Abstract
Isobaric vapor-liquid equilibrium (VLE) data for the binary system maleic anhydride (MAN)Â +Â di-isobutyl hexahydrophthalate (DIBE) at 2.67, 5.33 and 8.00Â kPa were measured with a modified ebulliometer. Also, saturated vapor pressures of pure DIBE were measured and Antoine constants were obtained. These data were used to calculate equilibrium vapor and liquid compositions for this binary system using the NRTL model. Prediction of the VLE was done with the universal quasi-chemical functional-group activity coefficients (UNIFAC) model. The predicted results generally agree with those from experiment.
