The values of ultrasonic velocity (u), density (ρ), and viscosity (η) have been measured experimentally in the binary liquid mixture containing 1-butanol and hexane over the entire range of composition at different temperatures 313.15 K, 318.15 K and 323.15 K. This experimental data have been used to calculate the acoustical parameters such as adiabatic compressibility (β), free length (Lf), molar volume (Vm) and acoustic impedance(z). The results have been qualitatively used to explain the molecular interactions between the components of the liquid mixture.

Various statistical and empirical theories of ultrasonic velocity have been applied to a binary liquid mixture (benzene + nitrobenzene) at elevated pressures and their validity have been tested. A pressure-dependent study of ultrasonic velocities has been made at three different temperatures (293.15, 303.15, and 313.15 K). The agreement between the theory and experiment is found to be satisfactory. Keywords: ultrasonic velocity, benzene + nitrobenzene, pressure dependent, theoretical evaluation, binary mixtures at elevated pressures.

The ultrasonic velocity, density and viscosity in binary liquid mixture cyclohexane witho-xylene have been determined at different temperatures from 303.15 to 318.15 K over the whole composition range. The data have been utilized to estimate the excess adiabatic compressibility (βE), excess volumes (VE), excess intermolecular free length (LfE), excess internal pressure (πE) and excess enthalpy (HE) at the above temperatures. The excess values have been found to be useful in estimating the strength of the interactions in the liquid mixtures. Analysis of these parameters indicates that there are weak interactions among the components of the binary mixtures.

Ultrasonic velocity is measured experimentally at 3MHz frequency in the binary liquid mixture containing aniline and anisole at different temperatures over the entire composition range and theoretical values of ultrasonic velocity have been evaluated by using Nomoto’s relation, Impedance relation, Van Dael ideal mixture relation. These theoretical values are compared with the experimental values. A good agreement has been found between experimental and theoretical ultrasonic velocities.
