N2 - Isobaric vapor-Liquid equilibrium (VLE) data at 94.00 kPa have been determined for the ternary system 1-hexene + ethyl 1,1-dimethylethyl ether + benzene and for its constituent binary system 1-hexene + 2,2,4-trimethylpentane (isooctane), in the temperature range 335 to 360 K. According to the experimental results, the system 1-hexene + 2,2,4-trimethylpentane exhibits ideal behavior. The ternary system exhibits slight positive deviations from ideal behavior, and no azeotrope is present. The VLE data have been correlated with the mole fraction using the Redlich-Kister, Wilson, NRTL, UNIQUAC, and Wisniak-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.
