    Infrared studies of cryogenic transitions in poly(ethylene terephthalate) and polystyrene (1971)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 15 (1971), S. 1237-1245

    Notizen: Infrared absorbance measurements as a function of temperature down to 13°K have been made on poly(ethylene terephthalate) and polystyrene. Transition temperatures are assigned to the temperatures where there are abrupt changes in the absorbance or integrated band intensities. Bands of known structural origin arising from either crystal-line or amorphous phases are studied to probe the structure basis and environment effect for each transition. Transitions are found around 50, 120, 180, and 220°K for PET and around 50° and 235°K for polystyrene.

    Continuous phase mass transfer during formation of drops from jets (1979)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 25 (1979), S. 80-87 
    Details
    ISSN: 0001-1541
    Schlagwort(e): Chemistry ; Chemical Engineering

    Thema: Chemie und Pharmazie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: This study enables the extension of a recent design procedure for perforated plate extraction columns to include operation under jetting conditions. Correlations of experimental data are given for jet length, jet contraction, drop size, and mass transfer rates in continuous phase controlled liquid-liquid systems. Systems exhibiting very low mass transfer rates were used, and this gave significantly different results from those obtained earlier with moderate rates of mass transfer.

    Dispersed phase mass transfer during drop formation under jetting conditions (1977)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 23 (1977), S. 701-714

    ISSN: 0001-1541

    Notizen: A recent design procedure for perforated plate extraction columns requires extension to include jetting conditions at each perforation. For this purpose, correlations are obtained for jet length, jet contraction, drop size, and mass transfer coefficients in disperse phase controlled liquid-liquid systems. Experimental variables include nozzle size, flow velocity, and physical properties.
