Physics and Chemistry of Liquids, 2001

Consistent vapor-liquid equilibria (VLE) at 94.00 kPa has been determined for the ternary system ethyl 1,1-dimethylethyl ether + 2,2,4-trimethylpentane + methylcyclohexane and the two constituent binaries ethyl 1,1-dimethylethyl ether + methylcyclohexane and 2,2,4-trimethylpentane + methylcyclohexane in the temperature range from 343 to 371 K. In addition, vapor pressures have been measured for methylcyclohexane from 331 to 374 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 composition 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.

Physics and Chemistry of Liquids, 2000

Vapor-liquid equilibrium at 94 kPa has been determined for the ternary system methyl 1,1-dimethylethyl ether (MTBE) + hexane + octane. The system deviates positively from ideality, and no azeotrope is present.

Fluid Phase Equilibria, 1999

Consistent vapor–liquid equilibrium data at 94 kPa have been determined for the ternary system hexane+ethyl 1,1-dimethylethyl ether+heptane.
