Crotonic acid Usage And Synthesis
Chemical PropertiesWhite to light yellow crystalline flakes
Chemical Properties2-Butenoic acid is a crystalline compound with a pungent odor.
Preparation(E)-2-Butenoic acid may be formed by oxidation of crotonaldehyde, 2-butenal. If (Z)-butenoic acid is heated at 180°C, it is converted to (E)-2-butenoid acid.
Purification MethodsDistil the acid under reduced pressure and/or recrystallise it from pet ether (b 60-80o) or water, or by partial freezing of the melt. [Beilstein 2 IV 1498.]
