Acetophenone is a crystalline ketone that is used as a solvent for cellulose ethers and esters in the manufacture of alcohol-soluble resins.

These in turn are used in perfume. Acetophenone is used to create fragrances that resemble almond, cherry, honeysuckle, jasmine, and strawberry. It is used in chewing gum. It can be found naturally in apple, cheese, apricot, banana, beef and cauliflower.

This chemical may be obtained by the dry distillation of a mixture of the calcium salts of acetic and benzoic acids. Currently acetophenone mainly comes as a by-product of the phenol-acetone synthesis in the cumene oxidation process. At one time it was used as a hypnotic under the name of hypnone.

[edit] Cigarette additive

In a 1994 report released by five top cigarette companies, acetophenone was listed as one of the 599 additives to cigarettes.[1]
