Notes:
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.
