摘　　要：在有阳离子交换膜的电解槽内 ,通过稳态极化曲线测量 ,考察了 3 -甲基吡啶在 Pt电极和 Pb O2 / Ti电极上的电极反应 ,发现 Pb O2 / Ti电极对生成烟酸有电催化作用 .通过高效液相色谱分析 。In an electrolytical cell with cation exchange membrane, the electrooxidatione reactions of 3-picoline on Pt or PbO_2/Ti electrodes were examined with steady state polarization curves. It was found that PbO_2/Ti electrode possesses electrocatalysis activity for synthesizing nicotinic acid. The effects of various factors on current efficiency were also examined by the product analysis with HPLC.
