Some Physical Properties of Dimethyl Sulfoxide-Water Binary System

Abstract

We have yet very little information as to some physical properties of dimethyl sulfoxide-water binary system. The purpose of this paper was to determine the physical properties of this system, such as refractive index, density, viscosity, surface tension, coefficient of expansion, specific heat, heat of mixing, solid-liquid equilibrium, vapor-liquid equilibrium, and the relation between diameter of bubble and diameter of drop. Dimethyl sulfoxide has an excellent affinity to water. The interaction between dimethyl sulf oxide and water was investigated by McAllisters' two body model, which has been derived to study the viscosity of binary mixtures.
