REACTIVE BLUE 19 Usage And Synthesis

Chemical Properties

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.

Uses

Reactive Blue 19 is an organic dye used in the textile industry, and a water pollutant. Decolourization of Reactive Blue 19 is typically achieved via photodegradation with photocatalysts such as bismuth oxo citrate. Dyes and metabolites, Environmental Testing

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.

General Description

Fine blue-black powder.

Air & Water Reactions

Water soluble.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition REACTIVE BLUE 19 emits very toxic fumes of sodium oxide, nitrogen oxides and sulfur oxides.

Fire Hazard

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
