Stability of Indanetrione Hydrate Solutions

Abstract

THE maximum yield of the coloured complex formed by the reaction of indanetrione hydrate1 and a compound containing an amino-group2 may be obtained when a reducing substance is present in the reaction mixture. Stannous chloride3, hydrindantin4 or potassium cyanide5 may be used as a suitable reducing substance in the reaction mixture, provided the reaction occurs at a controlled pH3,6.
