Acetophenone is also known as acetyl benzene with the boiling point (℃) being 202.3, relative density (water = 1) being 1.03 (20 ℃) and the relative vapor density (air = 1) being 4.14. It is the simplest aromatic ketones with its aromatic core (benzene ring) being directly connected with a carbonyl group. It is presented in some kinds of essential oils of some plants in its free-state form. It is pure colorless crystals. Most commercially available product appears as pale yellow oily liquid with hawthorn like aroma. It is only slightly soluble in water and is easily soluble in many organic solvents and can be evaporated together with the steam. The molecular structure of acetophenone: methyl C atom is bonded through sp3 hybrid orbital while the benzene ring and the carbonyl C atom are bonded through sp2 hybrid orbital. Addition reaction and [alpha] active hydrogen reaction can occur for the carbonyl group of acetophenone. It can also have electrophilic substitution reaction in its benzene ring with the major product generated being in the meta-position. Acetophenone can be produced from the reaction between benzene with acetyl chloride, acetic anhydride or acetate under the catalysis of aluminum trichloride. Furthermore, when ethylbenzene is catalyzed and oxidized into styrene, it can also generate acetophenone as by-product. Acetophenone is mainly used as the raw materials for pharmaceuticals and other kind of organic synthesis. It can also used for the preparation of spices, soap and cigarettes as well as being used as the solvents of cellulose ether, cellulose ester and resin and plasticizer. It has hypnotic effect. Currently, acetophenone is mostly obtained via the by-product of reaction between phenol and acetone via cumene oxidation. It may be obtained through the acetylation on benzene through acetyl chloride.
