Description
Reactive Black 1 is a dark brown, evenly powdered dye with a solubility of 70 g/L at 50°C. It exhibits strong color properties, turning blue in concentrated sulfuric acid and purple when diluted. It also shows color changes in the presence of rare hydrochloric acid and sodium hydroxide solutions.Uses
Used in Textile Industry:Reactive Black 1 is used as a dye for cotton, hemp, polyamide fiber, and viscose fabric in the textile industry. It is particularly suitable for printing and dyeing applications due to its strong color properties and solubility.
Standard:
Reactive Black 1 meets the following standards in terms of light fastness, oxygen bleaching, perspiration fastness, soaping, fading, and stain:
Light Fastness: ISO 6
Oxygen Bleaching: 4-5
Perspiration Fastness: 4-5
Soaping: 3-4 (green)
Fading: 4-5
Stain: 5(5100℃)
Fading: 4-5
Stain: 4-5
These standards indicate the dye's performance and durability under various conditions, making it a reliable choice for textile applications.
Preparation
4-Amino-3-hydroxy-7-nitronaphthalene-1-sulfonic acid diazo, and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling, and 2,4,6-Trichloro-1,3,5-triazine condensation, again ammoniation, make its forming metal complex (metal is the mixture of cobalt and chromium, also can use when complexation 2-Hydroxybenzoic acid).Standard

6Check Digit Verification of cas no
The CAS Registry Mumber 12236-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 12236-77:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*7)+(1*7)=80
80 % 10 = 0
So 12236-77-0 is a valid CAS Registry Number.
