The solubility of water in low-dielectric solvents

Abstract

The solubility of water has been measured in several low-dielectric solvents at 25 °C, and the values in the nonpolar solvents are treated by using a modification of the Scatchard–Hildebrand equation. The water–solvent interaction parameter in this equation is represented by a new relationship involving the separate contributions due to dispersion and polar interactions. A new method is given for calculation of the dispersion component of the solubility parameter of a polar species. Formation constants are reported for 1:1 water–solvent complexes in carbon tetrachloride, benzene, toluene, and p-xylene.
