本研究為探討鹽效應在乙酸正丁酯-正丁醇-水三成份系統之影響,因此在298.15K下,以乙酸正丁酯-正丁醇-水系統,分別在飽和氯化鈉、氯化鉀、溴化鈉與溴化鉀濃度下,進行液液平衡實驗,並以TTK-Wilson活性係數模式作理論模擬。發現含電解質平衡系統中,電解質使得水相中存在的作用力發生變化,正離子的電荷密度大者水合較佳,負離子的極化現象佳者與水的作用力較強,以TTK-Wilson活性係數模式作理論模擬結果與實驗的結果相符合。

The salt effect on ternary system of n-butyl acetate / n-butanol / water mixture was investigated. The molecular or ionic interaction in the water phase has been changed when the Liquid-Liquid Equilibria (LLE) has been achieved under the condition of which containing saturate NaCl or KCl or NaBr or KBr at 298.15K. The solvation of cation in water is better as electronic density of cation is larger and the solvation of anion is better when polarity of anion is stronger. The simulation using TTK-Wilson activity coefficient model also presented. The mole fraction of each component in different phase of Liquid-Liquid Equilibria (LLE) experiments were in good agreement as the result of simulation using TTK-Wilson activity coefficient model.
