Thermodynamic study of complex formation between dimethyl sulphoxide and chloroform

Abstract

We have used vapour pressures and enthalpies of mixing at 298 K for calculation of K, ΔG o, ΔH o, and ΔS o of formation of AB and AB 2 complexes in dimethyl sulphoxide+ chloroform. Equilibrium constants at other temperatures (292 to 328 K) derived from vapour pressures at these temperatures are consistent with ΔH o and ΔS o derived from experimental quantities determined at 298 K.
