Versuchsvorschrift

A process according to claim 1, wherein manganese(II) sulfate is oxidised anodically in 80 to 90% sulfuric acid, in the presence of 4,4'-bibenzanthrone, to give manganese(III) sulfate, which acts in situ as an oxidising agent and converts 4,4'-bibenzanthrone into dioxoviolanthrone.
