Excess molar enthalpies, H m E , and excess molar volumes, V m E , have been measured at T ) 298.15 K and normal atmospheric pressure for the binary 1,2-dichlorobenzene + (benzene, hexane, or 1-chlorohexane) and 1,3-dichlorobenzene + (benzene, hexane, or 1-chlorohexane) systems using a Calvet microcalorimeter and a vibrating tube densimeter, respectively. The experimental values of H m E and V m E of the mixtures are found to be positive or negative depending on the type and magnitude of the interactions involved in each process. The results are compared with those found in the literature.

Excess molar enthalpies, H m,123 E , and excess molar volumes, V m,123 E , for the ternary system {x 1 1,2dichlorobenzene + x 2 benzene + (1 -x 1 -x 2 ) hexane} and excess molar enthalpies H m E of the binary mixture {x benzene + (1 -x) hexane} 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 vibratingtube densimeter. The experimental values are compared with the results obtained with empirical expressions for estimating ternary properties from binary data.
