STUDY OF THERMOACOUSTICAL PARAMETERS FREE VOLUME AND INTERMOLECULAR FREE LENGTH OF MULTICOMPONENT LIQUID SYSTEMS

摘要

Intermolecular free length and free volume of ternary mixtures (ethanol + N, N-DMF + cyclohexane) and (cyclohexane + n-heptane + Toluene) have been computed using ultrasonic velocity and density and the values thus obtained are compared with the values obtained from thermodynamic relation of the intermolecular free length and free volume. A satisfactory and good agreement between the values from the two methods which are very close to each other, proves the applicability of thermoacoustical parameters for the calculation of the available volume in ternary liquid mixtures.
