Abstract: In an electrolytic cell with proton exchange membrane as the diaphragm, it was found from the electrooxidation of 3-picoline at a PbO2 electrode in acetone/water mixed solvents that the current density at the same anode potential not only increases remarkably, but also the selectivity and the current efficiency of electrooxidation from 3\|picoline to nicotinic acid increase obviously compared with the pure water as the solvent. Electrooxidation conditions of 3-picoline in acetone/water mixed solvents was studied, and the selectivity and the current efficiency under various conditions were compared.

Key words: 3-Picoline, Acetone, Nicotinic acid, Electrooxidation
