Acid Blue 25 Use and Manufacturing
Taking bromamine acid and aniline as raw materials, in an aqueous medium, the product is obtained by condensation with catfish salt as a catalyst. The finished product is obtained by salting out, filtering, drying and crushing. . 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°C, filtered, the filter cake is washed with brine, then neutralized with sodium hydroxide solution, filtered and dried to obtain the product About 230g.
Acid anthraquinone blue is mainly used for the dyeing of wool, silk, nylon and its blended fabrics, and can also be used for the dyeing of leather, aluminum, soap, etc. Mainly used for dyeing silk, wool and nylon; mainly used for dyeing silk, wool, nylon and their blended fabrics
