    Notizen: Volumetric data on gas mixtures and vapor-phase data for gas-liquid equilibria have been correlated within the framework of the theory of corresponding states. An expression based on the London potential for dispersion forces was used to compute characteristic temperatures for various binary systems, and a correlation was developed relating these temperatures to the polarizabilities, ionization potentials, and critical volumes of the pure components. The correlation shows how the molecular shape of a liquid affects its vapor-phase solubility. With the help of this correlation it is possible to make very good predictions of such gas-liquid equilibria as are required in high-pressure distillation, absorption, and petroleum hydrofining operations.

    Notizen: The vapor-phase solubilities of carbon tetrachloride, iso-octane, toluene, and n-decane were measured in compressed hydrogen, nitrogen, and carbon dioxide at 50° and 75°C. and at various pressures between 20 and 90 atm. The virial equation of state was used to describe the volumetric properties of the vapor mixtures, and the second virial cross coefficients were evaluated from the solubility data. The results indicate that the vapor phase departs from ideality very quickly for these systems as the pressure increases, particularly at pressures greater than 10 atm.
