Ethyl crotonate Usage And Synthesis
Chemical propertiesIt appears as colorless to pale yellow liquid with the boiling point of 136 ° C and flash point of 22 ° C. It exhibits strong acid coke and fruit aroma with the incense of rum and ether.
The natural products exist in apples, papaya, strawberries, rums, wines and cocoa.
  • It as allowable food spices. Mainly used for the preparation of fruit wine flavor.
  • Used as the intermediate of organic synthesis, solvents, paint softener.
ProductionIt is obtained from the esterification of crotonic acid and ethanol in the presence of concentrated sulfuric acid.
Chemical Propertiescolourless liquid
Chemical PropertiesEthyl crotonate has a powerful, sour, caramellic-fruity odor.
OccurrenceReported found in Fragaria vesca. Also reported found in guava fruit, guava peel, pineapple, white wine, yellow passion fruit, fresh mango, naranjilla fruit, mussel, loganberry, apple, papaya, concord grape, strawberry, rum, cocoa, plum, kiwifruit and other natural sources.
UsesEthyl 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.
UsesSolvent and softening agent, lacquers, organic synthesis.
PreparationBy esterification of crotonic acid with ethyl alcohol in the presence of concentrated H2SO4.
Taste threshold valuesTaste characteristics at 10 ppm: rum, cognac and pungent with caramellic and fruity nuances.
HazardFlammable, dangerous fire risk. Strong irritant.
Safety ProfileModerately toxic by ingestion and probably by inhalation. A skin , mucous membrane, and severe eye irritant. Very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use foam, CO2, or dry chemical. See also ESTERS. When heated to decomposition it emits acrid smoke and fumes.
Purification MethodsWash it with aqueous 5% Na2CO3, then with saturated aqueous CaCl2, dry it with CaCl2 and distil it. [Beilstein 2 IV 1500.]
