Excess Molar Enthalpies and Excess Molar Volumes of the Ternary System 1,2-Dichlorobenzene + Benzene + 1-Chlorohexane at 298.15 K

Abstract

Excess molar enthalpies and excess molar volumes for the ternary system {(x1)1,2-dichlorobenzene + (x2)benzene + (1 − x1 − x2)1-chlorohexane} and the involved binary mixture {(x)benzene + (1 − x)1-chlorohexane} have been determined at the temperature 298.15 K and atmospheric pressure. Values of excess molar enthalpies were measured using a Calvet microcalorimeter, and excess molar volumes were determined from the densities of the pure liquids and mixtures, using a vibrating-tube densimeter. The experimental values were used to test the results obtained with empirical expressions for estimating ternary properties from binary data.
