Thermodynamics of Binary Liquid Mixtures Containing Cyclohexane Part 1

Abstract

Ultrasonic velocities in and densities of binary liquid mixtures of benzene, carbon tetrachloride, carbon disulphide, P-xylene, m-xylene, o-xylene toluene, dioxan and tetralin with cyclohexane as common component have been determined at room temperature, The nature of the excess compressibility and excess volume of these mixtures has been discussed in the light of the recently developed molecular theories of solutions. The agreement between the calculated and experimental excess functions has been found to be good in all cases excepting the system cyclohexane-toluene. The nature of the velocity ν s mole fraction curves has been explained by extending the concept of available volume and intermolecular free-length to liquid mixtures.
