The velocity of ultrasonic waves, density and viscosity of three binary liquid mixtures namely Benzophenone + 2-Butanol, Benzophenone + Allylalcohol, Benzophenone + 2-Ethoxyethanol, and three ternary liquid mixtures namely Benzophenone + Toluene + 2-Butanol, Benzophenone + Toluene + Allylalcohol, Benzophenone + Toluene + 2-Ethoxyethanol have been measured. From the precise data, some of the acoustical parameters such as adiabatic compressibility inter molecular free length, relaxation time, acoustic impedance, bulk modulus, attenuation, relative association and Gibb’s free energy values are computed for the six systems at 303K and at atmospheric pressure. The performances of these parameters with composition of the mixtures have been conferred in terms of molecular interaction between solute and solvent.
