STABLE CHEMICAL COMPOSITIONS CONTAINING CHROMOGENIC MATERIALS OR MIXTURES OF CHROMOGENIC MATERIALS AND PEROXIDES, AND STABILIZING CHEMICAL COMPOSITIONS AND METHODS FOR OBTAINING THE STABLE CHEMICAL COMPOSITIONS

摘要

ABSTRACTChromogenic materials which react to give a color reaction when inthe presence of a peroxide ROOR' decomposing to give a radicaloxygen are unstable when dissolved to give working solutions for usein chromogenic reactions. Compositions containing in addition tothe chromogenic material also a peroxide needed in the said reactionare also unstable, leading to premature appearance of color. Stablechemical compositions containing chromogenic materials and stablecompositions containing mixtures of chromogenic materials andperoxides are described, which can be used in chromogenic reactionsafter having been stored for long periods of time. Also describedare stabilizing chemical compositions and methods for obtaining thesaid stable compositions.
