phenomenon can affect average reaction rate and selectivity in non first-order reactions or mass transfer rate controlled reactions in the dispersed phase. It was found that for mass transfer rate controlled reactions, or the equivalent zero-order reaction, quite large dispersed phase mixing rates are required to bring conversions close to the level obtained with complete mixing.

    Notes: The rate of permeation of hydrogen through a highly purified iron (Ferrovac E) was measured over a pressure range of 1/30 to 300 atm. and a temperature range of 126° to 693°C. The effect of cold working of the annealed metal and of hydrogen purity were also studied. Permeability, diffusivity, and solubility were obtained from the data. Permeation rate was linear with square root of fugacity rather than pressure. No difference in φ or D between the annealed and cold worked tube was observed. Log D vs. 1/T was linear over the whole range of temperature, in disagreement with recent work showing a break in the plot at about 400°C. The calculated activation energy was lower than values reported in the literature. Solubility agreed well with most previous work and did not show the break in the solubility vs. temperature curve found by some recent investigators. No ageing effect was observed nor any difference between the two grades of hydrogen. All the evidence shows that diffusion through the metal is the controlling rate process in this case.

    Two-phase critical flow of steam-water mixtures (1963)

    Notes: Critical flow of two-phase steam-water mixtures in annuli has been studied, with a cylindrical test section 0.574 in. in diameter with an axially centered rod, 0.137 or 0.375 in. O.D., as a pressure probe. Pressure taps on the wall and the center rod permitted an accurate determination of the pressure profile over the entire length of the section, and, in cases where a movable probe was used, a short distance into the downstream exhaust chamber. Results were correlated by plotting the ratio of the observed critical mass velocity to the theoretical critical mass velocity for homogeneous flow as a function of quality.Exit pressures were found to be lower than most values previously reported. The ratio GO/GTh was found to be independent of the probe diameter, the manner of upstream steam-water mixing, and, for test sections greater than 9 in. in length, the test section length. Since probe diameter had no observable effect on GO/GTH, the correlation may be applicable to full bore pipes near 1/2 in. in diameter. In the range of qualities from 2 to 15% the critical GO/GTH ratio was depressed with increasing exit (throat) pressure, but at other qualities no pressure dependency was noted. The effect of changing the downstream exhaust chamber pressure was found to influence the exit pressure but to have little effect on the observed critical mass velocity. Addition of surface active agents to the steam-water mixture did not affect the mass velocity but did result in increased exit pressure.

    Notes: Measurements of the fluctuations in the mass transfer rate to small circular electrodes mounted flush with a pipe wall are used to study the unsteady nature of the viscous sublayer. These fluctuations in the mass transfer rate reflect flow fluctuations at y+ ca 0.5. From these measurements it is concluded that the flow disturbances are elongated in the direction of flow and are characterized by a time scale equal to the diameter of the pipe divided by the bulk average velocity. An attempt is made to relate the mass transfer fluctuations to the fluctuation in velocity gradient at the wall. It is concluded that the ratio of the root-mean-square fluctuating velocity gradient at the wall to the average velocity gradient at the wall is at least 0.11.

    Notes: Microorganisms undergo a cycle of maturation during their life-span in a proliferating culture. This gives rise to a distribution of degrees of cellular maturation in the culture. The gross rate of any metabolic process carried on by the culture is therefore an average over all degrees of maturation present.Equations embodying the life-cycle concept are developed for cultures of organisms which proliferate by binary fission and do not form spores. The equations are solved for the age distribution in the special case of a continuous, steady state fermentation. Expressions for calculating gross metabolic rates and cell size distributions are derived. Finally, the stability of the steady state fermentor is discussed.

    Notes: The isothermal effects of pressure and composition on the mixture and partial enthalpy differences of the methane-propane binary were derived from PVTy data. A graphical and numerical technique was used to derive the enthalpy differences from 100° to 460°F. and 200 to 2,000 lb./sq. in. abs. for the complete composition range of the binary.The isothermal effects of pressure and composition on the mixture enthalpy data of the methane-propane binary were also calculated with the Benedict-Webb-Rubin and the Redlich-Kwong equations of state. The results of the three methods of calculation are compared. The comparison showed that the two-constant Redlich-Kwong equation of state is as good as the eight-constant Benedict equation of state in the superheated vapor region.The data derived in this work were combined with other methane binary enthalpy data from the literature to construct a general correlation of the effect of pressure and composition on the enthalpy of methane-light hydrocarbon binaries. The correlating parameters are the pseudo reduced temperature and pressure and a mole-average acentric factor.

