Experimental Isobaric Vapor−Liquid Equilibrium for Binary Systems of Ethyl Methyl Carbonate + Methanol, + Ethanol, + Dimethyl Carbonate, or + Diethyl Carbonate at 101.3 kPa

Abstract

Isobaric vapor−liquid equilibrium (VLE) data were measured for the binary systems ethyl methyl carbonate (EMC) + methanol, + ethanol, + dimethyl carbonate (DMC), and + diethyl carbonate (DEC) at 101.3 kPa using a vapor−liquid equilibrium still. The thermodynamic consistency of the experimental data was verified by Herington(1) method. The experimental VLE data were correlated with the Wilson, NRTL, and UNIQUAC activity coefficient models. The results show that the calculated values of vapor phase mole fraction and boiling temperature by the Wilson, NRTL, and UNIQUAC models agree well with the experimental data. Futhermore, azeotropic behavior was observed for the binary system of ethanol + EMC.
