Description
Disperse Brown 1 is a red light brown, deep dark brown powder that is commonly used as a dye for various types of fabrics, including polyester, blended fabrics, vinegar fiber, polyamide, and triacetate fiber. It is known for its ability to produce yellow brown shades and can also be used to dye fur and other textiles.
Uses
Used in Textile Industry:
Disperse Brown 1 is used as a dye for polyester and blended fabrics, providing a yellow brown color. It is also used for dyeing vinegar fiber, polyamide, and triacetate fiber, resulting in a deep brown color for red orange vinegar fiber and polyamide fiber.
Used in Artificial Light:
In artificial light, polyester dyeing with Disperse Brown 1 appears slightly red, while vinegar fiber and triacetate fiber appear red, and polyamide fiber dyeing appears slightly colorful.
Standard:
Disperse Brown 1 has been tested for various fastness properties, including ironing, light, perspiration, and washing fastness. The results are as follows:
Ironing Fastness: ISO 4-5, AATCC 4-5
Light Fastness: ISO 4, AATCC 4
Perspiration Fastness: ISO 5-6, AATCC 5
Washing Fastness: ISO 5, AATCC 5
Fading and Staining:
The fading and staining properties of Disperse Brown 1 are also evaluated, with the following results:
Fading: ISO 4-5, AATCC 5
Staining: ISO 5, AATCC 5
Overall, Disperse Brown 1 is a versatile dye with a range of applications in the textile industry, particularly for polyester and blended fabrics, as well as other types of fibers. Its fastness properties make it a reliable choice for various dyeing processes.

Check Digit Verification of cas no
The CAS Registry Mumber 12236-00-9 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, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12236-00:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*0)+(1*0)=59
59 % 10 = 9
So 12236-00-9 is a valid CAS Registry Number.

Clean preparation method for weakly alkaline arylamine azo disperse dye
-
Paragraph 0047; 0048; 0049; 0050; 0051; 0057; 0058, (2017/01/02)
The present invention provides a clean preparation method for weakly alkaline arylamine azo disperse dye. The method is characterized in that when a weakly alkaline arylamine diazonium double salt solid is coupled with a coupling component, the coupling component is pretreated to obtain a fine particle dispersion to be coupled with the weakly alkaline arylamine diazonium double salt; and the generated disperse dye is precipitated from the coupling system and is filtered and dried, thereby obtaining the weakly alkaline arylamine azo disperse dye. According to the preparation method provided by the present invention, by using a stable double salt structure of a diazonium salt, during the coupling, the process of adding acid for dissolution can be omitted; the coupling is performed at the normal temperature, and extra cooling is not required; and the method has a broad application prospect.
