Acetylacetone,also known as 2, 4-pentadione, is an organic compound, chemical formula C5H8O2, colorless to slightly yellow transparent liquid, slightly soluble in water, and ethanol, ether, chloroform, acetone, ice acetic acid and other organic solvents miscible, mainly used as solvent, extraction agent, can also be used in the preparation of gasoline additives, lubricants, mold insecticides, pesticides, dyes, etc.
Properties:Acetone is colorless or slightly yellow flammable liquid. The boiling point is 135-137 ° C, the flash point is 34 ° C, and the melting point is -23 ° C. The relative density is 0.976, the discount rate is N20d1.4512. The acetone is soluble in 8g of water, and it is mixed with ethanol, benzene, chloroform, ether, acetone, and methampitic acid, and is decomposed into acetone and acetic acid in the alkali solution. When it comes to high fever, light fire and strong oxidant, it is easy to cause burning. Unstable in water, easily hydrolyzed into acetic acid and acetone.
Intermediate for organic synthesis:
Acetylacetone is an important intermediate in organic synthesis, widely used in pharmaceutical, fragrance, pesticide and other industries.
Acetone is an important raw material in pharmaceutical industry, such as the synthesis of 4,6 – dimethylpyrimidine derivatives. It is also used as a solvent for cellulose acetate, a desiccant for paints and varnishes, and an important analytical reagent.
Due to the existence of enol form, acetylacetone can form chelates with cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminum, chromium, iron (Ⅱ), copper, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium and thorium and other metal ions, which can be used as additives in fuel oil and lubricating oil.
The Chemicalbook can be used as a cleaning agent for metals in micropores by its chelation with metals. Used as catalyst, resin crosslinking agent, resin curing accelerator; Resin, rubber additives; Used for hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis and low carbon olefin polymerization and copolymerization; Used as organic solvent, used for cellulose acetate, ink, pigment; Paint drying agent; Raw materials for the preparation of insecticides and fungicides, animal antidiarrheal drugs and feed additives; Infrared reflection glass, transparent conductive film (indium salt), superconducting film (indium salt) forming agent; Acetylacetone metal complex has a special color (copper salt green, iron salt red, chromium salt purple) and insoluble in water; Used as raw materials for medicine; Organic synthetic materials.
Applications Of ACETYL ACETONE：
1. Pentanedione, also known as acetylacetone, is the intermediate of the fungicides pyraclostrobin, azoxystrobin and the herbicide rimsulfuron.
2. It can be used as raw materials and organic intermediates for pharmaceuticals, and can also be used as solvents.
3. Used as analytical reagent and extraction agent of aluminum in tungsten and molybdenum.
4. Acetylacetone is an intermediate in organic synthesis, and it forms amino-4,6-dimethylpyrimidine with guanidine, which is an important pharmaceutical raw material. It can be used as a solvent for cellulose acetate, an additive for gasoline and lubricants, a desiccant for paint and varnish, a fungicide, and an insecticide. Acetylacetone can also be used as a catalyst for petroleum cracking, hydrogenation and carbonylation reactions, and an oxidation accelerator for oxygen. It can be used to remove metal oxides in porous solids and to treat polypropylene catalysts. In European and American countries, more than 50% are used in livestock antidiarrheal drugs and feed additives.
5. In addition to the typical properties of alcohols and ketones, it also exhibits dark red color with ferric chloride and forms chelates with many metal salts. By acetic anhydride or acetyl chloride and acetone condensation, or by the reaction of acetone and ketene obtained. Chemicalbook is used as metal extractant to separate trivalent and tetravalent ions, paint and ink driers, pesticides, pesticides, fungicides, solvents for high polymers, reagents for the determination of thallium, iron, fluorine, and organic synthesis intermediates.
6. Transition metal chelators. Colorimetric determination of iron and fluorine, and determination of thallium in the presence of carbon disulfide.
7. Fe(III) complexometric titration indicator; used for modification of guanidine groups (such as Arg) and amino groups in proteins.
8. Used as transition metal chelating agent; used for colorimetric determination of iron and fluorine, and determination of thallium in the presence of carbon disulfide.
9. An indicator for iron (III) complexometric titration. Used to modify guanidine groups in proteins and amino groups in proteins.
