Study of ultrasonic properties of binary liquid mixtures

Abstract

Density and ultrasonic study for the binary mixtures of Trichloroethylene and 1-pentanol over the entire concentration range were measured at temperatures 315 K. The experimental data then used to calculate the compressibility, and acoustic impedance, molecular free length, Inverse relaxation time and Excess Parameters. The values of excess properties further fitted with Redlich–Kister polynomial equation to estimate the binary coefficients. The resulting excess functions were interpreted in terms of the interactions between the molecules in the binary mixtures. Results confirm that hydrogen-bonded intermolecular interaction takes place between Trichloroethylene and 1-pentanol.
