Phase equilibria in the systems cyclohexane+2,2,4-trimethylpentane and ethyl 1,1-dimethylethyl ether plus cyclohexane+2,2,4-trimethylpentane at 94.00kPa

Consistent vapor-liquid equilibria data at 94 kPa have been determined for the ternary system ethyl 1,1-dimethylethyl ether + cyclohexane + 2,2,4-trim ethylpentane and for its constituent binary cyclohexane + 2,2,4-trimethylpe ntane, in the temperature range 343 to 369 K. According to the experimental results, the systems exhibit slight positive deviations from ideal behavio r and no azeotrope is present. The VLE data have been correlated with the m ole fraction using the Redlich-Kister, Wilson, NRTL, UNIQUAC, and Wisniak-T amir relations. These models, in addition to UNIFAC, allow good prediction of the VLE properties of the ternary system from those of the pertinent bin ary systems.
