本研究使用一套具有視窗平衡釜的靜態式相平衡量測裝置，量取恆溫下之汽液相平衡與汽液液相平衡數據，其量測溫度介於318.15 K至363.15 K。本研究量測丙二醇甲醚+丙二醇甲醚丙酸酯雙成分系統的汽液平衡數據，以及水+丙二醇甲醚丙酸酯與水+丙二醇甲醚+丙二醇甲醚丙酸酯的汽液液平衡數據。水+丙二醇甲醚丙酸酯汽液液平衡數據丙二醇甲醚+丙二醇甲醚丙酸酯汽液平衡系統數據均能以NRTL-HOC及UNIQUAC-HOC模式搭配溫度線性關係的參數，獲得良好的關聯結果。使用由雙成分系統的汽液平衡或汽液液平衡數據所訂定的參數，無法準確地估算水+丙二醇甲醚+丙二醇甲醚丙酸酯三成分系統的汽液液平衡性質。本研究所量得的三成分汽液液平衡數據也用於檢驗多種版本之UNIFAC模式的合適性。以同時調整NRTL-HOC及UNIQUAC-HOC模式中的模式參數的方式，可大幅地改善對水+丙二醇甲醚+丙二醇甲醚丙酸酯三成分系統之汽液液平衡性質的描述。

A static-type apparatus equipped with a visual cell was utilized in the present study to measure isothermal vapor-liquid equilibrium (VLE) and vapor-liquid-liquid equilibrium (VLLE) data over a temperature range of 318.15 K to 363.15 K. The VLE data were determined experimentally for the binary systems of propylene glycol monomethyl ether (PGME) + propylene glycol monomethyl ether propionate (PGMEP). The VLLE data were also measured for water + PGMEP and water + PGME + PGMEP. The experimental data of the binary systems can be correlated well with the NRTL-HOC and the UNIQUAC-HOC models by using linearly temperature-dependent parameters. The ternary VLLE properties can not be estimated accurately by using the parameters determined from the phase equilibrium data of the constituent binaries. The ternary VLLE data were also used to test the validity of various versions of the UNIFAC model. The representation of the ternary VLLE properties is substantially improved as the parameters of the NRTL and the UNIQUAC models are determined simultaneously from the ternary VLLE data.
