A high-pressure flow-mixing isothermal microcalorimeter is used to determine the excess molar enthalpies of four binary systems for dimethyl carbonate and (methanol, ethanol, 1-propanol, and 2-propanol) at T E (298.15, 313.15, and 328.15) K and p = (0. 1, 1.0, and 10.0) MPa. The smooth values of H-m(E) calculated by the Redlich-Kister equation are also compared with the experimental results.
