摘　　要：在质子交换膜为隔膜的电解槽内,以丙酮、乙腈和2-丁酮与水分别构成混合溶剂体系,通过循环伏安和恒电位电解实验,探索了3-甲基吡啶在混合溶剂中在PbO2电极上的电氧化条件,并与纯水溶剂的情况相比,研究了氧化电流密度及生成烟酸的选择性和电流效率的变化.In an electrolytic cell with proton exchange membrane as a diaphragm, the electrooxidation conditions of 3-picoline at the PbO2 electrode were studied by cyclic voltammetry and potentiostatic electrolysis in acetone/water,acetonitrile/water and 2-butanone/water mixed solvents, respectively. In comparision with pure water as solvent, the current density of anode oxidation, the selectivity,and the current efficiency of producing nicotinic acid were changed in organic/water mixed solvents.
