Abstract

Ultrasonic velocity (U), density (ρ) and viscosity (η) for the ternary liquid mixtures of benzaldehyde+tetrachloromethane+o-cresol, benzaldehyde+tetrachloromethane+m-cresol and benzaldehyde+tetrachloromethane+p-cresol have been measured as a function of the composition at 303, 308 and 313K. The experimental data have been used to calculate some excess acoustical parameters, such as adiabatic compressibility (β^E), free length (L_f^E) and free volume (V_f^E). The results are discussed and interpretered in terms of specific interaction predominated by hydrogen bonding.
