| Abstract: | 1,4,7,10,13,16-Hexaoxacyclooctadecane is used as phase transfer catalyst,and N,N-Diethylaniline is synthesized by reaction of aniline with bromoethane under atmospheric pressure.The factors affecting the yield of the target product are studied.The optimal reaction conditions are molar ratio 1∶1.5 of aniline to bromoethane,35×10-2 in 45 mL sodium hydroxide solution,0.8 g catalyst at 55℃ for 4h under normal atmosphere.The yield of the N,N-diethylaniline is 73.1%. |
