N-Butyl Acetate

n-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 or apple. It is used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods.

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

The excellent dissolving power of n-Butyl acetate, its good volatility, high dilutability (especially in a mixture with alcohols), and resistance to blushing of drying paint films make it one of the most important medium-volatility solvents. n-Butyl acetate may also be used in combination lacquers. It can be employed e.g. for the isocyanate component in catalysed lacquers. Because of its pleasant odor n-Butyl acetate may be used in the manufacture of essences, perfumes, stain removers and glazed paper.
