Abstract
Vapor-liquid equilibrium at 94 kPa has been determined for the ternary system methyl 1,1-dimethylethyl ether (MTBE) + oxolane + heptane. The system deviates positively from ideality and no azeotrope is present. The ternary activity coefficients and the boiling points of the syste m have been correlated with the composition using the Redlich-Kister, Wilson, NRTL, UNIQUAC, UNIFAC, and Wisniak-Tamir relations. Most of th e models allow a good prediction of the activity coefficients of the t ernary system from those of the pertinent binary systems.
