| Abstract: | 7-Hydroxy-4-methyl coumarin was synthesized by PEG-supported sulfuric acid from ethyl acetoacetate and resorcinol under free-solvent condition.It is found that the method couples the advantages of reactive condition and simple manipulation.Moreover,the activity of catalyst has not been reduced significantly after the recycle of six runs. |
