Abstract:
: Density (p), viscosity (77) and ultrasonic velocity (U) of ternary liquid mixtures of cresols namely o-cresol, m-cresol and p-cresol with benzaldehyde and tetrachloromethane solution have been determined at 303, 308 and 313 K over the entire composition range. The measured data has been utilized to estimate the excess viscosity (175), excess Gibb’s free energy (AGE) and Grunberg’s interaction parameter (d). The variation of excess parameter indicates that there are intermolecular interactions among components of the ternary mixtures that lead to possible hydrogen bond formation between unlike molecules.
