| Hazard Information | Back Directory | [Uses]
Reactive Blue 104 can be used for dyeing cotton and viscose fibers, exhibiting good dyeing performance and fastness, and is suitable for various dyeing methods. It can be used alone to dye deep blue, or to blend with other colors such as dark gray and navy blue. It is also used for direct and resist printing on cotton and viscose fabrics, as well as for dark resist discharge printing on polyester-cotton fabrics. It can also be used for dyeing vinylon. | [Preparation]
Benzaldehyde with sulfuric acid and nitric acid nitrification, use the method reduction, with vinegar anhydride acylation, with sulfuric acid nitrification and nitric acid, hydrochloric acid and iron powder reduction, first and 4-Formylbenzene-1,3-disulfonic acid condensation, again with 3-Amino-4-hydroxybenzenesulfonic acidcondensation, copper complexation, then with 5-Chloro-2,4,6-trifluoropyrimidine condensation. | [Properties and Applications]
bright blue. Blue-black powder, water solution is bright blue, poor solubility. The strong sulfuric acid for navy, diluted for brown; In the nitric acid is shallow brown, precipitation, diluted into light yellow. The dye water solution is colourful blue, with 1 Moore sodium hydroxide solution is still bright blue; Continue to join insurance powder and warm, into a colourless; Add a boric acid sodium can’t restore the original colour and lustre. Used for cotton, wool, linen, silk and viscose fiber dyeing and printing, also can be used for polyester/cotton blended fabric dyeing of a bath.
