Excess molar volumes of some binary mixtures of dimethyl sulfoxide (dmso)‎ at various temperatures

Abstract EN

Knowledge of physical properties and phase equilibrium for organic solvents is necessary for the design and optimization of the equipment.

In this paper the excess molar volume VE of the binary liquid systems of DMSO (Dimethyl Sulfide) + Benzene, DMSO + o- Xylene, DMSO + 1, 4- Dioxin, and DMSO + Tetrahydrofuran, has been calculated from density measurements at 293.15, 298.15, and 303.15 K and at atmospheric pressure over the entire composition range.

The experimental excess function VE was fitted to the Redlich-Kister polynomial equation to evaluate the adjustable parameters (Ai) and standard deviation (σ).
