ABSTRACT

Isothermal vapor-liquid equilibrium data at 333.15 K are reported for the ternary systems {di-methyl carbonate (DMC) + ethanol + benzene} and {DMC+ ethanol + toluene} as determined with headspace gas chromatography. The experimental ternary vapor-liquid equilibrium (VLE) data were correlated with different activity coefficient models. The excess volume (VE) and deviations in molar refractivity data are reported for the binary systems {DMC+ benzene} and {DMC+ toluene} and also for the ternary systems {DMC+ ethanol + benzene} and {DMC+ ethanol + toluene} at 298.15 K. These VE and deviations in molar refractivity data were correlated with the Redlich-Kister equation for binary systems and the Cibulka equation for ternary systems.
