LOW-WASTE TECHNOLOGY FOR THE PRODUCTION OF CATIONIC DIAMINOANTHRAQUINONE DYES
-
Shteinberg, Ya. B.,Slavutskaya, L. M.
p. 2569 - 2570

Action of Sodium Dithionite on Some Cationic Dyes
Sodium dithionite (SDT) has been developed as a useful reagent to dequaternize a variety of cationic dyes.Triarylmethane dyes are converted into leuco bases; however, hemicyanines smoothly undergo dehydrochlorination.Phenothiazine and phenoxazine dyes on reduction with SDT give unstable leuco bases, which can be isolated as their N-benzoyl derivatives.The IR, PMR and mass spectral studies of the leuco bases or the dequaternized products have been found to be useful for structure elucidation of the cationic dyes.
