ABSTRACT:

Density (r), viscosity (h) and ultrasonic velocity (U) measurements have been carried out in three ternary liquid mixtures of chlorobenzene, nitrobenzene and bromobenzene with acetophenone and 1-propanol mixtures at 303, 308, 313K. From the experimental measurements, the acoustical parameters such as adiabatic compressibility (b), free volume (Vf), and Gibb?s free energy (DG) have been calculated. The excess value of the above parameters and Grunberg-Nissan interaction parameter (d) have also been computed and discussed in the light of molecular interaction in the mixtures.

KEYWORDS: Ultrasonic velocity; compressibility; Gibb?s free energy; interaction parameter
