dark blue crystalline powder | [Uses]
CI Reactive Blue 19 (CI 61200) is most widely used for dyeing cellulose fibers in exhaustion dyeing, and it gives a brilliant reddish blue shade and excellent lightfastness. | [Preparation]
1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and 2-(3-Aminophenylsulfonyl)ethyl hydrogen sulfate condensation, refined, and then salting-out. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
bright blue. Blue powder, the strong sulfuric acid solution for red sauce, after diluted navy precipitation; In the nitric acid is yellow, diluted still yellow in color. Water solution is blue, with 1 Moore sodium hydroxide solution colored light unchanged, continue to join insurance powder and warm red brown have precipitation; Add a boric acid sodium into shallow purple. 20 ℃ in the more than 150 g/L solubility. After dyeing color shade of blue for colourful, meet iron and copper ions colored light basic unchanged (level 5). The dye the affine high, the reaction of the high, 1/1 of the depth of the standard for 2 levels of white. Used for cotton, viscose fiber disseminated, roll dye, knot dyeing piled up, Continuous pad?staining
