Densities and viscosities of binary liquid mixtures of N-methylacetamide with some chloroethanes and chloroethenes at T = 308.15 K

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 (Δη  ). 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∗EG∗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 π-electrons.
