Preparation 2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate (2 Moore) diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling.
Definition ChEBI: Remazole black-GR is a bis(azo) compound with two aryldiazenyl moieties placed at positions 2 and 7 of a multi-substituted naphthalene. It has a role as a dye. It is a bis(azo) compound, a sulfone and an organic sodium salt. It contains a remazole black-GR (4-).
Properties and Applications black. Black powder. The strong sulfuric acid for green, diluted into a brown. The dye solution for blu-ray black, add 1 Moore sodium hydroxide solution no change colour and lustre, continue to join insurance powder and warm, to tan and add a boric acid sodium can’t back to its original colour and lustre. 20 ℃ when solubility of 200 g/L, 80 ℃ the solubility of more than 200 g/L. After dyeing color shade of green light for black, dye bath containing iron ion colored light basic unchanged, contain copper ions colored light red. The dye the affine high, the reaction of the high. 1:1 standard white depth for 3 ~ 4 levels. Used for cotton, viscose, wool and polyamide fiber disseminated, roll the dye, knot dyeing piled up and dyeing of continuous. Can also be used for cotton or viscose fabric printing and dyeing directly the printing and discharge printing
