PROCESS FOR THE PREPARATION OF AROMATIC BETA-DIKETONES

摘要

A process for the preparation of aromatic beta-diketones having the structural formula (see formula I) by the reaction of an acetophenone and a molar excess of an alphatic ester or an ester of benzoic acid in the presence of sodium alkoxide condensation agent in an aromatic hydrocarbon solvent. Also disclosed is a method of recycling the solvent and excess ester reactant after separation of the aromatic beta-diketone product.
