本研究的目的在於量測液液相平衡數據，以供模擬與設計反應性蒸餾塔時使用。本實驗分別量測水-丙烯酸-丙烯酸丁酯、水-正丁醇-丙烯酸丁酯、水-正丁醇-丙烯酸丁酯、水-乙醇-丙烯酸乙酯，以及水-丙烯酸-丙烯酸乙酯五組三成分在283.15 K~318.15 K之溫度範圍下液液相平衡數據。當溫度上升時，所有系統的兩相區變小；然而溫度效應並不明顯。本研究使用NRTL-HOC與UNIQUAC-HOC兩種模式進行相平衡數據關聯，計算結果顯示UNIQUAC-HOC的關聯結果優於NRTL-HOC。本研究亦使用數種UNIFAC模式進行液液相平衡預測，但結果都不佳。

The objective of this work is to experimentally deterimine the liquid-liquid equilibrium (LLE) data for simulation and design of reactive distillation tower.The LLE data of five ternary systems, including water + acrylic acid + n-butyl acrylate, water + n-butanol + n-butyl acrylate, water + acrylic acid + n-butanol, water + ethanol + ethyl acrylate and water + acrylic acid + ethyl acrylate were measured at temperatures ranging from 283.15 K ~ 318.15 K. When temperature rises, two-phase region of all systems would become smaller, but this effect is not apparaent.The NRTL-HOC model and the UNIQUAC-HOC model were used for the prediction of phase equilibrium behavior. The UNIQUAC-HOC model is found to be better than the NRTL-HOC model. This study also used various vesion of the UNIFAC model to predict the new data, but the results were not as good.
