Acetylacetone, also known as diacetyl methane, pentanedione, is a derivative of acetone, the molecular formula CH3COCH2COCH3, colorless to light yellow transparent liquid. It is usually a mixture of enol and ketone tautomers. They are in dynamic equilibrium. The enol isomers form hydrogen bonds in the molecule. In the mixture, the ketone type accounts for 18% and the enol type accounts for 82%. When the petroleum ether solution of the mixture is cooled to - 78 C, the enol type precipitates in a solid form, separating the two, and when the enol type restores to room temperature, it is automatically in the above equilibrium state.

Acetylacetone is an intermediate of organic synthesis. It is an important pharmaceutical raw material to form amino-4,6-dimethylpyrimidine with guanidine. It can be used as solvent of cellulose acetate, additive of gasoline and lubricant, drying agent, bactericide, insecticide of paint and varnish, etc. Acetylacetone can also be used as catalysts for petroleum cracking, hydrogenation and carbonylation, as well as oxygen oxidation promoters. It can be used to remove metal oxides in porous solids and to deal with polypropylene catalyst. More than 50% of the European and American countries are used for livestock antidiarrheal and feed additives.
