EXCESS MOLAR ENTHALPIES OF 1,1,2,2-TETRACHLOROETHANE WITH ACETONE, DIBUTYL ETHER, ACETONITRILE, AND DIMETHYL-SULFOXIDE AT 298.15 K

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 indicat e the existence of specific interactions of CHCl2CHCl2 with all these compounds. The excess molar enthalpies (in absolute values) of these s ystems decrease in the order dimethyl sulfoxide > acetone > acetonitri le > dibutyl ether.
