The behaviour of molecules within liquid mixtures is qualitatively assessed by studying their acoustic and thermodynamic properties, which involves measuring ultrasonic velocity (u), density (ρ), and viscosity (η) of various binary mixture of different concentration of an ester alpha terpinyl acetate (α-TA) and butanol-1. The values of these experimental parameters were measured, at temperatures 293.15, 298.15, 303.15 and 308.15K. This data was used to calculate other thermodynamic parameters. These derived acoustic parameters were adiabatic compressibility (βs), acoustic impedance (Z), intermolecular free length (Lf), free volume (Vf), relaxation time (τ), internal pressure (πi), molar volume (Vm) and Rao’s constant, Wada’s constant. The influence of mole fraction concentration and temperature variations on several concerned parameters was investigated. The observed values of ultrasonic velocity, density, and viscosity increased with an increase in solute concentration, while they decreased with rise in temperature. The derived acoustical parameters showed a significant relationship with binary mixtures concentration and temperature.
