Estimation of some important thermodynamic and thermophysical properties of ternary liquid mixtures from ultrasonic velocity and density data

An attempt has been made to determine internal pressure and energy of vaporization and their corresponding excess parameters from experimentally determined values of ultrasonic velocity and density for four ternary liquid mixtures at 298.15 K. Furthermore, enthalpy of vaporization, pseudo Gruneisen parameter, cohesive energy density and solubility parameters for the four multicomponent liquid mixtures under investigation have also been computed to get a better understanding for the intermolecular interactions taking place thereof.
