Instruction:
It can be used as raw materials and organic intermediates of pharmaceutical, and also as solvent. Acetylacetone is an intermediate of organic synthesis. It forms amino-4,6-dimethylpyrimidine with guanidine. It is an important pharmaceutical raw material. It can be used as solvent of cellulose acetate, additive of gasoline and lubricant, desiccant of paint and varnish, bactericidal chemical book agent, insecticide, etc. Acetylacetone can also be used as catalyst for petroleum cracking, hydrogenation and carbonylation, as well as oxygen oxidation promoter. It can be used to remove metal oxides from porous solids and to treat polypropylene catalysts.
In addition to the typical properties of alcohols and ketones, it also shows deep red color with ferric dichloride and forms chelates with many metal salts. It is prepared by condensation of acetic anhydride or acetyl chloride with acetone, or by reaction of acetone with ketene. It is used as metal extractant to separate trivalent and tetravalent ions, paint and ink desiccant, pesticide, pesticide, fungicide, polymer solvent, reagent for the determination of thallium, iron, fluorine and organic synthesis intermediates.
Acetylacetone is an important intermediate in organic synthesis, which is widely used in pharmaceutical, perfume, pesticide and other industries.
Acetylacetone 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.
Because of the enol form, acetylacetone can form chelates with metal ions such as cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminum, chromium, iron (Ⅱ), copper, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium and thorium, which can be used as fuel oil additive and lubricating oil additive.
It can be used as cleaning agent of metal in micropore, catalyst, resin crosslinking agent, resin curing accelerator, resin and rubber additive, hydroxylation reaction, hydrogenation reaction, isomerization reaction, synthesis of low molecular unsaturated ketone, polymerization and copolymerization of low carbon olefin, organic solvent, cellulose acetate, ink and pigment; Paint desiccant; raw materials for preparation of insecticidal and bactericide, animal antidiarrheal and feed additive; infrared reflective glass, transparent conductive film (indium salt), superconducting film (indium salt) forming agent; acetylacetone metal complex with special color (copper salt green, iron salt red, chromium salt purple) and insoluble in water; used as pharmaceutical raw materials; organic synthetic raw materials
