Acetilacetona

La acetilacetona es un líquido claro, móvil, incoloro o ligeramente amarillento con un olor parecido al del cloroformo y una volatilidad moderada; tiene un punto de ebullición de 140 °C y un punto de fusión de −23 °C. Es un compuesto β-dicarbonílico y se clasifica como un intermedio químico orgánico. Su uso industrial principal deriva de su capacidad para formar quelatos metálicos estables, lo que la convierte en un precursor clave en la síntesis de acetoacetatos metálicos, ampliamente empleados como catalizadores, agentes de curado y aditivos. Sus áreas típicas de aplicación incluyen recubrimientos, polímeros, electrónica (por ejemplo, precursores para deposición química de vapor, CVD) y catalizadores especializados para procesos petroquímicos y de química fina.

1. Pentanedione, also known as acetyl acetone, is the intermediates of fungicides such as methyl mepanipyrim, mepanipyrim and herbicide pyrazosulfuron-methyl. 2. It can be used as the raw material of pharmaceutical and organic intermediates, as well as solvent.3. It can be used as a analysis reagent and the aluminum extraction agent from tungsten, molybdenum.4. 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.5. In addition to having the typical properties of alcohols and ketones, it can also exhibit dark red color together with iron dichloride, and form chelate with many kinds of salts. It is produced from the condensation reaction between acetic anhydride or acetyl chloride and acetone, or from the reaction between acetone and diketene. It can be used as metal extraction agent for separation of three or tetravalent ions; it can also be used as paints and inks desiccant, pesticides, fungicides, and the solvent of polymer; moreover, it can also used as reagents for determination of thallium, iron, fluorine and be used as the intermediates for organic synthesis.6. It can be as a transition metal chelator. It can be used for measuring the content of iron and fluorine with colorimetric determination, or used for measuring thallium in the presence of carbon disulfide.7. It is the indicator for Fe (III) complex titration; it can be used for modifying the guanidine groups and amino-groups inside a protein.
