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, i...

Description
Summary: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. Keywords: partial molar volume, solubility, physical solvents.
