摘　　要：介绍了直接电氧化法和间接电氧化法制取烟酸的原料及相应的电极反应,同时对直接电氧化法制取烟酸的电解槽、电极材料、离子交换膜及支持电解质等的研究进展进行了评述。直接电氧化法多采用Pt、PbO2和PbO2/Ti为阳极,Pb和Ni为阴极,离子交换膜为隔膜,电流效率可达70%。The raw materials and electrode reactions of direct and indirect electrochemical oxidation synthesis methods of nicotinic acid were introduced in this paper. Meantime, the research progress of cell,electrode materials,ion exchanging membrane and supported electrolysis in direct electrochemical oxidation synthesis methods of nicotinic acid were reviewed. In the direct electrochemical oxidation synthesis methods of nicotinic acid with Pt, PbO_2, PbO_2/Ti as anode, with Pb, Ni as cathode and with ion exchanging membrane as separated materials, the current efficiency is 70%.
