Product Application of Acetylacetone CAS#123-54-6

Pentanedione, also known as Acetylacetone, is the intermediates of fungicides such as methyl mepanipyrim, mepanipyrim and herbicide pyrazosulfuron-methyl. It can be used as a analysis reagent and the aluminum extraction agent from tungsten, molybdenum. Acetylacetone is a kind of intermediate of organic synthesis which produces amino-4,6-dimethyl-pyrimidine with guanidine; it is an important pharmaceutical raw materials. It can be used as the solvent for cellulose acetate, as gasoline and lubricant additives, as desiccants of paints and varnishes, and as fungicides as well as insecticides. Acetylacetone can also serve as a catalyst for cracking petroleum, hydrogenation and hydroformylation reactions as well as being the oxidation promoting agent of oxygen. It can be used to remove the metal oxides in porous solid and used for processing polypropylene. In the United States and Europe, it is used for the antidiarrheal medicine and livestock feed additives in more than 50% of cases.
