Abstract

Crotonic acid is prepared by catalytic oxidation of crotonaldehyde with oxygen in a liquid medium at 5-10 DEG C. The solvent is preferably glacial acetic acid, and the catalyst preferably comprises a mixture of manganese acetate and potassium permanganate. The oxidation may be made continuous by alternately using dual oxidation vessels.
