OXIDATION OF ALKYLATED P-HYDROQUINONES IN AQUEOUS SOLUTIONS BY HYDROGEN PEROXIDE

The present invention relates to the oxidation of alkylated p-hydroquinones. It has been found the oxidation by aqueous hydrogen peroxide in the presence of a transition metal salt, which does not comprise any polydentate ligand bound to the metal ion, and an organic acid and water represents a part...

Zusammenfassung:	The present invention relates to the oxidation of alkylated p-hydroquinones. It has been found the oxidation by aqueous hydrogen peroxide in the presence of a transition metal salt, which does not comprise any polydentate ligand bound to the metal ion, and an organic acid and water represents a particularly efficient procedure for the manufacturing of alkylated p-benzoquinones. La présente invention concerne l'oxydation de p-hydroquinones alkylées. La présente invention concerne un procédé particulièrement efficace pour la production de p-benzoquinones alkylées comprenant une oxydation par peroxyde d'hydrogène aqueux en présence d'un sel de métal de transition, qui ne comprend pas de ligand polydentate lié à l'ion métallique, un acide organique et de l'eau.
