摘要
Isobaric vapor–liquid equilibrium (VLE) data for the binary system maleic anhydride (MAN)+di-n-butyl phthalate (DBP) at 2.67, 5.33 and 8.00kPa were determined using the ebulliometric method. The parameters of the NRTL model for the binary system were obtained by calculating 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. Predicted results were compared with those from the ebulliometric method, and showed good agreement.
