Acetone derivatives

Acetylacetone is a derivative of acetone; chemical formula: CH3COCH2COCH3; It is colorless to pale yellow transparent liquid. It is usually the mixture is enol form and keto form which are the tautomers of each other; these two forms are in dynamic equilibrium; enol isomer forms hydrogen bonds inside the molecule; in the mixture, the keto form accounts for about 18% and enol type accounted for 82%. Cool the petroleum ether of their mixture to-78 °C so the enol will be precipitated as a solid and the two forms will be separated with each other. Upon the enol form being returned back to room temperature, the above equilibrium will be restored.
Reaction formula
Acetylacetonate have a pleasant odor. It is flammable, and has a relative molecular mass of 100.13. Its relative density is 0.9721 (25 °C). Its melting point is-23.5 °C and boiling point is 140.5 °C or 139 °C (99.458 × 103Pa). Its flash point is 41 °C. The refractive index is 1.4494. It has a vapor pressure of 0.800 × 103Pa (20 °C). (At 20 °C 16.9,80 °C at 34) and is soluble in water, ethanol, benzene, chloroform, ether, acetone, ethyl acetate and acetic acid. It is susceptible to hydrolysis to generate acetic acid and acetone. The molecular structure of the acetylacetone is a saturated diketone structure in which two hydroxyl groups are connected by a methylene group; this form is usually referred to as β-diketone. Acetylacetone is also one of the simplest saturated β-diketones and is a derivative of acetone. It has an active chemical property and can react with ferric chloride aqueous solution to exhibit a dark red color. This product can almost react with the hydroxides, carbonates or acetates of all metals to form a complex with a general formula being (C5H7O2) • M, wherein M corresponds to the metal element and n is the metal compounds. Most of such compounds are stable, and many of them are soluble in many organic solvents. This product can have reaction with chlorine in the presence of light of with only two ends of methyl hydrogen being replaced by chlorine. When this product is reacted with sodium, it can release hydrogen and generates sodium acetylacetonate. Acetylacetonate have a narcotic effect and can stimulate the skin and mucous membranes; at high concentrations (100 × 10-6 or more), it is easy to produce some symptoms of poisoning such as nausea, headache, and dizziness. Rat oral LD50: 970mg/kg.

Intermediates of organic synthesis

Acetylacetone is an important intermediate for organic synthesis which is widely used in pharmaceutical, perfume, pesticides and other industries.
Acetylacetone is an important raw material in the pharmaceutical industry, such as for the synthesis of 4,6-dimethyl-pyrimidine derivatives. It can also be used as the solvents for cellulose acetate, the drying agent for paints and varnishes, etc., and are also important analytical reagents.
Due to the presence of enol, acetylacetone can form chelate with a variety of metals such as cobalt (II), Co (III), beryllium, aluminum, and chromium, iron (II), copper, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium and thorium; it can also be used as fuel additives and lubricant additives.
Taking advantage of its chelation reaction with many kinds of metals, it can be used as a kind of metal cleaning agent for micropore; It can also used as a catalyst, a resin cross-linking agent, the resin curing accelerator; resins, rubber additives; for the hydroxylation reaction, hydrogenation reaction, isomerized reaction, and the synthesis of low molecular weight unsaturated ketone as well as polymerization and copolymerization of low-carbon olefins; it can also be used as an organic solvent for dissolving cellulose acetate, ink, and paint; it can also used as paint drying agent; it can also be used as the raw materials for preparation of insecticide, fungicide materials, and animals laxatives as well as feed additives; it can also be used as infrared reflective glass, a transparent conductive film (indium salt), a superconducting thin film (indium salt) forming agent; acetylacetone metal complexes has special colors (green copper salts, iron red, purple chromium salt) and is insoluble in water; it can also be used as pharmaceutical raw materials and raw materials for organic synthesis.
