Abstract
Liquidus temperatures were measured for concentrated solutions of LiCl, CaCl2, ZnCl2, Zn(NO3)2, NaNO3 and Mg(NO3)2 in dimethyl sulphoxide. Crystalline solvates of salts with dimethyl sulphoxide which separated from these solutions were isolated and subjected to chemical and infrared spectroscopic analyses. It has been proved that in concentrated solutions in the mixed solvent water-dimethyl sulphoxide, the salts are preferentially solvated by dimethyl sulphoxide.
