摘要：
Consistent vapor-liquid equilibria (VLE) were determined for the ternary system ethanol + methylcyclohexane + p-xylene and the three binary subsystems at 101.3 kPa at temperatures in the range from 345 to 408 K. The binary systems exhibit positive deviation from ideal behavior, and the system ethanol + methylcyclohexane presents a minimum-boiling-point azeotrope. The VLE data have been correlated by the Wilson, NRTL, and UNIQUAC equations. The ternary system does not present an azeotrope and is well predicted from binary interaction parameters.
