Zusammenfassung:The present invention relates to the manufacture of benzoquinones, in particular to the manufacture of a potassium salt of a benzoquinone, such as 2,5-dihydroxy-l,4-benzoquinone di-potassium salt. The potassium salt of a benzoquinone is obtained by oxidation of a hydroquinone using potassium hydroxide and hydrogen peroxide, which results in an efficient process with high yields. La présente invention concerne la fabrication de benzoquinones, en particulier la fabrication d'un sel de potassium d'une benzoquinone, tel que le sel de di-potassium de 2,5-dihydroxy-l,4-benzoquinone. Le sel de potassium d'une benzoquinone est obtenu par oxydation d'une hydroquinone à l'aide d'hydroxyde de potassium et de peroxyde d'hydrogène, ce qui permet d'obtenir un procédé efficace avec des rendements élevés.
