Excess molar volumes (V-E) of dimethyl carbonate (DMC) + benzene, DMC + toluene, DMC + n-heptane, and DMC + isooctane are obtained from the measured densities at 298.15 K by using a digital vibrating-tube densimeter. All the measured excess molar volumes are correlated with the five-parameter Redlich-Kister polynomial. Isothermal vapor-liquid equilibrium (VLE) data are measured for the binary systems of benzene + DMC, DMC + toluene, DMC + n-heptane, and DMC + isooctane at 333.15 K by a using headspace gas chromatography (HSGC) method. The experimental binary VLE data were correlated with common g(E) model equations.
