摘要
本研究之主要重點主要如下：（1）水/正十二烷/C4E1、水/正十四烷/C4E1烷三成分系統於25℃-45℃下之液-液相平衡量測；（2）以UNIQUAC MODEL迴歸實驗數據，並將所得理論曲線與實驗值比較。其中非離子型界面活性劑（CiEj）為CH3(CH2)i-1(OCH2CH2)jOH的簡寫，"i"代表疏水基的非極性碳氫鏈數，"j"代表親水基數。
本實驗以氣體層析儀與Karl-Fischer水分測定儀來分析達到相平衡時組成，其校正誤差小於0.5﹪。於實驗數據與model迴歸上，我們以UNIQUAC 方程式求出水/正十二烷/C4E1與水/正十四烷/C4E1三成分系統之作用力參數，並以此參數作Flash Calculation得其理論上的平衡組成；對於只有兩相平衡的系統,可以發現在界面活性劑含量較低時有比較大的誤差,但隨著界面活性劑的增加,理論缚線與實驗數據有越來越吻合的趨勢,對於具有三相區的系統,可以藉由解單一三相共存區的數據得其可代表整個相行為的作用力參數。

ABSTRACT
In this study; The liquid-liquid equilibrium measurements of two ternary system: water/ dodecane/ C4E1 and water/ tertradecane/ C4E1 at 25~45℃ were performed. Then doing the experimental data were numberically regressed with UNIQUAC MODEL. The nonionic surfactant CiEj is the abbreviation of CH3 (CH2)i-1 (OCH2CH2 )jOH, where "i" means the number of nonpolar hydrocarbon chains of hydrophobic groups and "j" is the number of hydrophilic groups.
Gas chromatography method was applied to determine the composition of these liquid-liquid equilibrium systems, and the calibration error is within 0.5. The UNUQUAC interaction parameters were numerically regressed by minimizing the error ofcomposition. For the system with three- liquid- phase- coexisting, all the six interaction parameters can be solved directly from the compositions of three-liquid phase. The detail of regression procedure is discussed.
