摘要：

Isobaric vapor-liquid equilibrium (VILE) data of the binary system maleic anhydride (MAN)+di-n-butylsebacate (DBS) at 2.67, 5.33 and 8.00 kPa are determined using the ebulliometric method. The saturated vapor pressures of pure DBS are also measured and Antoine constants are obtained. The measured equilibrium temperatures, pressures and feed compositions were used to obtain NRTL parameters and equilibrium liquid and vapor compositions. Moreover, vapor-liquid equilibrium data for the binary system are predicted from the universal quasi-chemical functionalgroup activity coefficients (UNIFAC) model. Predicted results are compared with those from the ebulliometric method, and good agreement is found. (c) 2008 Published by Elsevier B.V.
