Process for the oxidation of alcohols to aldehydes and ketones in the presence of nitroxyl compounds as catalysts

摘要

An alcohol is oxidized to an aldehyde or a ketone in the presence of a nitroxyl compound as catalyst, wherein the alcohol to be oxidized is contained in an organic liquid phase, and is reacted in the presence of a nitroxyl compound with an aqueous phase comprising an oxidant. The reaction is carried out continuously at a contact time of the phases of from 0.1 s to a maximum of 15 minutes, with intensive mixing of the phases. The process produces high yields with low quantities of other oxidation byproducts.
