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 6permanent7 gases (O2, N2, CH4, CF4, SF6) in either n-alkane (C5H12 to C16H34) or alkan-1-ol (CH3OH to C11H23OH) solvents. Generally, the correlation (R2) values of the fits ac...

The revised general solubility equation (GSE) proposed by Jain and Yalkowsky is used to estimate the aqueous solubility of a set of organic nonelectrolytes studied by Jorgensen and Duffy. The only inputs used in the GSE are the Celsius melting point (MP) and the octanol water partition coefficient (K(ow)). These are generally known, easily measured, or easily calculated. The GSE does not utiliz...
