Pentanedione 2, 4-

Acetylacetone is a colorless liquid with an unpleasant odor. Though the compound exists in two tautomeric forms, they’re usually treated as a single compound in most applications.

Acetylacetone other common names include, Diacetylmethane, Acetyl 2-propanone, 2,4-pentanedione, Penta-2,4-dione and often shortened to AcAc. The compound is one of the simplest liquid beta-diketones commonly produced by the rearrangement of Isopropenyl acetate. Other methods of producing the acetylacetone include the addition and decarbonation of ketene and ethyl acetoacetate.

Acetylacetone boiling point is 1400C and -230C melting point. It is miscible with most organic solvents including alcohol, acetic acid, ether, acetone and chloroform. Acetylacetone is soluble in water producing a flammable and corrosive solution.

Acetylacetone is commonly used as intermediates in the production of fungicides, such as herbicide pyrazosulfuron, methyl mepanipyrim and mepanipyrim. It is also used as a solvent and raw material of organic and pharmaceutical intermediates, a catalysis for cracking petroleum, hydroformylation and hydrogenation, a transition metal chelator, a metal extraction agent, reagents for determination of fluorine, thallium or iron and also as the indicator for Iron (III) complex titration.
