Abstract:
The present invention relates to a process for preparing 4-pentenoic acid, at least comprising the oxidation of a mixture (G) comprising 4-pentenal, 3-methyl-2-butanone and cyclopentene oxide, and to the use of a mixture (G) comprising 4-pentenal, 3-methyl-2-butanone and cyclopentene oxide for preparing 4-pentenoic acid. In the context of the present invention, the mixture (G) is preferably obtained as a by-product of the oxidation of cyclopentene to cyclopentanone by means of dinitrogen monoxide.
