Abstract

Acetic acid is prepared by oxidising acetaldehyde at elevated temperature in the liquid phase with oxygen or oxygen-containing gases in the presence of one or more heavy metal compounds as catalyst to initiate the reaction, the reaction mixture is admixed at the beginning of the oxygen feed with one or more organic peroxides which, under the reaction conditions, decompose with a half-life of up to 350 minutes into free radicals.
