摘　　要：以咔唑和甲基丁炔醇为原料,反应生成N-乙烯基咔唑,反应液经过进一步处理得到纯品N-乙烯基咔唑。考察了反应用溶剂、反应温度及反应时间对N-乙烯基咔唑收率的影响。结果表明:合成产物的最佳溶剂是DMSO,最佳反应温度为140℃,最佳反应时间为12 h。产物经FTIR、^(1)HNMR、^(13)CNMR进行结构表征。N-乙烯基咔唑的液相色谱纯度>99.5%,气相色谱纯度>99.5%,熔点64℃,总产率85%,合成产物可作为电子级化学品使用。N-vinyl carbazole was produced by reaction from carbazole and methyl butanediol, and the pure N-vinyl carbazole was obtained by further treatment of reaction liquid.The effects of reaction solvent, reaction temperature and reaction time on the yield of N-vinyl carbazole were investigated. The results showed that the best solvent for the synthetic product was DMSO, the best reaction temperature was 150 ℃, and the best reaction time was 12 h. The structure of the product was characterized by FTIR, ^(1)H NMR and ^(13)CNMR.The liquid chromatography purity of n-vinyl carbazole was >99.5%, the gas chromatography purity was > 99.5%, the melting point was 64 ℃, the total yield was 85 %, the synthetic products can be used as electronic grade chemicals.
