Method for producing aromatic beta-diketones |
| abstract |
(57) [Summary] [Objective] To provide a method for producing a high-purity beta-diketone with high purity. A method for producing an aromatic beta-diketone by reacting acetophenone and a molar excess amount of an aliphatic ester or an ester of benzoic acid in an aromatic hydrocarbon solvent in the presence of a sodium alkoxide condensing agent. Further, a method of recycling the solvent and a molar excess of the ester reactant after separation of the aromatic beta-diketone product. |
