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

摘要

Densities p and dynamic viscosities ? 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_m~E, excess partial molar volumes V_m~E, limiting excess partial molar volumes V_m~~(E,8), and viscosity deviations ?? 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.
