  • Abstract

    Ultrasonic velocity (U) and density (ρ) of different concentrations of binary solutions of dimethyl sulphoxide (DMSO) and water and acetonitrile (ACN) and water have been studied at 303.15 K. From the experimental data various acoustical parameters such as isentropic compressibility (Ks), acoustic impedance (Z), intermolecular free length (Lf) and Rao’s Constant (R) have been evaluated. Also hydrodynamic flow studies of different concentrations of experimental solvents through anisotropic cellulose acetate membrane are described and used to evaluate transport properties such as permeability coefficient (Lp) and frictional coefficient (Fwm) The results are discussed in the light of intermolecular interactions occurring in the solutions and also in terms of interactions between membrane and solution.
