| Physical and Chemical Properties | Red sauce color powder. The solubility in water (50 °c) was 90g/L. The aqueous solution was bright red, and 1mol/L sodium hydroxide solution was added to turn orange red, followed by addition of sodium hydrosulfite and warm to orange, with slight precipitation, followed by sodium perborate to turn light yellow. It was purplish red in concentrated sulfuric acid, and turned pink after dilution. Dark red in concentrated nitric acid, diluted to red. |

61951-82-4 - Reference Information
| Use | reactive red KE-3B is mainly used for dyeing cotton and viscose fiber with high dyeing rate and color fixation rate of 78%. It is also used for direct printing of cotton and viscose fabrics, with a high fixation rate of nearly 90%. The dye is pure in color, good in dyeing depth and high in utilization. It can also be used for dyeing polyester/cotton blended fabrics with disperse dyes in the same bath. It is mainly used for dyeing and direct printing of cotton and viscose fibers, and is suitable for dyeing polyester/cotton and polyester/viscose blended fabrics |
| production method | with H acid, cyanuric chloride, p-phenylenediamine and O-aminobenzene sulfonic acid as raw materials, the product is obtained by condensation with p-phenylenediamine, diazotization of O-aminobenzene sulfonic acid, and coupling with the condensate.. |
