Physical and Chemical Properties | Yellow powder. The solubility in water (50 °c) was 40g/L. The aqueous solution was yellow, which was slightly dark and red when added with 1mol/L sodium hydroxide, followed by addition of sodium hydrosulfite and warming to colorless, and then added with sodium perborate, which could not return to the original color. In concentrated sulfuric acid, it is in vermilion and turns yellow after dilution. In concentrated nitric acid in a purple red, diluted to yellow. |

Use | active yellow K-RN is suitable for dyeing cotton and viscose fiber with high affinity, general fixation rate, chlorine bleaching resistance, light fastness was 6-7. Also used for cotton, viscose fabric printing, mainly used for direct printing of cotton fabrics, and with the reactive brilliant orange K-G, reactive brilliant orange K-R color matching, printing a variety of red and yellow; And reactive brilliant blue X-BR dark green. It is not suitable for direct printing on the yellow cloth of the phenol as, because of the staining weight, it is not easy to wash off. Can be printed with soluble vat dyes, such as with the soluble anthracene green IB color, can be better fastness Green. It is also used for dyeing of vinylon fiber and direct printing of cotton/cotton (50:50) Fabric. The color yield and brightness of the two fibers are basically close. When used for dyeing and printing of viscose fiber blended fabrics, acrylic fiber, triacetate fiber and polyester are not stained with color, diacetate fiber and nylon are stained with color, and wool is stained with serious color. It is used for two-bath dyeing of polyester/cotton blended fabric, which can be combined with reactive Alexandrite K-GL. used for dyeing and printing of cotton, viscose, silk and other fabrics |
production method | amino C acid, M-acetamidoaniline, cyanuric chloride and chlorine water are used as raw materials, first, the amino C acid is diazotized and then coupled with M-acetamidoaniline; Then the first condensation is carried out with cyanuric chloride, and then the second condensation is carried out with ammonia water, and the final product is obtained by salting out, filtering and drying.. |
