Measurements of excess molar enthalpies H-E at 298.15 K have been made for binary liquid mixtures of 1,1,2,2-tetrachloroethane with acetone, dibutyl ether, acetonitrile, and dimethyl sulfoxide. The values of H-E at 298.15 K are negative for all four systems. These results indicate the existence of specific interactions of CHCl2CHCl2 with all these compounds. The excess molar enthalpies (in absolute values) of these systems decrease in the order dimethyl sulfoxide > acetone > acetonitrile > dibutyl ether.
