Abstract
In order to study the synthesis method of 2-hydroxy-4-methyl benzoic acid,this experiment adopts acetone and ethyl formate to synthesize formyl acetone.2-hydroxy-4-methyl benzoic acid has been synthesized by formyl acetone and acetoacetic ester.The structure of the ultimate product has been identified by three ways including IR,MS and ~(1)HNMR.The best synthetic condition has been chosen by repeated test,and because introducing pH gradient separation the synthetic route has been simplified.
