ABSTRACT

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 (VE) and deviations in viscosity (Dg). 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 (d0) are also utilized in the qualitative analysis to elicit the specific interactions like complex formation as well as the saturation of chlorine atoms with p-electrons.
