中文摘要 | 本研究是於一多相系統中,藉由RuO₂與KCl氧化還原雙媒子間接氧化Anthracene成Anthraquinone之電化學反應。探討通電量;RuO₂與KCl;電解質種類;Anthracene濃度;攪拌速率;KCl濃度;酸鹼度;電流密度與RuO₂濃度等因素對電氧化反應的影響。實驗結果証實生成Anthraquinone之最佳電流效率可達78%,並且影響電流效率之主要因素有通電量;RuO₂與KCl;電解質種類;Anthracene濃度;攪拌速率;KCl濃度及酸鹼度。此外,電流密度與RuO₂濃度對於電流效率影響較小。 |
英文摘要 | Indirect anodic oxidation of anthracene achieved by using both chloride anion and ruthenium cation redox double mediator in a multi phase system was studied. Factors affecting the current efficiency of anthraquinone were explored. The results revealed that the highest current efficiency of anthraquinone reached 78%. The current efficiency was mainly affected by the amount of electricity passed, the RuO₂ and double redox mediator, the kind of electrolyte used, the concentration of anthracene, the agitation rate, the concentration of KCl and the pH value. Further, the current efficiency was slightly affected by the anode current density and the concentration of RuO₂. |
