Ultrasonic study of molecular interaction in binary liquid mixtures

摘要

The ultrasonic velocities were measured in binary mixtures of o-cresol, p-cresol, ochlorophenol and p-chlorophenol with CCl_4 at 303.15 K. The relative merits of Nomoto's theory, Van Deal and Vangeel ideal mixing relation, free length theory and collision factor theory in the binary liquid mixtures are compared. The values of molecular interaction term α for the liquid mixtures are used to understand the molecular interactions.
