Solubility correlations. Part 1. Simultaneous fitting of both solute and solvent properties.
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 (O(2), N(2), CH(4), CF(4), SF(6)) in either n-alkane (C(5)H(12) to C(16)H(34)) or alkan-1-ol (CH(3)OH to C(11)H(23)OH) solvents. Generally, the correlation (R(2)) 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.
