4'-Methylacetophenone Chemical Properties,Uses,Production

Chemical Properties

clear colourless to pale yellowish liquid

Chemical Properties

4'-Methylacetophenone has been identified in Brazilian rosewood oil and in pepper. It occurs as colorless crystals with a floral, sweet odor that is milder than that of acetophenone. 4-Methylacetophenone is prepared from toluene and acetic anhydride or acetyl chloride by a Friedel–Crafts reaction. It is used for blossom notes in mimosaand hawthorn-type perfumes, especially soap perfumes.

Uses

4'-Methylacetophenone is a methylated acteophenone used in cosmetics and perfumery. The presence of 4'-Methylacetophenone has been shown to accelerate the photopolymerization of Methyl methacrylate.

Safety Profile

Moderately toxic by ingestion. A human skin irritant. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also KETONES.

Purification Methods

Impurities, including the o-and m-isomers, are removed by forming the semicarbazone (m 212-213.5o) which, after repeated crystallisation, is hydrolysed to the ketone. [Brown & Marino J Am Chem Soc 84 1236 1962.] It can also be purified by distillation under reduced pressure, followed by low temperature crystallisation from isopentane. [Beilstein 7 IV 701.]
