A group additivity method has been generated which makes it possible to estimate, from the structural formulas alone, the energy of vaporization and the molar volume at 25/sup 0/C of many nonpolar organic liquids. From these two parameters and appropriate thermodynamic relations it is then possible to predict the vapor pressure of the liquid phase and the solubility of various gases in nonpolar organic liquids. It is also possible to use the data to evaluate organic and some inorganic liquids for use in gas separation stages or liquids as heat exchange fluids in prospective thermochemical cycles for hydrogen production.
