Black powder. Water-soluble General, its aqueous solution is blue; Slightly soluble in ethylene glycol ether, very slightly soluble in ethanol, insoluble in other organic solvents. The addition of concentrated hydrochloric acid to the aqueous solution resulted in a blue precipitate, and the addition of concentrated alkali resulted in a reddish purple precipitate. It is blue to gray-black in concentrated sulfuric acid, and produces red violet precipitate after dilution; It is dark brown in concentrated nitric acid; It is insoluble in concentrated alkali solution; It is blue-purple in concentrated ammonia solution. There was slight change in color of copper and iron ions during staining.

amino c acid, methyl naphthylamine, 1,7 cliffic acid and j acid are the basic raw materials. Amino C acid is diazotized (primary diazotization), coupled with methylnaphthylamine (primary coupling), the primary coupling is re-diazotized (secondary diazotization), and then with 1,7-Cliff acid is coupled (secondary coupling), the secondary coupling is re-diazotized (tertiary diazotization), and then coupled with J acid (tertiary coupling). It is then salted out, filtered and dried. Kg/ton amino C acid (100%) 230 soda ash (industrial) 450 carmine (100%) 110 caustic soda (100%) 2101, 7-cliffic acid (100%) 160 sodium acetate 630J acid (100%) 160 urea 15 sodium nitrite (industrial) 177 industrial soap 13 sulfuric acid (100%) 300 refined salt 2200 hydrochloric acid (31%) 600
with 2-naphthylamine -4,8-disulfonic acid (amino C acid), 1-naphthylamine, 8-amino -2-naphthylsulfonic acid (1,7-Cleve's Acid, 1,7-Cliff acid), and J acid are used as raw materials. First, 3-amino -1,5-naphthyldisulfonic acid is diazotized, coupled with 1-naphthylamine for the first time, and then the coupled product is diazotized, and 1, 7-Cliff acid is coupled for the second time, and then the coupling product is diazotized, and the product is coupled with J acid for the third time to obtain the product. The finished product is salted out, filtered, dried and crushed.. 11.45kg of amino C acid (100%), 2.61kg of sodium nitrite (100%), 12.5kg of sulfuric acid (d154 1.383) were diazotized to obtain (I), and (II) was obtained by coupling with 5.5kg 1-naphthylamine for 5h. Then (II) is diazotized and coupled with 9.36kg 1, 7-cliffic acid for 7h to obtain (III). Then (III) diazotization, coupling with 8.6kg J acid (100%) for 2 hours, heating to 70 ℃, salting out with 80kg of salt (industrial products), filtering and drying to obtain dye.
