摘　　要：在常压下向苯胺/十六烷基三甲基溴化铵/正丁醇/水微乳体系中滴加溴乙烷合成N,N-二乙基苯胺。研究了各种因素对目的产物产率的影响,其优化工艺条件为反应温度50℃,反应时间5小时,溴乙烷与苯胺的摩尔比为1.75∶1,氢氧化钠加入量为4.0g。N,N-二乙基苯胺产率可达70.1%。N, N-Diethylaniline was synthesized from aniline and bromoethane in C6 H5 NH2/CTAB/C4H9OH/H2O microemulsion under normal atmosphere. Various factors affecting the yield of N, N-diethylaniline were discussed. The optimum technological conditions were reaction temperature 50℃ ,reaction time 5 hour, mole ratio of bromoethane to aniline 1.75 and mass of NaOH 4. 0g, the yield of N, N-diethylaniline was 70. 1%.
