Chapter 2: Product Introduction

Acetylacetone, also known as diacetylmethane, pentamethylene dione, is a derivative of acetone, molecular formula CH3COCH2COCH3, clear colorless to light yellow liquid.

It is usually a mixture of two tautomers, enol and ketone, which are in dynamic equilibrium. The isomers in Enol form hydrogen bonds in the molecule. In the mixture, keto accounts for about 18%, and alkenes The 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, it was automatically found in the above equilibrium state.

Chapter 4: Product Usage

Acetylacetone is an intermediate in organic synthesis and forms amino-4,6-dimethylpyrimidine with guanidine, which is an important pharmaceutical raw material. It can be used as a solvent for cellulose acetate, additive for petrol and lubricants, desiccant for paints and varnishes, fungicide, and insecticide.

Acetylacetone can also be used as a catalyst for oil 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, over 50% is used in antidiarrheal drugs and feed additives for livestock.

In addition to the typical properties of alcohols and ketones, it also has a deep red color with ferric chloride and forms chelates with many metal salts. By condensation of acetic anhydride or acetyl chloride and acetone, or by reaction of acetone and ketene obtained.

It is used as a metal extractor to separate trivalent and tetravalent ions, desiccant for paints and inks, pesticides, pesticides, fungicides, solvents for high polymers, and reagents for the determination of thallium, iron, fluorine, and intermediates of organic synthesis, etc.

Transition metal chelators. Colorimetric determination of iron and fluorine and determination of thallium in the presence of carbon disulfide.

Fe (III) complexometric titration indicator; used for the modification of guanidine groups (eg Arg) and amino groups in proteins
