Acetophenone, also called acetophenone, boiling point (℃) : 202.3, the relative density (water = 1) : 1.03 (20 ℃), the relative vapor density (air = 1) : 4.14, is the most simple aromatic ketone, the aromatic nucleus (benzene) is directly connected to the carbonyl group.
It is found in the essential oil of some plants.
Purity is a colorless crystal.
The sale of goods in the city is a light yellow oily liquid.
There is the aroma of the hawthorn.
It is soluble in water and soluble in many organic solvents. It can evaporate with the steam.
The molecular structure of acetophenone: the methyl C atom is formed by the sp3 hybridization, and the benzene ring and the carbonyl C atom are bonded by the sp2 hybridized orbital.
The reaction of the addition of a carbonyl group to a carbonyl group, the reaction of alpha reactive hydrogen, and the electrophilic substitution reaction of the benzene ring, the main formation of the meta-product.
Acetophenone can be catalyzed by trichloride, which is catalyzed by benzene and acetyl chloride, acetic acid anhydride or acetic acid.
In addition, acetophenone is a by-product of phenyl oxide catalyzed by ethylene oxide.
Acetophenone is used primarily for pharmaceutical and other organic materials, as well as for the preparation of spices.
Used for soap and cigarettes, it can also be used as solvent such as cellulose ether, cellulose ester and resin and plastic plasticizer, which is hypnotic.
It is now made up mostly of phenylphenol and acetone by-products, which can also be made from acetyl chloride.
