Excess thermo-acoustical parameters in the study of molecular interactions in binary liquid mixtures containing quinoline with arenes (benzene and toluene) at temperatures T = (303.15, 308.15, 313.15 and 318.15)K

Densities, ultrasonic velocities and viscosities have been measured in binary liquid mixtures of quinoline with arenes(benzene and toluene)at temperatures T = (303.15, 308.15, 313.15 and 318.15)K over the entire molefraction range of quinoline. From the experimentally measured data, excess thermo-acoustical parameters such as excess intermolecular freelength (L-f(E)), excess adiabatic compressibility (beta(E)), excess free volume (V-f(E)), excess internal pressure (pi(E)),excess enthalpy (H-E) and excess Gibb's free energy of activation function (G*(E)) have been calculated. These results are fitted to the Redlich-Kister polynomial equation. These results have been explained on the basis of intermolecular interactions present between the component molecules of the liquid mixtures. (C) 2016 Elsevier B.V. All rights reserved.
