Abstract: The densities and sound speeds of mixtures of acetophenone, propiophenone, paramethyl acetophenone and parachloro acetophenone with acrylonitrile, over the entire range of composition, have been measured at a temperature of 308.15 K. The deviations in speed u, isentropic compressibility kS, intermolecular free-length LF and relative association RA have been computed using speed and density values. The u values are positive whereas kS and LF values are negative for all the systems, which indicate the specific interactions between unlike molecules. The results are discussed in the light of intermolecular interactions occurring in the solutions. The computed results of kS, have been fitted to a Redlich-Kister type polynomial equation.
