Reactive Violet M-5R - Physico-chemical Properties
| Molecular Formula | C20H16N3Na3O15S4 |
| Molar Mass | 735.58 |
| Appearance | Form Solid, color Dark Blue to Black |
| Storage Condition | Amber Vial, Refrigerator, Under inert atmosphere |
| Stability | Light Sensitive |
| Physical and Chemical Properties | Chemical properties purple brown powder. The solubility in water (50 ℃) is 100g/L. The aqueous solution is red-purple, and the addition of 1mol/L sodium hydroxide solution is still red-purple. After adding sodium hydrosulfite and warming, it is colorless, and then adding sodium perborate cannot restore the original color. It is blue red in concentrated sulfuric acid and rose red after dilution. It is orange-red in concentrated nitric acid and light reddish brown after dilution. |
| Use | Use Active purple KN-4R can be used for dyeing cotton and viscose fibers. Various dyeing methods are applicable and have high affinity. It is also used for direct and anti-dyeing printing of cotton and viscose fabrics. It can also dye nylon and silk. Used for dyeing and printing of cotton, hemp, silk and other fabrics |

Reactive Violet M-5R - Production method
Using p-(2-sulfate ethyl sulfone group) aniline and acetyl H acid as raw materials, the p-(2-sulfate ethyl sulfone group) aniline is first diazotized, then coupled with acetyl H acid, and then oxidized and complexed to obtain the product. The finished product is salted out, filtered and dried..
Add 300L of water and 145kg of p (2-sulfate ethyl sulfone group) aniline into a diazo pot, stir, add 45kg of soda ash, control the pH value to 7.5, and dissolve all the materials. Add 130kg of hydrochloric acid, cool to 0-2 ℃, add 30% sodium nitrite solution, maintain 5-8 ℃, add stirring for 30min, neutralize with soda ash to pH 4.
Add N-acetyl H acid solution (obtained by acetylation of 170.5kg H acid) into the coupling pot, cool to 5 ℃, add the above diazo solution, stir for 1h after adding, neutralize with 20% soda ash to a pH value of 6-6.7.
Add 1kg of 12% copper sulfate disodium hydrogen phosphate solution into the coupling pot and stir for 30min. 550kg of hydrogen peroxide was added at 25-30 ℃ for 3h, and stirred for 4h to the end point. Then add potassium chloride to salt out, stir for 8 hours, filter and dry to obtain the finished product.
