Phase equilibria in the systems 1-hexene plus benzene and 1-hexene plus ethyl 1,1-dimethylethyl ether plus benzene at 94.00 kPa

Consistent vapor-liquid equilibria data at 94.00 kPa have been determined f or the ternary system 1-hexene + ethyl 1,1-dimethylethyl ether + benzene an d for its constituent binary 1-hexene + benzene, in the temperature range 3 34-351 K. According to the experimental results, the systems exhibit slight positive deviations from ideal behavior and no azeotrope is present. The V LE data have been correlated with the mole fraction using the Redlich-Kiste r, 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.
