Abstract
Objective: To explore the optimal technology for Benorilate synthesis.Method:When Acetylsalicylryl chloride was synthesized,DMF as catalysis was added,and Benorilate was obtained in the presence of Polyethylene glycol(PEG) phase transfer catalyst.Results:Benorilate was synthesized with an overall yield of 95%.Conclusion:The technology can shorten the time of reaction,with higher yield and lower cost.
