Raw material formule for preparing keto isophorone and its method

The present invention provides a preparation method of keto-isophorone and its formula of raw materials. The formula of raw materials: solvent; Organic base; Catalyst; beta - isophorone; Catalyst is metal-organic ligand combined by copper ions and Schiff base that takes salicylaldehyde or its derivatives as the main structure with 10% of the metal-organic ligand; The Preparation : According to theabove formula, first add solvent, organic base and catalyst into reactor, and then add beta - isophorone; put in adequate oxygen, and then pressurized to 0 to 1MPa, control the whole reaction temperature at 20 to 00deg, the reaction time for one to eight hours, at last obtain keto-isophorone. The features are the speed reaction, high-yield, production time and space efficiency is greatly enhanced.
