| 摘 要： | 测定了常压下20、30、40、50℃时醋酸甲酯 水二元体系及醋酸甲酯 甲醇 水三元体系的液液平衡(LLE)数据,并与文献中已有的醋酸甲酯 水的液液平衡数据进行比较,证明了测定方法的可靠性。采用二元与三元液液平衡数据相结合的关联方法,并用NRTL和UNIQUAC模型对所测数据进行了热力学关联,得出了相应的模型参数。用该模型对三元体系进行计算,结果令人满意。用VisualBasic6.0语言开发了液液相平衡关联软件,可方便地用于二元和三元液液相平衡的计算。

| Abstract: | LLE (liquid-liquid equilibrium) data were determined for the methyl acetate-methanol-water ternary system and the related methyl acetate-water binary system at 20, 30, 40 and 50 ℃ under atmospheric pressure. The experimentally determined LLE data for the binary system were in satisfactory agreement with available literature data. The experimental data were correlated by the activity coefficient models of NRTL and UNIQUAC, and the comparison between calculated and experimental data shows good agreement. The software of LLE Correlation and Calculation was developed by Visual Basic 6.0, which can correlate and calculate LLE data of the binary and ternary system conveniently. |
