摘要
The values of density and viscosity of the binary liquid mixtures of N-methylacetamide with some chloroethanes (1,2-dichloroethane, 1,1,2-trichloroethane and 1,1,2,2-tetrachloroethane) and chloroethenes (trichloroethene and tetrachloroethene) are measured over the entire range of composition at T = 308.15 K. These values have been used to calculate the excess molar volumes ( V-E) and deviations in viscosity (Delta(eta)). The excess molar volumes and deviations in viscosity are fitted to a Redlich-Kister type equation. Other parameters like excess Gibbs free energy of activation of viscous flow (G(*E)) and Grunberg-Nissan interaction constant (d') are also utilized in the qualitative analysis to elicit the specific interactions like complex formation as well as the saturation of chlorine atoms with pi-electrons.
