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

Abstract

The excess molar volumes (V_m^E) 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 318.15 K and atmospheric pressure over the entire composition range. The results have been used to estimate the partial molar volumes <img src='http://nopr.niscair.res.in/jinfo/vbar.gif' border=0>_m,i of the components. The excess values have been fitted to Redlich-Kister polynomial equation. The changes of V_m^E and <img src='http://nopr.niscair.res.in/jinfo/equation172.gif' border=0> with composition and temperature have been discussed with reference to the nature of interactions between the component molecules.
