6408-72-6 Usage
Description
Disperse Violet 26 is a red light purple dye with a brown-red powder form, soluble in alcohol. It has a colorless appearance in strong sulfuric acid and turns red when diluted, indicating a yellow light. This dye is not sensitive to calcium and magnesium ions in dyeing, but it can be slightly influenced by iron ions and significantly affected by copper ions. The appropriate pH value for the dye bath is between 3 and 8, and it is not alkali-resistant in dyeing and printing. The dye produces a red light purple color, making it suitable for dyeing polyester/cotton blended fabrics and offering good color fastness to dry.
Uses
Used in Textile Industry:
Disperse Violet 26 is used as a dye for polyester/cotton blended fabrics due to its good color fastness to dry and suitability for high temperature high pressure and hot melt dyeing methods. The hot melt temperature for this dye is between 210 and 220 degrees Celsius.
Used in Polyester Fabric Weaving:
Disperse Violet 26 is used as a dye in polyester fabric weaving, providing a colored light similar to that of polyester. However, it is not suitable for dyeing two vinegar fiber, polyamide fiber, and acrylic.
Used in Direct Printing on Polyester Fabric:
Disperse Violet 26 is used in direct printing on polyester fabric, but it cannot be used for printing the impression of the discharge.
Standard:
Disperse Violet 26 meets the following standards for various fastness and performance tests:
Ironing Fastness: ISO 4
Light Fastness: ISO 3
Persperation Fastness: ISO 6
Washing Fastness: ISO 5
Fading: ISO 5
Stain: ISO 4-5
Note: Disperse Violet 26 shares the same chemical structure with another dye mentioned in the materials, but the name of that dye is not provided.

Check Digit Verification of cas no
The CAS Registry Mumber 6408-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6408-72:
(6*6)+(5*4)+(4*0)+(3*8)+(2*7)+(1*2)=96
96 % 10 = 6
So 6408-72-6 is a valid CAS Registry Number.

Paragraph 0036; 0037; 0038; 0043; 0048; 0053; 0054, (2018/11/03)
The invention discloses a solvent red 59 synthesis process, in order to 1, 4 - dinitro - 2, 3 - two chloroanthraquinone, phenol sodium as raw materials, the organic solvent in the presence of O-chlorobenzene to generate a condensation reaction to produce 1, 4 - dinitro - 2, 3 - [...] anthraquinone, 1, 4 - dinitro - 2, 3 - [...] anthraquinone and then by further reduction to produce 1, 4 - diamino - 2, 3 - [...] anthraquinone. Because of the 1, 4 - dinitro - 2, 3 - dichloro anthraquinone activity and low 1, 4 - diamino - 2, 3 - dichloro anthraquinone of high activity, the invention the reaction is easy to carry out, so greatly shortens the reaction time; and the reaction less side reaction, high yield, insoluble matter is greatly reduced, while at the same time, this synthetic route will not produce a large amount of salt-containing waste water, the process is relatively clean and environmental protection.
