Study of Thermo Physical Properties of Binary Liquid Mixtures ofTrichloroethylene with 1-Pentanol at 308 K

Density and ultrasonic study for the binary mixtures of trichloroethylene and 1-pentanol over the entire concentration range were measured at temperatures 308 K. The experimental data wasthen used to calculate the compressibility, acoustic impedance, molecular free length, inverserelaxation time, and excess parameters. The values of excess properties further fitted withRedlich–Kister polynomial equation to estimate the binary coefficients. The resulting excessfunctions were interpreted in terms of the interactions between the molecules in the binarymixtures. Results confirmed that hydrogen-bonded intermolecular interaction took place betweentrichloroethylene and 1-pentanol.
