Butyl acetate CAS# 123-86-4
Butyl acetate is a clear, flammable ester of acetic acid that occurs in n-, sec-, and tert- forms (INCHEM, 2005). Butyl acetate isomers have a fruity, banana-like odor (Furia, 1980). Isomers of butyl acetate are found in apples (Nicholas, 1973) and other fruits (Bisesi, 1994), as a well as in a number of food products, such as cheese, coffee, beer, roasted nuts, vinegar (Maarse and Visscher, 1989). Butyl acetate is manufactured via esterification of the respective alcohol with acetic acid or acetic anhydride (Bisesi, 1994). N-butyl acetate is used as a solvent for nitrocellulose-based lacquers, inks, and adhesives. Other uses include manufacture of artificial leathers, photographic film, safety glass, and plastics (Budavari, 1996). Isomers of butyl acetate are also used as flavoring agents, in manicure products, and as larvicides (Bisesi, 1994). The tert-isomer has been used as a gasoline additive (Budavari, 1996). It may be used as a synthetic fruit flavoring in candy, ice cream, cheeses, and baked goods (Dikshith, 2013).

Product Application of Butyl acetate CAS# 123-86-4
Butyl acetate is one of the more important derivatives of n-butyl alcohol produced commercially, is employed as a solvent in rapid drying paints and coatings. In some instances, butyl acetate, C6H12O2, has replaced ethoxyethyl acetate due to the latter’s reported toxicity and teratogenicity.
