    Notes: Abstract New experimental data on the thermal conductivity of 14 organic liquids at atmospheric pressure are presented in the temperature range from 25 to 100°C. The liquids measured are five n-alkanes (C6, C7, C8, C10, C12), cyclohexane, six aromatic hydrocarbons (benzene, ethylbenzene, o-, m-, p-xylenes, isopropylbenzene) and two phenyl halides (chloro-, bromobenzenes). The measurements were performed by a transient hot-wire method on a relative basis. The thermal conductivity of toluene, which was selected as a reference liquid, was determined on an absolute basis with another transient apparatus. The precision of the present experimental results is within ±1.2%. The uncertainty of the thermal conductivity values is estimated to be within ±2%; this includes the uncertainty of the values of toluene as the reference liquid. The experimental results for each liquid are represented satisfactorily by a linear equation in temperature. At a reduced temperature T/T c=0.5, thermal conductivity has a simple relation with the molar density for each homologous series of liquids.

    Notes: Abstract New experimental data on the thermal conductivity of liquid halogenated ethanes, R112 (CCl2F-CCl2F), R113 (CCl2F-CClF2), R114 (CClF2-CClF2), R114B2 (CBrF2-CBrF2), and R123 (CHCl2-CF3), are presented in the temperature range from 283 to 348 K at pressures up to 200 MPa or the freezing pressures. The measurements were carried out by a transient hot-wire apparatus within an uncertainty of ±1.0%. The thermal conductivity data obtained have been analyzed by means of the corresponding-states principle and other empirical methods. It is found that the corresponding-states correlation λ=f(Tr, Pr) holds well for R112, R113, and R114. The thermal conductivity can also be correlated satisfactorily with temperature, pressure, and molar volume by a similar expression to the Tait equation and the dense hard-sphere model presented by Dymond.

    Notes: Abstract New experimental data on the thermal conductivity and the density of liquid toluene are presented in the temperature range 0–100°C at pressures up to 250 MPa. The measurements of thermal conductivity were performed with a transient hot-wire apparatus on an absolute basis with an inaccuracy less than 1.0%. The density was measured with a high-pressure burette method with an uncertainty within 0.1%. The experimental results for both properties are represented satisfactorily by the Tait-type equations, as well as empirical polynomials, covering the entire ranges of temperature and pressure. Furthermore, it is found that simple relations exist between the temperature dependence of thermal conductivity and the thermal expansion coefficient, and also between the pressure dependence of thermal conductivity and the isothermal compressibility, as are suggested theoretically.

    Viscosity of (water + alcohol) mixtures under high pressure (1987)

    Notes: Abstract New experimental viscosity data are presented for aqueous solutions of methanol, ethanol, 1-propanol, 2-propanol, and 2-methyl-2-propanol (t-butyl alcohol) in the temperature range from 283 to 348 K and pressures up to 120 MPa. The viscosity measurements were performed using a falling-cylinder viscometer on a relative basis with an uncertainty of less than 2%. The viscosity of pure alcohols and aqueous solutions is found to increase almost linearly with increasing pressure, whereas that of water decreases slightly with pressure at temperatures below 298 K. As for the composition dependence of the viscosity, a distinct maximum appears near 0.3–0.4 mole fraction of alcohol on all isobars at each temperature. The viscosity maximum shifts gradually to a higher alcohol concentration with increasing temperature and pressure. The isobars of aqueous 2-propanol and 2-methyl-2-propanol solutions have another shallow minimum near 0.9 mole fraction of alcohol below 323 K. The experimental results were analized empirically by a Tait-type equation and a free-volume theory. It was found that the isothermal viscosity data were satisfactorily correlated by these equations as functions of pressure and composition or of density and composition.

    Notes: Abstract The critical temperature and pressure, vapor pressure, and PVT relations for gaseous and liquid 1-chloro-1,2,2,2-tetrafluoroethane (R124) were determined experimentally. The vapor pressure was measured in the temperature range from 278.15 K to the critical temperature. The PVT measurements were carried out using two types of volumeters in the temperature range from 278.15 to 423.15 K, at pressure up to 100 MPa. The numerical PVT data of gaseous state are fitted as a function of density to a modified Benedict-Webb-Rubin equation. The pressure-volume relations of the liquid at each temperature are correlated satisfactorily as a function of pressure by the Tait equation. The critical density and saturated vapor and liquid densities are also determined and some of the thermodynamic properties are derived from the experimental results.

    Notes: Abstract Experimental data on the thermal conductivity of five liquid n-alkanes-hexane, heptane, octane, decane, and dodecane-are presented in the temperature range from 283 to 373 K at pressures up to 250 MPa or the freezing pressures. The measurements were performed on an absolute basis by an automated transient hot-wire apparatus. The uncertainty of the reported data is estimated to be within ±1%. The thermal conductivity of each alkane decreases almost linearly with rising temperature at a constant pressure and increases with increasing pressure at a constant temperature. Both the temperature coefficient of the thermal conductivity ¦(∂λ/∂T) p¦ and the pressure coefficient (∂λ/∂P) T decrease with increasing carbon number of alkanes. The experimental results were correlated with temperature and pressure by a similar expression to the Tait equation. It is also found that both the dense hard-sphere model presented by Menashe et al. and the modified significant structure theory proposed by Prabhuram and Saksena provide good representations of the present experimental results.

    Notes: Abstract In order to provide the newest and most reliable numerical data of thermophysical properties of fluids to the scientific and technical community as quickly as possible, the present data-base system was designed and constructed. This data base is concerned with 12 kinds of thermophysical properties at 7 defined physical states for about 400 pure fluids and their binary mixtures. The present system is constructed by means of a data-base management system, INQ, on our computer ACOS series System-2020 produced by Nippon Electric Co. Ltd. The data base is usable as (i) the conversational processing by TSS, (ii) the tabulation of property data in batch processing, and (iii) one of the subroutine libraries in the computation of a user's program. For users' convenience, 10 kinds of application programs have been prepared for the multipurpose retrievals, and anyone can use this data base liberally without any special knowledge on the structure or languages of this system. Furthermore, the function of graphic display of property data has been added recently.

    Notes: Abstract Viscosities of six higher 1-alkanols (1-hexanol, 1-octanol, 1-decanol, 1-dodecanol, 1-tetradecanol, and 1-hexadecanol) have been determined at temperatures from 298 to 348 K and pressures up to 200 MPa. The viscosity measurements were performed using a falling-body viscometer with an uncertainty of ±5%. Simple equations are presented to express the experimental viscosities as a function of temperature and pressure within the experimental uncertainty. The relationship between the viscosity and the density of these alkanols is discussed in terms of the significant structure theory extended to high pressures.
