Abstract

Consistent vapor-liquid equilibria data at 94 kPa have been determined for the ternary system ethyl 1,1-dimethylethyl ether + cyclohexane + 2,2,4-trimethylpentane and for its constituent binary cyclohexane + 2,2,4-trimethylpentane, in the temperature range 343 to 369 K. According to the experimental results, the systems exhibit 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.
