chemical properties

acetone is a representative compound of aliphatic ketones and has a typical reaction of ketones. For example, a colorless crystalline adduct is formed with sodium bisulfite. Reaction with hydrogen cyanide produces acetone cyanohydrin. Under the action of reducing agent, isopropanol and pinacolone are generated. Acetone is relatively stable to oxidants. It is not oxidized by nitric acid at room temperature. When the strong oxidant of acidic potassium permanganate is used as the oxidant, acetic acid, carbon dioxide and water are generated. Bimolecular condensation occurs in the presence of a base to give diacetone alcohol.

2 mol of acetone in the presence of various acidic catalysts (hydrochloric acid, zinc chloride or sulfuric acid) to produce isopropylideneacetone, which is added to 1 mol of acetone to produce phorone (diisopropylideneacetone). 3 mol of acetone under the action of concentrated sulfuric acid, 3 mol of water generation between three toluene. Condensation in the presence of lime, sodium alkoxide or sodium amide yields isophorone (3,5,-trimethyl-2-cyclohexene-1-one).-.

in the presence of acid or alkali, and aldehyde or ketone condensation reaction, the generation of ketone alcohol, unsaturated ketone and resin-like substances. and phenol under acidic conditions, condensation of bisphenol A. The α- hydrogen atom of acetone is easily replaced by a halogen to produce an α- haloacetone. It reacts with an alkaline solution of sodium hypohalite or halogen to form a haloform. The addition reaction of acetone and Grignard reagent occurs, and the addition product is hydrolyzed to obtain tertiary alcohol. The condensation reaction of acetone with ammonia and its derivatives such as hydroxylamine, hydrazine, phenylhydrazine and the like can also take place. In addition, acetone is cracked at 500~1000 °C to produce ketene. Isobutylene and acetaldehyde are generated by silicon-aluminum catalyst at 170~260 ℃, and isobutylene and acetic acid are generated at 300~350 ℃. It cannot be oxidized by weak oxidants such as silver ammonia solution and newly prepared copper hydroxide, but it can catalyze hydrogenation to form alcohol.

Preparation method

dry distillation method

In the cumene method has not been invented before, early acetone by calcium acetate distillation.

fermentation method

Acetone can be obtained fermentation with butanol yeast. This law was developed by Haim Weizmann during the First World War, but was soon abandoned due to its extremely low yield.

cumene oxidation synthesis method

With petroleum industry products cumene in sulfuric acid catalysis with oxygen reaction to produce acetone and its by-product phenol, the method produces little waste and low price, so the current main use of this method for production.

oxidation of isopropanol method

Using potassium dichromate or other oxidizing agent oxidation of isopropyl alcohol, acetone.

hydrolysis of propyne

Acetone can be prepared by hydrolysis of propyne, but it needs mercuric sulfate catalysis. The process produces an unstable enol, which is then isomerized into acetone.
