Abstract

New vapor-liquid equilibrium data have been obtained for the binary system methyl ethyl ketone-p-xylene at 760 mmHg to compare with previously reported data assumed to be thermodynamically Inconsistent. The system presents slight positive deviations from Ideal solution behavior. The activity coefficients are well correlated by a three-constant Redlich-Kister equation and by the Wilson equation. Boiling points are adequately described by a four-constant equation, and vapor composition is very accurately predicted by the UNIFAC method.
