Abstract Experimental analysis of vapour-liquid phase equilibrium (VLE) for five binary pairs of diethyl carbonate (DEC) with methyl acetate, ethyl acetate, isopropyl acetate, n-butyl acetate and isoamyl acetate was carried out in this study. VLE data were generated experimentally at local atmospheric pressure of 95 kPa in a glass dynamic recirculation still. Reliability of data was checked with the thermodynamic consistency tests by Van Ness, infinite dilution, pure component and mean absolute deviation test. Experimental data was found to be thermodynamically consistent with all tests and data was regressed with Wilson, NRTL and UNIQUAC activity coefficient models to determine binary interaction parameters. Binary pair of DEC with n-butyl acetate has shown azeotropic behaviour with minimum boiling azeotrope and a close-boiling behaviour through-out the composition range. No azeotropic behaviour was observed for the rest of the binary pairs.

碳酸二乙酯与乙酸甲酯、乙酯、异丙酯、正丁酯和异戊酯在 95 kPa 的二元体系气液相平衡的实验分析

摘要 本研究对碳酸二乙酯(DEC)与乙酸甲酯、乙酸乙酯、乙酸异丙酯、乙酸正丁酯和乙酸异戊酯的五个二元对的汽液相平衡(VLE)进行了实验分析。VLE 数据是在 95 kPa 的当地大气压下在玻璃动态再循环蒸馏器中通过实验生成的。数据的可靠性通过 Van Ness 的热力学一致性测试、无限稀释、纯组分和平均绝对偏差测试进行检查。发现实验数据在热力学上与所有测试一致，并且使用 Wilson、NRTL 和 UNIQUAC 活动系数模型对数据进行回归，以确定二元相互作用参数。DEC 与乙酸正丁酯的二元对在整个组成范围内显示出具有最小沸点共沸物的共沸行为和接近沸点行为。对于其余的二元对，没有观察到共沸行为。
