Abstract

1. Process for the preparation of para-benzoquinones by the oxidation of phenol, or of phenols which are monosubstituted or polysubstituted in the ortho- and/or metaposition, with molecular oxygen or a gas containing molecular oxygen, the reaction being carried out in an organic solvent, in the presence of cuprous or cupric ions, characterized in that the reaction is carried out in a ketone, as the solvent, and also in the presence of carboxylate or phenate ions.
