本研究之主要重點有三：（1）水/叔戊醇及水/C6E2兩成分系統於20-40℃下之液-液相平衡量測（2）水/叔戊醇/C4E2、水/叔戊醇/C6E2三成分系統於20-40℃下之液-液相平衡量測；（3）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。
在實驗的操作部分，本研究以氣體層析儀來分析相平衡組成，其校正誤差小於1﹪。於實驗數據處理上，我們以UNIQUAC 方程式求出水/叔戊醇及水/C6E2兩成分系統之作用力參數，以此所得的平衡組成計算值其平均誤差皆在0.03﹪以內；而對於水/叔戊醇/C4E2及水/叔戊醇/C6E2三成分系統，我們以實驗所得之平衡縛線迴歸UNIQUAC作用力參數，之後再以此參數求得理論之雙節曲線及平衡縛線，並計算平衡縛線理論值與實驗值之誤差，雖然最後結果富水相組成之偏差頗大，但對於富醇相，則仍具一定之準確性。

There are three main tasks in this study：（1）The liquid-liquid equilibrium measurements of water/2-methyl-2-butanol and water/C6E2 binary systems at 20-40℃（2）The liquid-liquid equilibrium measurements of water/2-methyl-2-butanol/C4E2 and water/2-methyl-2-butanol/C6E2 ternary systems at 20-40℃（3） Doing experimental data regression by UNIQUAC MODEL and then comparing the differences between theoretical values and experimental data. 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.
In this study, we determine the composition of these liquid-liquid equilibrium systems by gas chromatography method, and the calibration error is within 1﹪. Then we calculate the UNIQUAC MODEL interaction parameters of water/2-methyl-2-butanol and water/C6E2 binary systems, and the average error of the calculated values of equilibrium compositions is within 0.03﹪; In addition, we use experimental tie lines to do the regression of UNIQUAC interaction parameters in water/2-methyl-2-butanol/C4E2 and water/2-methyl-2-butanol/C6E2 ter-nary systems. We can find the theoretical binodal curves and equilibrium tie lines by these parameters, and calculate the error between the theoretical compositions of equilibrium tie lines and experimental data. Although there exists a large deviation in the aqueous phase, but in the alcohol rich phase, we have a good agreement with experimental data.
