本研究採用一套靜態式液相循環的相平衡裝置，量測苯甲酸甲酯＋苯甲酸、苯甲酸乙酯＋苯甲酸與水＋苯甲酸三組雙成份混合物在413.15 K∼453.15 K間之汽液平衡數據，實驗結果顯示這三組雙成份系統皆無共沸物產生。這些汽液平衡數據為設計以反應性蒸餾法分離水／乙醇共沸物之程序所需。
所量取之雙成份汽液平衡數據可分別用NRTL與UNIQUAC模式準確地關聯，本研究並以量測之結果檢驗兩種不同版本之UNIFAC模式，計算結果顯示， 1982年版的UNIFAC模式對苯甲酸甲酯＋苯甲酸與苯甲酸乙酯＋苯甲酸系統能獲得較佳的預測值。

A static-type apparatus with a liquid-phase circulation loop was used to measure isothermal vapor-liquid equilibrium ( VLE ) data for the binary systems of methyl benzoate + benzoic acid, ethyl benzoate + benzoic acid, and water + benzoic acid at temperatures from 413.15 K to 453.15 K. The experimental results exhibited no azeotrope formation. These VLE data are needed for design of separation process of azeotropic water/ethanol mixture with reactive distillation method.
The binary VLE data were correlated satisfactorily with the NRTL and the UNIQUAC models, respectively. These VLE data were also used to test the two versions of UNIFAC model. The calculated results showed that the version of 1982 (UNIFAC-82) yielded better prediction for methyl benzoate + benzoic acid and ethyl benzoate + benzoic acid systems.
