It is an alkane-based compound, and particularly preferred is "cyclohexane".

- an intermediate scavenger In the process of converting a starting material into a reaction intermediate, an intermediate scavenger often also undergoes a decomposition reaction at the same time, hindering such a reaction. That is, when the starting material is converted into an electrolytic reaction intermediate by an electrolytic reaction at the anode, the intermediate scavenger coexisting in the system is simultaneously oxidized and decomposed at the anode. This is illustrated in FIG. In addition, the electrolytic reaction intermediate is reduced at the right cathode shown in FIG. 3 and often returns to the starting material. In the past, separation of selective ion permeable membranes was provided in the electrolytic cell to solve the second problem.
