Abstract
A process for the separation of a mixture of isomers of 1,4-dihydroxy-1,2,3,4-tetrahydrophenazine-5,10-dioxides in the individual isomers a and b, characterized in that it comprises dissolving the mixture of isomers in dimethyl sulphoxide, separating the insoluble complex of dimethyl sulfoxide-isomer a, and recovering the soluble isomer b from the dimethyl sulfoxide solution.
