采用循环伏安法和计时电流法研究了2，2，6，6-四甲基哌啶基-N-氧自由基（克里思）介导的电催化氧化制乙二醇的电化学行为.克里思在这两种电解质中的电化学氧化半波电位和电位分离都有不同的表现。首次报道了克里思介导的乙二醇电催化氧化反应，观察到该电催化氧化反应在二氯甲烷溶液中的起始电位大于在碳酸盐缓冲溶液中的起始电位，并由计时电流图计算出在碳酸盐缓冲溶液中的电催化氧化速率常数为1.63 × 103 L·mol-1·s-1，其是在二氯甲烷溶液中的40倍大。
2,2,6,6-Tetramethylpiperidinyl-N-oxyl (TEMPO) mediated electrocatalytic oxidation toward ethylene glycol was investigated as a function of electrolyte (aqueous carbonate buffer solution of pH 9.6 and dichloromethane solution with 2,6-lutidine as the base) by cyclic voltammetry and chronoamperometry. Both half-wave potentials and potential separations of electrochemical oxidation of TEMPO in these two electrolytes show differently. Electrocatalytic oxidation of ethylene glycol mediated by TEMPO was firstly reported here, it was observed the onset potential of this electrocatalytic oxidation reaction in dichloromethane solution is larger than that in carbonate buffer solution, moreover, electrocatalytic oxidation rate constant is calculated from chronoamperograms to be 1.63 × 103L·mol−1·s−1in carbonate aqueous buffer solution, which is forty times as large as that in dichloromethane solution.
