Intermolecular Interaction for Binary Mixtures of Propylene Carbonate with Acetonitrile, Dimethyl Carbonate, Diethyl Carbonate at Different Temperatures: Density and Viscosity

Abstract

Abstract In this work, the experimental densities and viscosities have been determined for (propylene carbonate+acetonitrile, or dimethyl carbonate, or diethyl carbonate) binary mixtures over the whole concentration range at temperatures (293.15–333.15 K) and the atmospheric pressure. Excess molar volumes (VE ), viscosity deviations (Δη), thermal expansion coefficients (α) and excess Gibbs free energy of activation of viscous flow (ΔGE *) were calculated. These excess functions and deviations were fit with the Redlich–Kister type polynomial equation. The sign and magnitude of these excess properties have been used to interpret the results in terms of intermolecular interactions and structural effects. The results obtained for viscosity of binary mixtures were also used to test the semi-empirical relations of Grunberg-Nissan and Katti-Chaudhri equations.
