【摘要】 研究了在阳极液中加入不同类型和不同浓度表面活性剂对3-甲基吡啶电氧化的影响.结果表明,十六烷基三甲基溴化铵、脂肪醇聚氧乙烯醚硫酸钠、十二烷基苯磺酸钠、十二烷基二甲基甜菜碱和山梨醇酐单硬脂酸酯的胶团对3-甲基吡啶电氧化有明显的促进作用.实验结果还表明,在低浓度的硫酸为支持电解质阳极液中加入表面活性剂与不加表面活性剂相比,3-甲基吡啶电氧化制取烟酸的选择性和电流效率明显提高.更多还原

【Abstract】 The effects of surfactants with different concentrations on the electrooxidation of 3-picoline were extensively investigated via the cyclic voltammetry curves.The results indicate that the current density are evidently enhanced in electrooxidation with cetyltrimethyl ammonium bromide,sodium fatty alcohol ether sulfate,sodium dodecyl benzene sulfonate,N,N-dimethyl-N-dodecyl acetate sodium and sorbitan monostearate.So,it is probably synthesized nicotinic acid from 3-picoline in the lower concentration sulfuric acid with surfactants.The product selectivity and the current efficiency under the specific conditions are enhanced than no surfactants in the electrolyte.更多还原
