Prediction of unsymmetric convention liquid-phase activity coefficients of hydrogen and methane

A corresponding states method has been developed to predict the binary parameter in the unsymmetric‐convention one‐term Margules relation for binary activity coefficients of H2 and CH4 in solvents. In addition to the solvent density, only characteristic volumes used previously for partial molar volu...

Description
Summary:A corresponding states method has been developed to predict the binary parameter in the unsymmetric‐convention one‐term Margules relation for binary activity coefficients of H2 and CH4 in solvents. In addition to the solvent density, only characteristic volumes used previously for partial molar volumes at infinite dilution and pure solvent compressibility are required. Comparisons with experiment for nonpolar solvents indicate that use of the method is usually significantly more accurate than assuming ideal solution (Henry's law).
