Abstract: The densities and speeds of sound of mixtures of 1,2 dichloroethane, 1,1,2 trichloroethane, 1,1,2,2 tetrachloroethane, trichloroethene and tetrachloroethene with N-methylacetamide, over the entire range of composition, have been measured at a temperature of 308.15 K. The deviations in speed Δu, isentropic compressibility ΔkS, intermolecular free-length ΔLF and relative association RA have been computed using speed and density values. The Δu values are negative whereas ΔkS and ΔLF values are positive for all the systems, which indicate the non-specific interactions between unlike molecules. The results are discussed in the light of intermolecular interactions occurring in the solutions. The computed results of ΔkS, have been fitted to a Redlich-Kister type polynomial equation.
