The solubility of iodine in mesitylene, p-xylene, ethyl ether, ethyl alcohol, cyclohexane, 2,2-dimethylbutane and perfluoro-n-heptane has been measured over a range of temperature. The solvation in the case of mesitylene and p-xylene increases the iodine solubility over the values for regular solutions, the increase being greatest for mesitylene. The enhancement of iodine solubilities in these solvents is in good agreement with equilibrium data obtained from earlier spectroscopic measurements and therefore provides further evidence for the existence of an acid-base interaction (in the Lewis sense) between aromatic hydrocarbons and iodine. Iodine solubilities (in unsolvated solutions) obtained in this and earlier investigations are in satisfactory accord with the behavior predicted from the internal pressures of the pure solvents. 1950, American Chemical Society.
