Manufacturing Methods : (a) will be blue anthrone chlorinated, method is (1) and fuming nitric acid and hydrochloric acid action; (2) and Sulfuryl chloride azeotropic; (3) and Benzoyl chloride , copper powder and Nitrobenzene action; (b) Phthalic anhydride and Chlorobenzene condensation, its product Chloro – benzoyl benzoic acid nitration, nitrocellulose reduction, cyclization, will product 2-Amino-3-chloroanthracene-9,10-dione bromination and will last a 2-Amino-1-bromo-3-chloroanthracene-9,10-diorne in copper catalyst and acid binding agent under the existence of condensation; (C) will be 2-Amino-1,3-dichloroanthraquinone in Acid binding agent and the presence of Halogenated cuprous heating; (d) in an inert solvent with Sulfuryl chloride processing C.I. Vat Blue 11 (C.I. 69815), and the formation of complex decomposition. Note: use (b) method for product, improve the reducibility and levelness, it easier to generate leuco sulfate.

Properties and Applications:  brilliant blue. Aquamarine blue powder. Slightly soluble in hot Chloroform, 2 – Chlorophenol and hot Pyridine ; Insoluble in water, Acetone, Etanol and Toluene. Alkaline reduction leuco for green light yellow, acid reduction leuco for red light blue. In concentrated sulfuric acid for brown, dilution for blue. More sensitive to hard water. Mainly used in cotton fiber dyeing, easy excessive reduction and excessive oxidation, the dyeing speed, generally not used for printing. Used for silk dyeing, levelness and affinity are good. Used to stick/cotton blended fabric cold dyeing, uniform color. Also can be used for polyester/cotton two bath dyeing. Can also be processed into organic pigment.
