Studies in regular solution theory. Part 1.—Solubolity studies of tetraphenyltin in simple non-polar solvents

Abstract

The solubility of tetraphenyltin in a number of non-polar solvents is presented. The data are analyzed in terms of Hildebrand's theory of regular solutions. The large molar volume of this solute requires the inclusion of a Flory-Huggins term in the saturation solubility equation. The possible limitation of the interaction-energy geometric-mean rule are examined and a comparison is made with data for the solubility of stannic iodide, iodine and sulphur in a similar set of solvents.
