| | Reactive Blue 49 Usage And Synthesis |
| Chemical Properties | Dark blue powder. Easily soluble in water, solubility in water is 200g/L (20℃), solubility in water at 50℃ is more than 200g/L. It is reddish blue in concentrated sulfuric acid; blue in dilute alkali solution. | | Uses | Reactive Blue 49 is used for dyeing cotton and viscose fibers, as well as printing on their fabrics. It exhibits excellent color fastness and is an important blue dye. | | Preparation | 1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and 3,5-Diamino-2,4,6-trimethylbenzenesulfonic acidcondensation, again with 2,4,6-Trichloro-1,3,5-triazine condensation, and finally 3-Aminobenzenesulfonic acid condensation. | | Properties and Applications | red light blue. Blue powder, the strong sulfuric acid for red light blue; In a dilute alkali solution to blue. In 20 ℃ solubility of 200 g/L; 50 ℃ when more than 200 g/L solubility. The dyed fabric for the red light blue light. The reactive dyes low, low affinity, solid color rate is 60%. Neutral and alkaline are not suitable for white.
