[edit] Uses

It is commonly used as artificial flavoring such as pineapple flavoring in alcoholic beverages (i.e. martinis, daiquiris etc); solvent; in perfumery products and as a plasticizer for cellulose. In addition, Ethyl butyrate is often also added to orange juice, as most associate its odor with that of fresh orange juice.

[edit] Production

It can be synthesized by reacting ethanol and butyric acid. This is a condensation reaction, meaning water is produced in the reaction as a byproduct.