    Notes: There are certain semiempirical equations for estimating heat transfer coefficients for liquid metals flowing through regular shapes. These contain the factor ψ, which is the average, effective value of the ratio of the eddy diffusivity of heat transfer to that for momentum transfer. The main problem in liquid metal heat transfer has been to evaluate this quantity.

    Effect of carbon monoxide in causing nonuniform gasification of graphite by carbon dioxide (1963)

    Notes: Existing theories on the effect of mass transport on the rate (uniformity) of chemical reaction within a porous solid assume that the reaction is of integer order. However the carbon-carbon-dioxide reaction has the kinetic rate form, rate = k1pCO2/(1 + k2pCO + k3pCO2). For conditions where the retarding effect of carbon monoxide is very pronounced, the buildup of small concentrations of carbon monoxide within the porous graphite can lead to appreciable nonuniformity of gasification. Thus the criteria normally used to predict uniformity of gasification break down. A numerical integration of the combined differential equation of mass transport and chemical reaction has been performed, with rate constants for the carbon-carbon dioxide reaction taken from the literature. The results indicate that extreme nonuniformity of reaction can exist even when the change in carbon dioxide concentration from the exterior of the sample to the interior is small. The results are similar to experimental determinations of non-uniformity of gasification, obtained by determining the porosity of reacted graphite samples as a function of depth from the reacting face. Experimentally nonuniformity of reaction was observed for gasification rates a hundredfold lower than the usual Thiele criteria would predict, probably because of carbon monoxide inhibition.

Data were obtained for fine particles for which pore-diffusion resistances were negligible, for large particles of silica catalysts containing only micropores, and for alumina pellets containing both micro- and macropores. From these data experimental effectiveness factors were evaluated.Theoretical effectiveness factors predicted by using a previous theory (7) agreed well with the experimental results. The application of the theory requires pore-geometry data. The measurement of these data and their use in predicting diffusion resistances are illustrated by experimental data and calculations for the several catalysts. It is shown that a satisfactory method of predicting the significance of diffusion within porous catalysts requires information on the pore volume and pore sizes.

    Notes: A solution is presented for the temperature distribution in a fluid flowing in an eccentric annulus formed with circular cyclinders under the assumption of slug flow. The flow is assumed to be fully developed thermally with constant thermophysical properties. The outer surface is assumed to be adiabatic and the inner surface temperature is assumed to be independent of circumferential position. General expressions and numerical results for a typical set of conditions are presented for the quantities, local heat flux, local heat transfer coefficient, adiabatic surface temperature distribution, and average Nusselt number. The application of the present results to the prediction of turbulent heat transfer to liquid metals is indicated, and a comparison with other liquid metal heat transfer analyses is presented.

    Optimum effectiveness factors for porous catalysts (1963)

    Notes: In the manufacture of catalyst pellets from particles of powder, for example alumina, one of the parameters is pellet density. The opposing effects of density on surface available for reaction and on pore diffusion result in a specific pellet density for maximum reaction rate per unit volume of reactor. The method for predicting the optimum density and rate is presented for a first-order reaction. The data required are pore volumes and pore-size distributions as a function of density, as well as kinetic measurements. Such data are available for the ortho-para hydrogen reaction using a nickel oxide-on-alumina catalyst. Using this system as an illustration, it can be seen that the optimum effectiveness factors are less than unity and range from about 0.68 for 1/8-in. diam. spherical catalyst pellets to 0.29 for 1-in. pellets. Corresponding optimum densities are from about 1.3 to 0.6 g./ccThe results demonstrate the possibility of a tailor-made pelleted catalyst for optimum reaction rate.

    Notes: An approximate solution to the problem of freezing of an isotropic, semi-infinite slab is proposed for the situation where Newton's cooling at the surface of the slab applies. Comparison with the existing exact solution shows the approximate solution to be practical.The heat-balance integral method is used with the assumptionof linear temperature distribution in the frozen zone and of a parabolic temperature profile in the liquid zone. The final expression for the depth of solidification, however, seems to be only little affected by the particular temperature profiles chosen.
