Description
Reactive Black 8 is a blue ash, black powder dye that exhibits unique color-changing properties when exposed to different chemicals. It is known for its strong colorfastness and resistance to fading, making it a popular choice for various applications in the textile industry.Uses
Used in Textile Industry:Reactive Black 8 is used as a dye for cotton, viscose, linen, silk, polyamide fiber, and wool. Its application reason is due to its strong colorfastness and resistance to fading, as well as its ability to produce deep, rich black shades.
Standard:
Reactive Black 8 meets the following standards for various properties:
1. Light Fastness: ISO 6 (grey)
2. Oxygen Bleaching: ISO 3 (green)
3. Perspiration Fastness: ISO 5
4. Soaping: ISO 4-5 (green)
5. Fading: ISO 3
6. Stain: ISO 5
7. Fading: ISO 6
These standards indicate the dye's performance in terms of colorfastness, resistance to fading, and compatibility with various washing and bleaching processes.
Preparation
2-Amino-4-nitrophenol diazo, and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, chromium complexation, and 2,4,6-Trichloro-1,3,5-triazine condensation, with four ammonia, and salting-out.Standard

The CAS Registry Mumber 12225-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.Calculate Digit Verification of CAS Registry Number 12225-26:
(7*1)+(6*2)+(5*2)+(4*2)+(3*5)+(2*2)+(1*6)=62
62 % 10 = 2
So 12225-26-2 is a valid CAS Registry Number.
