Abstract

Consistent vapor-liquid equilibrium data at 94.00 kPa have been determined for the ternary system 1-hexene + ethyl 1,1-dimethylethyl ether + heptane and for its constituent binary 1-hexene + heptane, in the temperature range 334 to 369 K. According to the experimental results the ternary system 1-hexene + ethyl 1,1-dimethylethyl ether + heptane exhibits moderate positive deviations from ideal behavior. The binary system 1-hexene + heptane exhibits slight negative deviations from ideal behavior. None of the systems present an azeotrope. The vapor liquid equilibrium data have been correlated with the mole fraction using the Redlich-Kister, Wilson, NRTL, UNIQUAC, and Tamir relations. These models, in addition to UNIFAC, allow good prediction of the VLE properties of the ternary system from those of the pertinent binary systems.
