Reactive Yellow 1 - Physico-chemical Properties
| Molecular Formula | C19H13Cl4N8NaO7S2 |
| Molar Mass | 694.27 |
| Physical and Chemical Properties | Yellow powder. Solubility (50 C) = 100g/L. It is yellow in concentrated sulfuric acid, dilute sulfuric acid, concentrated nitric acid and dilute nitric acid. The aqueous solution was yellow, and the 1mol/L sodium hydroxide solution was yellow, followed by the addition of sodium hydrosulfite and warming to colorless, and the sodium perborate was still colorless. Resistance to alkaline hydrolysis, not acid hydrolysis. When hard water is slightly sensitive, it should be stained with soft water. It turned red in case of copper ion. |

| use | reactive light yellow X-6G is mainly used for yarn and fabric dyeing of cotton and viscose fibers, with good levelness and wet treatment fastness. It can also dye nylon, silk and wool, and can also be used for printing copper ammonium fiber fabrics. It can also be combined with reactive brilliant blue X-BR to dye various greens for cotton and viscose fiber products. It is KN-G with reactive turquoise blue to dye fruit green for silk silk textiles. |
| production method | using cyanuric chloride, 2, 4-diaminobenzenesulfonic acid and 1-(2 ',5'-dichloro-4 '-sulfophenyl)-3-methyl -5-pyrazolone as raw materials, 2, 4-diaminobenzenesulfonic acid is first condensed with cyanuric chloride, then diazotized, and then with 1-(2',5 '-dichloro-4'-sulfophenyl)-3-methyl -5-pyrazolone coupling, salted out, filtered, and dried to obtain the finished product.. |
