The bulk properties of ethylene glycol-dimethylsulfoxide mixtures over the temperature range 278–323 K at <Emphasis Type="Italic">p</Emphasis> = 0.1 MPa

The densities of ethylene glycol-dimethylsulfoxide binary mixtures were measured over the temperature range 278–323.15 K at atmospheric pressure using a vibrational densimeter. The excess molar volumes, apparent molar volumes, partial molar volumes of mixture components, volumetric thermal expansion coefficients, and partial molar volumetric thermal expansion coefficients were calculated. The excess molar volumes were described by the Redlich-Kister equation, and the partial molar volumes were calculated by two methods. The density-composition dependence contained a weak maximum, which disappeared as the temperature increased. The excess molar volumes were negative, and deviations from ideality increased as the temperature grew.
