Acoustical Studies of Molecular Interaction in Ternary Liquid Mixture of Cresols With Benzaldehyde and Tetrachloromethane Solutions at 303, 308 and 313K

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.
