Excess molar enthalpies and excess molar volumes of the ternary system 1,2-dichlorobenzene plus benzene plus hexane at 298.15 K

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