Chemical Properties:

  1. The chemical name of Bromaminic acid is 1-amino-4-bromo-2-sulfonic acid anthraquinone, which is a dye intermediate, used in the preparation of acidic anthraquinone dyes, such as weak acid brilliant blue R, reactive brilliant blue M-BR And brilliant blue KGR and so on.
  2. Bromaminic acid is red needle-like crystals. Dissolved in water.
  3. Bromaminic acid is produced by the bromination of 1-aminoanthraquinone-2-sulfonic acid. The raw material of bromamic acid, 1-aminoanthraquinone-2-sulfonic acid, can be obtained from 1-aminoanthraquinone, sulfonated with 20% fuming sulfuric acid or sulfonated with chlorosulfonic acid; it can also be obtained from 1-amino-2-Chemicalbook It is derived from bromoanthraquinone sulfide, oxidation and hydrolysis. Raw material consumption quota: 1-aminoanthraquinone (industrial product) 815kg/t, oleum (containing SO320%) 628kg/t, bromine (99%) 483kg/t.
