In this work, the isobaric vapor–liquid equilibrium (VLE) data for ethyl acetate + propyl acetate, ethyl acetate + propylene carbonate, and propyl acetate + propylene carbonate systems were measured at a pressure of 101.3 kPa by a modified Rose vapor recirculating-type equilibrium still. The experimental results show that no azeotrope was detected between the three binary systems. Two thermodynamic consistency tests of Herington and van Ness were employed to check the experimental data, respectively. The measured VLE data were correlated by Wilson, universal quasichemical, and nonrandom two-liquid models. The calculated root-mean-square deviation values of the equilibrium temperature and vapor phase mole fractions are not more than 1.07 and 0.0113, respectively. The relative volatilities were calculated and the deviations between the experimental data and Wilson model calculations were compared. All the correlated results are in good agreement with the measured data. Meanwhile, the binary interaction parameters were regressed by the three models for all the binary systems.

醋酸乙酯+醋酸丙酯，醋酸乙酯+碳酸丙烯酯和醋酸丙酯+碳酸丙烯酯的三元体系的等压汽液平衡
在这项工作中，采用改良的Rose蒸汽再循环型在101.3 kPa的压力下测量了乙酸乙酯+乙酸丙酯，乙酸乙酯+碳酸亚丙酯和乙酸丙酯+碳酸亚丙酯系统的等压蒸气-液体平衡（VLE）数据。平衡仍然。实验结果表明，在三个二元系统之间未检测到共沸物。用Herington和van Ness的两个热力学一致性测试分别检查了实验数据。测得的VLE数据通过Wilson，通用准化学和非随机两液模型进行关联。计算出的平衡温度和气相摩尔分数的均方根偏差值分别不大于1.07和0.0113。计算相对挥发度，比较实验数据与Wilson模型计算之间的偏差。所有相关结果均与实测数据吻合良好。同时，三个模型对所有二元系统的二元相互作用参数进行了回归。
