摘要
以聚乙二醇（PEG）为相转移催化剂，采用液一液相转移催化的方法，由乙酰水杨酰氯和对乙酰氨基苯酚制得高产率的贝诺酯，且反应时间短、操作简便。同时，考察了不同分于量的PEG对产率的影响。
Benorylate was symthesized by phase-transfer catalysis from Scalicylic acid choorlde and acetaminophen with the yield of 97.0%.The synthesis was simple and rapid.Relationships between the yield and different moleCular weight PEC wer investigated.
