摘要：

Isobaric vapor-liquid equilibrium (VLE) data for the binary system of maleic anhydride(MAN) + dimethyl phthalate (DMP) at 4.00, 8.00 and 12.00 kPa were determined by using the ebulliometric method. Also, saturated vapor pressures of pure DMP were measured and Antoine constants were obtained. The parameters of the NRTL:model for the binary system were obtained by calculating the equilibrium compositions of the liquid and vapor phase with the experimental equilibrium temperatures, pressures and feed compositions. Moreover, VLE data for the binary system were predicted by use of the UNIFAC model. The predicted results were compared with those from the ebulliometric method, and showed a good agreement.
