Use	mainly used for dyeing silk, wool, nylon and its blend fabrics acid anthraquinone blue is mainly used for wool, silk, nylon and its blended fabric dyeing, can also be used for leather, electrochemical aluminum, soap and other coloring, can also be used for wool energy under the dyeing and electrochemical aluminum, soap and other coloring.
production method	the product is obtained by condensation of bromamine acid and aniline in aqueous medium with strontium salt as catalyst. After salting out, filtration, drying, grinding to get the finished product. 211.5 parts of bromamine acid and 182 parts of aniline are condensed in the presence of Na2CO3 and CuSO4, then heated in hydrochloric acid at 90 ℃, filtered, the filter cake is washed with brine, and neutralized with sodium hydroxide solution, filtration and drying gave about 230g of product. (a) condensation of 1-amino -2, 4-dibromo-anthracene-9, 10-dione with aniline, the product, 1-amino-4-aniline-2-bromoanthraquinone, is elevated in phenol under pressure with sodium sulfite. (B) 1-amino-4-bromo-9, 10-dioxo-9, 10-dihydroanthracene-2-sulfonic acid (sodium) copper salts in aqueous media are used as catalysts for the condensation of aniline. bromine (100%), 585 sodium carbonate (98%), 650 aniline (99%), 530 hydrochloric acid (31%) 813
