摘要：

Isobaric vapour-liquid equilibria for the system ethanol + methanol + MTBE were determined at 101.32 kPa. These data for this ternary system were then compared with predictions made using the Wilson, NRTL and UNIQUAC equations and the binary interaction parameters for the corresponding constituent binary subsystems. The predictions deviated only slightly from the experimental data. Moreover, these deviations were smaller than those obtained when the equilibrium data were predicted using the ASOG, UNLFAC, UNIFAC-Lyngby or UNIFAC-Dortmund group-contribution methods, among which the latter method afforded the most satisfactory predictions.
