ESTERS

Butyl acetate, also known as butyl ethanoate, is an ester that is a colorless, flammable liquid at room temperature. It 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.
Application & Usage:

The primary use of all three isomers of butyl acetate is as a solvent in the production of lacquers and paints; photographic film; resins; and coatings for furniture, fixtures, containers, and automobiles. Since the 1990s, these compounds have been substituted for other solvents that are considered hazardous environmental pollutants.

Other uses of the isomers are as follows:

• n-butyl acetate: as an odor enhancer in perfumes; in the synthesis of synthetics flavors, pharmaceuticals, and other organic compounds;
• sec-butyl acetate: as a thinner for nail enamels and a solvent for leather finishes;
• tert-butyl acetate: as a gasoline additive.
