摘　　要：以三乙胺、氯化苄为反应物,异丙醇为溶剂,经过季铵化反应合成了相转移催化剂三乙基苄基氯化铵(BTEAC),收率达到80%以上。将其应用于芳烃的氧化和亲核取代反应,实验结果表明,加入相转移催化剂BTEAC的芳烃氧化反应,收率超过69%,较不加催化剂的反应收率提高了28%;加入相转移催化剂BTEAC的亲和取代反应,收率可达到92%以上,较不加催化剂的反应收率提高了10%。Triethyl benzyl ammonium chloride was synthesized from three experiments, ethyl in isopropanol, the yield reached more than 80%. Applies the phase transfer in aromatics oxidation and nueleophilic substitution reaction, the results showed that the yield up to 69% in aromatics oxidation reaction, 28% more than that not the catalyst reaction; while the yield is 92% in the nucleophilic substitution reaction and 10% more than not the catalyst reaction.
