✦ Synopsis

Precise and accurate values of the excess enthalpies of {xC

have been determined over the whole composition range at T = 298.15 K. Although all the excess enthalpies are small, those of {xC 6 H 6 + (1 -x)C 6 D 6 } and {xC 6 H 12 + (1 -x)C 6 D 12 } are endothermic and those of {xCH 2 Cl 2 + (1 -x)CD 2 Cl 2 } are exothermic. A linear correlation is found between the excess enthalpies at x = 0.5 and the reciprocal of the number of deuterium atoms bound to the carbon atoms of a deuterated compound.
