• 中文摘要： 本文探討在隔離式及槽式電解槽中,以銀(I)離子為氧化介質陽極氧化甲苯合成苯甲醛,有系統地改變各種操作條件,觀察其對生成苯甲醛電流效率的影響,藉此找出陽極氧化甲苯合成苯甲醛之最佳操作條件,實驗結果顯示:生成苯甲醛之電流效率隨銀(I)離子濃度,硝酸濃度及溫度之增加而增加,隨電流密度之增加而減少。在相同的電解操作條件下,槽式電解槽之電流效率約比隔離式電解槽之電流效率低5至20%。
• 英文摘要： The optimum operation conditions required for producing benzaldehyde from toluene via anodic oxidation in an undivided and divided cell were investigated. The factors which affect the current efficiency of producing benzaldehyde were obtained. The current efficiency of benzaldehyde was demonstrated by the results to be primarily dependent on temperature, current density, concentrations of Ag/sup +/ ion and nitric acid. The current efficiency in an undivided cell was 5-20% less than that in a divided cell.
