Excess molar volumes and viscosities for binary and ternary mixtures of vinyl acetate + trichloroethylene + tetrachloroethylene at 298.15 K

Abstract

Densities ρ and dynamic viscosities η of ternary mixtures consisting of vinyl acetate + trichloroethylene + tetrachloroethylene and related binary mixtures have been measured over the whole composition range at T = 298.15 K. The data obtained were used to calculate excess molar volumes $$ V_{\text{m}}^{\text{E}} $$ , excess partial molar volumes $$ V_{{{\text{m,}}i}}^{\text{E}} $$ , limiting excess partial molar volumes $$ V_{{{\text{m,}}i}}^{{{\text{E,}}\infty }} $$ , and viscosity deviations ∆η of binary and ternary mixtures. Data of excess molar volumes and viscosity deviations of binary systems were fitted to the Redlich–Kister and Cibulka equations, respectively. Viscosities of the binary mixtures have been correlated by means of several semi-empirical equations to determine the fitting parameters and the standard deviations. The experimental data are analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
