Introduction	reduced Blue 14 is dark blue powder, insoluble in water, acetone, toluene, ethanol, slightly soluble in chloroform, pyridine, soluble in O-chlorophenol. It was yellow-brown in concentrated sulfuric acid and blue after dilution. It is blue in the alkaline solution of sodium hydrosulfite and red-blue in the acidic solution.
Application	reduced Blue 14 is C.I. The monochloro derivative of reduced Blue 4, which is prepared by pigment treatment, can give red light and blue tone, with excellent light resistance, weather fastness and heat stability, and is mainly used in industrial coatings, coloring of rubber products and plastics.
purpose	reduced Blue GCDN is mainly used for cotton fiber dyeing and cotton printing, with good levelness and affinity. Also used for dyeing silk, vinylon, cotton, cotton and other fabrics. It can also be used to prepare ink pigments.
production method	with reduced Blue RSN as raw material, it is dissolved in sulfuric acid and manganese dioxide, and then through chlorine gas chlorination, after crystallization, acid washing, reduction, isolation, filtration, drying, grinding to obtain the finished product.
