| Molecular Formula | C20H20N3NaO11S3 |
| Molar Mass | 597.56 |
| Physical and Chemical Properties | Chemical properties red powder. The solubility in water is 120g/L (20 ℃) and 150g/L (80 ℃). When dyeing, the iron ion color light is slightly dark, and the copper ion color light turns dark. The dye has high reactivity and medium affinity. |
| Use | Use Active orange KN-5R is used for dyeing cellulose fibers such as cotton and viscose fibers. It can be dyed by exhaustion or continuous dyeing. It is also used for one-phase or two-phase printing of cotton and viscose fabrics. This product can be used for monochromatic use and also for blackening. if it is matched with active black KN-B (C.I.Reactive Black 5), it can improve its blackness. |
| Raw Materials | SULFATE STANDARD 2-[(4-Aminophenyl)sulfonyl]ethyl hydrogen sulfate 2-Acetamido-8-naphthol-6-sufonic acid (N-acetyl gamma acid) |
| EPA chemical information | 2-Naphthalenesulfonic acid, 6-(acetylamino)-4-hydroxy-3-[[4-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]azo]-, disodium salt (20262-58-2) |
Using p-(2-sulfate ethyl sulfone group) aniline and N-acetyl & gamma; acid as raw materials, the former is first diazotized, and then coupled with the latter to obtain the product. The finished product is salted out, filtered and dried.
