Reactive Turquoise Blue Kn-G Chemical Properties,Uses,Production

Chemical Properties

Blue powder. The solubility in water (20℃) is 100g/L. The aqueous solution is lake blue, add 1mol/L sodium hydroxide, the color remains unchanged, then add the insurance powder and warm to purple, then add sodium perborate to return to the original color, a little lighter. It is blue in concentrated sulfuric acid, and the color is unchanged after dilution; it is green in concentrated nitric acid, and the color is slightly lighter after dilution.

Uses

Reactive Blue 21 is a phthalocyanine dye that can be decolorized by fungal strains isolated from contaminated soil.

Preparation

Copper phthalocyanine use chlorosulfonic and chlorinated and sulfones chlorosulfonated, and registration, 2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate condensation.

Properties and Applications

colourful green light blue. Blue powder. The strong sulfuric acid in blue, diluted for blue still; In nitric acid for green, diluted into a green light. Water solution is blue lake, add 1 Moore sodium hydroxide solution is still lake blue; Continue to join insurance powder and warm, into purple; Add a boric acid sodium return to a lake blue, colour and lustre is a little shallow. Used for cotton, linen, silk, polyamide fiber of knot dyeing and roll dye, also can be used in viscose fabric printing.
