Vapor–liquid equilibria for binary mixtures containing ethyl tert butyl ether (ETBE) + (p-xylene, m-xylene and ethylbenzene) at 101.3 kPa

Abstract

Isobaric vapor–liquid equilibria data at 101.3 kPa were reported for the binary mixtures ethyl tert butyl ether (ETBE) + (p-xylene, m-xylene and ethylbenzene). VLE experimental data were tested for thermodynamic consistency by means of a modified Dechema test and was demonstrated to be consistent. The activity coefficients were correlated with the Margules, van Laar, UNIQUAC, NRTL, and Wilson equations. The Analytical Solution Of Groups (ASOG) model also was applied for prediction.
