Vapor−Liquid Equilibria for the Ternary Systems of Methyl tert-Butyl Ether + Methanol + Methylcyclohexane and Methyl tert-Butyl Ether + Methanol + n-Heptane and Constituent Binary Systems at 313.15 K

Abstract

Isothermal vapor−liquid equilibrium (VLE) data are measured for the ternary systems of methyl tert-butyl ether (MTBE) + methanol + methylcyclohexane (MCH) and MTBE + methanol + n-heptane and constituent four binary systems, MTBE + MCH, MTBE + n-heptane, methanol + MCH, and methanol + n-heptane, at 313.15 K. The experimental binary VLE data were correlated with common gE model equations. The correlated Wilson and NRTL parameters of the constituent binary systems were used to calculate the phase behavior of the ternary mixtures. The calculated ternary VLE data using Wilson and NRTL parameters and the predicted data using modified UNIFAC (Dortmund) model were compared with experimental ternary data.
