Flavanthrone Use and Manufacturing

Methods of Manufacturing

Using 1-chloro-2-acetamidoanthraquinone as raw material, in DMF medium, copper powder is used as a catalyst to complete the dechlorination and condensation reaction. After copper is removed, the product is hydrolyzed and closed in the presence of concentrated sulfuric acid.

Uses

Reduced Yellow G is mainly used for dyeing and printing cotton, Uygur and Uygur/cotton, polyester/cotton. It has good affinity for cotton fiber and good level dyeing property. Due to its difficulty in oxidation, it is oxidized with hydrogen peroxide or sodium perborate to obtain bright colors. It is also used to make organic pigments.
