Table of physical properties

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.

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.
