摘　　要：以2-甲基吡啶为原料,用电化学方法合成了2-吡啶甲酸.研究了反应温度、硫酸浓度、反应物2-甲基吡啶浓度和阳极电位对选择性和电流效率的影响.结果表明,在最佳反应条件下,以电化学方法合成2-吡啶甲酸的选择性高达95.3%,电流效率可达到45.3%.2-Pyridinecarboxylic acid was prepared by electrooxidation of 2-methylpyridine. The analysis and isolation of the product were carried out. The influences of reaction conditions, such as the temperature, the anodic potential, the concentrations of sulfuric acid and 2-methylpyridine on the selectivity and the current ef- ficiency were studied. Under the optimum conditions, the highest selectivity is 95.3% and the current efficiency is 45. 3%.
