Process for the preparation of 4'-isobutylacetophenone

摘要

The present invention relates to a process for the preparation of 4'-isobutylacetophenone from isobutylbenzene which comprises reactions isobutyl benzene with acetic anhydride as an acylating agent in the presence of a zeolite beta catalyst at a temperature ranges between 60 to 165° C. for 2-12 h separating the catalyst by filtration from the reaction mixture and recovering the product by a conventional method.
