12226-48-1 Usage
Uses
Used in Textile Industry:Reactive Yellow 18 is used as a dye for cotton or viscose fibers. It is suitable for various dyeing processes, including rolling, piling, and roll dyeing. It can also be used for direct discharge printing on cotton or viscose fibers, as well as for silk or viscose filament fabric and printing.
Standard:
Reactive Yellow 18 has the following standards for various properties:
Light Fastness: ISO 6
Oxygen Bleaching: 4 (red)
Perspiration Fastness: 5
Soaping: 4
Fading: 4-5
Stain: 4-5
These standards indicate the dye's performance in terms of colorfastness, resistance to bleaching, and durability in various conditions.
Preparation
2-Aminobenzene-1,4-disulfonic acid and 2,4,6-Trichloro-1,3,5-triazine first condensation, and 2,4-Diaminobenzenesulfonic acid second condensation, its product diazo, and 1-(3-Sulfophenyl)-3-methyl-5-pyrazolone?coupling, and then salting-out.Standard

6Check Digit Verification of cas no
The CAS Registry Mumber 12226-48-1 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 6 respectively; the second part has 2 digits, 4 and 8 respectively.Calculate Digit Verification of CAS Registry Number 12226-48:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*4)+(1*8)=71
71 % 10 = 1
So 12226-48-1 is a valid CAS Registry Number.
