Abstract :

Densities, speeds of sound and refractive indices of diethyl carbonate + nitrobenzene, + chlorobenzene, and + ethylbenzene have been measured at (293.25, 303.15, 313.15 and 323.15) K over the entire composition range and at atmospheric pressure. From these measurements, excess molar isentropic compressibilities ( ), excess molar volumes (VE) and refractive index deviations (ΔnD) were calculated. The results were fitted to the RedlichKister polynomial equation in order to derive the adjustable parameters and standard deviations to study the nature of the molecular interactions in the mixtures.
