Application

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.

General description

Crotonic acid undergoes esterification with butan-2-ol by following second order reaction kinetics.

Preparation Note

Crotonic acid dissolves in water at a concentartion of 100 mg/ml to yield a clear, colorless solution.
