本研究的目的在於量測液液相平衡數據，以供程序設計使用。本實驗分別量測water＋methanol＋methyl oleate、water＋methanol＋methyl linoleate、glycerol＋methanol＋methyl oleate、glycerol＋methanol＋methyl linoleate、nonane＋benzene＋sulfolane、nonane＋toluene＋sulfolane以及nonane＋m-xylene＋sulfolane七組三成分在298.15 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與UNIQUAC兩種模式進行相平衡數據關聯，計算結果顯示UNIQUAC的關聯結果優於NRTL。本研究亦使用數種UNIFAC模式預測液液相平衡性質，計算結果顯示只有對含sulfolane的混合物系統有較佳的預測，但是對於其他的混合物系統則無法獲得令人滿意的結果。

The objective of this work is to measure the liquid-liquid equilibrium (LLE) data of specific ternary systems for process design purposes. The LLE data of seven ternary systems, including water + methanol + methyl oleate, water + methanol + methyl linoleate, glycerol + methanol + methyl oleate, glycerol + methanol + methyl linoleate, nonane + benzene + sulfolane, nonane + toluene + sulfolane and nonane + m-xylene + sulfolane were measured at temperatures ranging from 298.15 K to 318.15 K. In general, two-phase region became smaller as increase of temperature, but this effect is not significant.The NRTL model and the UNIQUAC model were used to correlate the phase equilibrium data. The UNIQUAC model was found to be better than the NRTL model. This study also used various vesions of the UNIFAC model to predict the LLE properties. Good predictions were obtained for nonane＋(benzene or toluene or m-xylene)＋sulfolane systems. Unfortanately, the results for other systems are unsatisfactory.
