摘　　要：介绍了N-乙基咔唑的几种合成方法:一般合成法、催化合成法和微波诱导催化合成法,比较3种方法得出,相转移催化法是合成N-乙基咔唑的最佳途径。N-ethyl carbazole is a very important dye intermediates,which can be used to synthesize the dye of sulphur vat blue GNX and the pigment of violet RL and the dye of carbon,etc.This article had introduced the synthesis of N-ethyl carbazole through several methods such as general synthesis,phase transfer catalysis and microwave induced catalytic synthesis.Compared the three methods above,phase transfer catalysis was the best way to synthesize the N-ethyl carbazole.
