Isothermal vapor–liquid equilibrium at T = 333.15 K and excess volumes and molar refractivity deviation at T = 298.15 K for the ternary mixtures {di-methyl carbonate (DMC) + ethanol + benzene} and {DMC + ethanol + toluene}

Abstract

Isothermal vapor–liquid equilibrium data at 333.15K 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 (ΔR) 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 298.15K. These VE and ΔR data were correlated with the Redlich–Kister equation for binary systems and the Cibulka equation for ternary systems.
