PARTIAL MOLAR VOLUMES OF ACIDIC GASES IN PHYSICAL SOLVENTS AND PREDICTION OF SOLUBILITIES AT HIGH-PRESSURES

Partial molar volumes at infinite dilution for three acidic gases (carbon dioxide, hydrogen sulfide, and sulfur dioxide) in four physical solvents (propylene carbonate, methyl cyanoacetate, N-formyl morpholine, and Selexol) have been obtained using our new dilatometer. These partial molar volumes, in combination with the Henry's law constants obtained previously, have been used in the Krichevsky-Kasarnovsky equation for predicting the solubilities of acidic gases in physical solvents at high pressures.
