Manufacturer Good Price ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

short description:

ACETYL ACETONE, also known as diacetylmethane, pentamethylene dione, is a derivative of acetone, molecular formula CH3COCH2COCH3, colorless to light yellow transparent liquid. ACETYL ACETONE is usually a mixture of two tautomers, enol and ketone, which are in dynamic equilibrium. Enol Chemicalbook isomers form hydrogen bonds in the molecule. In the mixture, keto accounts for about 18%, and alkenes Alcohol form accounts for 82%. The petroleum ether solution of the mixture was cooled to -78°C, and the enol form was precipitated as a solid, so that the two were separated; when the enol form returned to room temperature,ACETYL ACETONE was automatically in the above equilibrium state.

Synonyms :acetyl;Acetyl2-propanone;acetyl-2-propanon;acetyl2-propanone;acetyl-aceton;CH3COCH2COCH3;pentan-2,4-dione;Pentanedione

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.
