METHOD FOR PRODUCING 2,3,5-TRIMETHYLBENZOQUINONE BY OXIDATION OF 2,3,6-TRIMETHYLPHENOL

摘要

The present invention is a mixture containing 2,3,5-trimethylbenzoquinone, which mixture can be prepared or prepared by a process for preparing a mixture containing 2,3,5-trimethylbenzoquinone, comprising the following step: oxidation of 2,3,6 -Trimethylphenol with oxygen or an oxygen-containing gas in a two- or multi-phase reaction medium in the presence of a catalyst or catalyst system at least comprising a copper (II) halide to a mixture containing 2,3,5-trimethylbenzoquinone, characterized in that the reaction medium is water and contains at least one secondary aliphatic acyclic alcohol having 6 or more, preferably 7 or more, carbon atoms.
