Abstract

A method is described for estimating solubility by fitting both solute and solvent properties in a single equation. The method is illustrated by examining the solubilities of five rare gases (He, Ne, Ar, Kr, Xe) and five ‘permanent’ gases (O₂, N₂, CH₄, CF₄, SF₆) in either n-alkane (C₅H₁₂to C₁₆H₃₄) or alkan-1-ol (CH₃OH to C₁₁H₂₃OH) solvents. Generally, the correlation (R²) values of the fits achieved were significantly better than 0.9. It is suggested that similar methods can be used for estimating other physico-chemical properties such as excess molar volumes and enthalpies of solution.
