Butyl acetate, also known as butyl ethanoate, is an organic compound commonly used as a solvent in the production of lacquers and other products. It is a colorless flammable liquid. Butyl acetate is found in many types of fruit, where along with other chemicals it imparts characteristic flavors and has a sweet smell of banana. It is used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods.

The other three isomers of n-butyl acetate are: isobutyl acetate, tert-butyl acetate, and sec-butyl acetate.



Butyl acetates are commonly manufactured by the Fischer esterification of a butanol isomer and acetic acid with the presence of catalytic sulfuric acid under reflux conditions.





Butyl acetate is a colorless, flammable liquid that is often used in organic chemistry laboratories as a solvent. Industrially, butyl acetate is used in the manufacture of lacquers, artificial leather, photographic films, plastics, and safety glass. It has a pleasant, fruity odor (rather like pears), and it is used in the flavoring/fragrance industry as an artificial flavoring. At high concentrations (200 ppm+) it is toxic.

Butyl acetate dissolves relatively easy in water. The volatility is reduced in water solution. It has a strong fruity smell and the taste is similar to banana.

This substance belongs to the group of esters, which normally is synthesized by a reaction between an organic acid and an alcohol, in this case acetic acid and butyl alcohol.

Butyl acetate occurs in a large amount of products. It is used as a solvent in many types of products. The largest use is in paint & lacquer. Other large uses are in adhesive and hardener. Butyl acetate is also used in production of medicals as a solvent/extraction agent. Minor uses occur also in anticorrosive agents, sealing agents, putty, cleaning agents and car care products. In paints, butyl acetate replaces older types of organic solvents that are associated with health and environmental problems.
