12239-34-8 Usage
Description
Disperse blue 79 is a blue-gray powder that is soluble in acetone. It is known for its red light navy blue and navy blue color properties. It is sensitive to alkali and has a dye bath pH of 5-6. This dye is suitable for high temperature and high pressure dyeing, providing a deep color and good sublimation fastness. However, it may not provide the most level dyeing on pieces and may not be the most vibrant for certain types of fibers.
Uses
Used in Textile Industry:
Disperse blue 79 is used as a dye for various types of fibers, including polyester and acrylic, due to its ability to provide a deep color and good fastness properties. It is particularly suitable for high temperature and high pressure dyeing processes.
Used in Dyeing of Iron Ion:
Disperse blue 79 is used as a dye for iron ion, as it has minimal influence on the color.
Used in Dyeing of Copper Ions:
Disperse blue 79 is used as a dye for copper ions, as it has a significant influence on the color.
Used in Three Vinegar Fiber Dyeing:
Disperse blue 79 is used as a dye for three vinegar fiber, providing a slant red light color. However, it is not suitable for two vinegar fiber dyeing.
Used in Printing with Plasma Reactive Dye:
Disperse blue 79 is used in combination with plasma reactive dye for printing, which allows for a change in the color's lightness.

Check Digit Verification of cas no
The CAS Registry Mumber 12239-34-8 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 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12239-34:
(7*1)+(6*2)+(5*2)+(4*3)+(3*9)+(2*3)+(1*4)=78
78 % 10 = 8
So 12239-34-8 is a valid CAS Registry Number.
