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PbO2/Ti电极上的电极反应,发现PbO2/Ti电极对生成烟酸有电催化作用.通过高效液相色谱分析,进一步考察了各种因素对电流效率的影响.

关键词: 3-甲基吡啶, 电氧化, 烟酸

Abstract: In an electrolytical cell with cation exchange membrane, the electrooxidatione reactions of 3-picoline on Pt or PbO2/Ti electrodes were examined with steady state polarization curves. It was found that PbO2/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.

Key words: 3-Picoline, Electrooxidation, Nicotinic acid
