中文摘要 | 本文利用萃取滴定方法測量在油相(二氯甲烷或氯苯)與純水中之四級鹽類之濃 度,並計算相關之熱力學參數-真實萃取常數,分配常數,水相之解離常數,平均活性係 數,及各項常數在兩相中之自由能。在四級鹽類為高濃度,即平均活性係數並非等於1時 ,建立一數學方法計算上迷之各項熱力學參數。 |
英文摘要 | In this study, concentration of quaternary salt in a dichloromethane (or chlorobenzene ) /water system were measured by extractive-titration method. Relevant thermodynamic data of these systems were also calculated. The true extraction constant, distribution constant, dissociation constant in the aqueous phase, mean activity coefficient, and free energies of the true extraction constant, distribution constant, and dissociation constant were obtained as well. A numerical model based on the concept of varied activity coefficient was designed to calculate the distribution constants and dissociation constants of these quaternary salts. lts. |
