Ethyl crotonate Use and Manufacturing

Methods of Manufacturing

It is formed by esterification of crotonic acid and ethanol in the presence of concentrated sulfuric acid.

Uses

Used as organic synthesis intermediate, solvent, paint softener.

Ethyl crotonate is used as a solvent for cellulose esters as well as a plasticizer for acrylic resins.

Ethyl Crotonate is a synthetic flavoring agent that is a moderately stable, colorless to light yellow liquid of sharp winey note. it should be stored in glass, tin, or resin-lined containers. it is used in fruit flavors for application in baked goods, beverages, and candy at 2–7 ppm.

Solvent and softening agent, lacquers, organic synthesis.The commercial Ethyl crotonate, used in flavor compositions, is a liquid. It has a powerful and diffusive, sourcaramellic-fruity odor, reminiscent of unripe berries. This ester is used in imitation Strawberry, occasionally also in Pineapple or other imitation fruit flavors. The concentration used is generally very low, classified as "traces" only.
