ABSTRACT

Density,q, ultrasonic speed, u, and viscosity, g of binary mixtures of toluene with acetone (AC), ethyl methyl ketone (EMK), and acetophenone (AP), including those of pure liquids are measured over the entire composition range at temperatures (298.15, 303.15, and 308.15) K respectively. From these experimental results, deviations in isentropic compressibility, and ultrasonic speed, excess intermolecular free length, excess Gibbs free energy of activation, partial molar volumes, partial molar compressibilities, and their excess values of the components at infinite dilution are calculated. The values of delta isentropic compressibility and excess intermolecular free length are found to be negative, and those of delta ultrsonic speed and excess Gibbs free energy of activation are found to be positive, indicating the presence of specific interactions between toluene and ketone molecules and the interactions follow the order: AC greater than EMK greater than AP.
