ABSTRACT:Isobaric vapor-liquid equilibrium (VLE) data for binary system of [2-Methoxyethanol + H2O] was measured which using CE-1 equilibrium cell at 100 kPa. The thermodynamic consistency of the experimental data was tested with the Herington method and passed. Then the experimental data were correlated using the nonrandom two-liquid (NRTL) and Wilson activity coefficient models, and the more precise interaction parameters were obtained.

Keywords:Vapor-liquid equilibrium, thermodynamic consistency, Herington method, activity coefficient
