| Abstract: | Using polyethylene glycol 10000 as phase transfer catalyst,N,N-Diethylaniline is synthesized by the reaction of aniline with bromoethane under atmospheric pressure.The factors affecting the yield of the target product have been studied.The optimal conditions are：the molar ratio of aniline to bromoethane is 1∶1.50;40×10-2 sodium hydroxide solution,30mL;the amount of catalyst,1.00g;reaction temperature,75℃;reaction time,6h;under normal atmosphere.The yield of N,N-Diethylaniline is 85.6%. |
