For separation of the azeotrope of allyl alcohol and water, three extractive agents—isobutyl acetate, butyl acetate, and butyl propionate—were selected to extract allyl alcohol from the azeotrope. To recover the extractive agents by distillation, the isobaric vapor–liquid phase equilibrium (VLE) data for allyl alcohol + isobutyl acetate, allyl alcohol + butyl acetate, and allyl alcohol + butyl propionate were measured at 101.3 kPa. With the VLE data, there is no azeotrope formed in three systems. The consistency of the measured VLE data was validated by the Herington, infinite dilution, pure component consistency, and van Ness tests. Moreover, the Wilson, UNIQUAC, and NRTL models were used to fit the measured VLE data. All of the calculated results agreed with the VLE experimental data. Meanwhile, the parameters of the Wilson, UNIQUAC, and NRTL were regressed, which can be employed for the development and optimization of the separation process. Furthermore, the VLE data were predicted by the UNIFAC model for the three binary mixtures, and better prediction values were presented.

101.3 kPa下烯丙醇与乙酸异丁酯，乙酸丁酯和丙酸丁酯的二元体系等压蒸气-液体平衡的测量和相关
为了分离烯丙醇和水的共沸物，选择了三种萃取剂-乙酸异丁酯，乙酸丁酯和丙酸丁酯-从共沸物中萃取烯丙醇。为了通过蒸馏回收萃取剂，烯丙醇+乙酸异丁酯，烯丙醇+乙酸丁酯和烯丙醇+丙酸丁酯的等压汽液相平衡（VLE）数据为101.3 kPa。使用VLE数据，在三个系统中没有形成共沸物。测量的VLE数据的一致性通过Herington，无限稀释，纯组分一致性和van Ness测试进行了验证。此外，使用了Wilson，UNIQUAC和NRTL模型来拟合测得的VLE数据。所有计算结果均与VLE实验数据一致。同时，威尔逊（Wilson），UNIQUAC，对NRTL和NRTL进行了回归分析，可用于分离过程的开发和优化。此外，通过UNIFAC模型对三种二元混合物的VLE数据进行了预测，并给出了更好的预测值。
