Volumetric properties of binary mixtures of cyclohexane with 2-ethoxyethanol at 303.15, 308.15 313.15 and 318.15 K

BHAVANI, MOPIDEVI DURGA

Abstract

The excess molar volumes (VmE) for binary liquid mixtures of cyclohexane + 2-ethoxyethanol have been calculated from the experimental values of density and ultrasonic velocity at temperatures 303.15, 308.15, 313.15 and 318.15K and atmospheric pressure over the entire composition range. The results have been used to estimate the partial molar volumes  of the components. The excess values are fitted to Redlich-Kister polynomial equation. The changes of VmE and with composition and temperature have been discussed with reference to the nature of interactions between the component molecules.
