Isobaric vapor–liquid equilibria of tert-butanol + chlorobenzene and tert-butyl acetate + chlorobenzene binary systems and the tert-butanol + tert-butyl acetate + chlorobenzene ternary system at 101.33 kPa were measured using a circulation VLE still. The data of binary systems passed the thermodynamic consistency test of the Herington method and the Van Ness point test, and the experimental data of the ternary system also passed the Wisniak consistency test. These binary systems’ VLE data were fitted by the Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) activity coefficient models with minor deviations. Furthermore, the obtained binary interaction parameters from the binary systems were used to predict the VLE behavior of the tert-butanol + tert-butyl acetate + chlorobenzene ternary system. The rmsd of vapor and the temperature between the experimental and predicted values for the ternary system were smaller than 0.0304 and 0.81K, respectively. The results indicated that the relative volatility between tert-butanol and tert-butyl acetate obviously increased when adding chlorobenzene as a solvent. Thus, chlorobenzene is a promising solvent for the separation of the tert-butanol and tert-butyl acetate mixture system by extractive distillation.

叔丁醇+乙酸叔丁酯+氯苯的二元和三元体系的等压蒸气-液体平衡在101.33 kPa

叔丁醇+氯苯和乙酸叔丁酯+氯苯二元体系以及叔丁醇+叔丁醇的等压气液平衡使用循环VLE蒸馏器在101.33kPa下测量乙酸丁酯+氯苯三元体系。二元系统的数据通过了Herington方法的热力学一致性测试和Van Ness点测试，三元系统的实验数据也通过了Wisniak一致性测试。这些二元系统的VLE数据由Wilson，非随机二液（NRTL）和通用拟化学（UNIQUAC）活度系数模型拟合而成，并具有较小的偏差。此外，从二进制系统所获得的二元相互作用参数用于预测的VLE行为叔丁醇+叔乙酸丁酯+氯苯三元体系。三元系统的蒸气均方根值和实验值与预测值之间的温度分别小于0.0304和0.81K。结果表明，以氯苯为溶剂，叔丁醇与乙酸叔丁酯的相对挥发度明显增加。因此，氯苯是用于通过萃取蒸馏分离叔丁醇和乙酸叔丁酯混合物系统的有前途的溶剂。
