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 presente invención se refiere a la fabricación de benzoquinonas, en particular a la fabricación de una sal de potasio de una benzoquinona, tal como sal de dipotasio de 2,5-dihidroxi-1,4-benzoquinona. La sal de potasio de una benzoquinona se obtiene por oxidación de una hidroquinona usando hidróxido de potasio y peróxido de hidrógeno, lo que da por resultado un proceso eficiente con altos rendimientos.
