2-Butenoic acid is a crystalline compound with a pungent odor. | [Chemical Properties]
White to light yellow crystalline flakes | [Uses]
trans-Crotonic acid is used in the copolymerization of crotonic acid hydrogel systems by using gamma-rays. The crosslinked copolymeric crotonic acid hydrogels release fertilizers and drugs that help to prevent environmental pollution. | [Application]
Crotonic acid is an unsaturated fatty acid containing a double bond and a carboxyl group in its molecular structure, rendering it highly reactive. It serves various industrial applications, primarily in the preparation of resins, fungicides, surface coatings, plasticisers, and pharmaceuticals. | [Definition]
ChEBI: Crotonic acid is a but-2-enoic acid with a trans- double bond at C-2. It has been isolated from Daucus carota. It has a role as a plant metabolite. It is a conjugate acid of a crotonate. | [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. | [General Description]
Crotonic acid undergoes esterification with butan-2-ol by following second order reaction kinetics. | [Flammability and Explosibility]
Notclassified | [storage]
Store at RT | [Purification Methods]
Distil 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.] | [References]
