Abstract

For the para-xylene-meta-xylene system, bubble points were precisely measured at atmospheric pressure and vapor-liquid equilibrium data were calculated using the Wilson equation. Values of the Wilson parameters δ12 ancJ δ21 were determined to minimize the sum of squares of deviations in the bubble points for all data points, and values of 0.9812 and 1.0196, respectively, were obtained. The average deviation of the present equilibrium data from those of ideal solution was within 0.00005 mole fraction in vapor composition.
