| 摘 要： | 利用改进的沸点仪测定了顺酐-癸二酸二丁酯二元体系在413.15, 433.15和453.15 K下的等温气液平衡数据以及纯癸二酸二丁酯和顺酐的饱和蒸气压数据. 通过与文献值对比, 验证了此方法的可靠性. 同时, 将实验数据回归得到了纯癸二酸二丁酯和顺酐的Antoine常数. 利用NRTL方程进行了气液平衡数据的关联推算, 得到了顺酐-癸二酸二丁酯二元体系的NRTL模型参数. 利用UNIFAC基团贡献法对实验数据进行了预测, 其结果与实验值及运用NRTL方程拟合的结果吻合较好.

| Abstract: | Vapor-liquid equilibrium(VLE) data for maleic anhydride(MAN) and its absorption solvents are important for developing and researching the MAN production process.Isothermal VLE data for MAN and di-n-butylsebacate(DBS) binary system at 413.15,433.15 and 453.15 K were determined with a modified ebulliometer in this work.Saturated pressure of pure DBS and MAN were measured and their Antoine constants were obtained.The experimental results were correlated and calculated using the NRTL model.The UNIFAC model was ... |
