ABSTRACT
Consistent vapor-liquid equilibria (VLE) was determined for the ternary system ethanol + methylcyclohexane + p-xylene and the three binary subsystems at 101.3 kPa at temperatures in the range 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.
