Classification Code of Benzyl acetate (CAS NO.140-11-4): Human Data; Mutation data; Skin / Eye Irritant; Tumor data
Benzyl acetate (CAS NO.140-11-4) is used widely in perfumery and cosmetics for its aroma and in flavorings to impart apple and pear flavors. Benzyl acetate is commonly used as bait to attract and collect these bees for study. It is also used as a solvent in plastics and resin, cellulose acetate, nitrate, lacquers, oils, polishes and inks.
Benzyl acetate (CAS NO.140-11-4) is prepared by esterification of benzyl alcohol, by heating with either an excess of acetic anhydride or acetic acid with mineral acids.
C6H5CH2OH + CH3CO2H → C6H5CH2OCOCH3
The product is purified by treatment with boric acid and distilled to a purityIn excess of 98%.
