Isothermal vapor-liquid equilibrium (VLE) data, excess molar volumes V(m)E, and excess molar enthalpies H(m)E have been determined for dimethyl carbonate + 1,2-dichloroethane or + 1,1,1-trichloroethane. V(m)E and H(m)E were measured at 298.15 and 313.15 K. VLE measurements were also made at 333.15 K. The excess Gibbs free energy for the two systems has been derived at the three temperatures.
