Esters are widespread throughout
nature, but are also a vital use in industry. The synthesis of low molecular weight esters, by the
reaction of a carbonyl with an alcohol, is essential to the fragrance and flavoring industry. nButyl
acetate is a widely known ester used as a solvent in the production of lacquers, but more
commonly as a synthetic apple flavoring used in foods such as ice cream, candy, jams, and baked
goods.
