Anodic Oxidation of Cyclohexanone on Lead Dioxide Electrode in Aqueous Sulfuric Acid Solution

The electrolytic behavior of cyclohexanone was examined by potentiometry with rotating disk electrode as well as by product analyses. The reaction was activation controlled and the reaction orders were first with respect to cyclohexanone and zero for proton. Cyclohexanone reacted by approximately 6...

Summary:The electrolytic behavior of cyclohexanone was examined by potentiometry with rotating disk electrode as well as by product analyses. The reaction was activation controlled and the reaction orders were first with respect to cyclohexanone and zero for proton. Cyclohexanone reacted by approximately 6 electrons to give adipic acid mainly which accumulated proportionally to the electricity consumed. Changes in temperature, proton concentration, and current density resulted in only minor effects on the reaction. In neutral solution, however, the oxidation was suppressed and oxygen evolution dominated. Other electrode materials such as Pt, graphite, RuO2, and PtO2 were inactive. The chemical oxidation with PbO2 itself did not occur. From these facts, reaction mechanism was discussed.
