12236-00-9 Usage
Preparation
2,6-Dichioro-4-nitroaniline diazo, and N,N-bis(2-hydroxyethyl)-3-chlorobenzenamine?coupling .
Properties and Applications
red light brown. Deep dark brown powder. Used for polyester and their blended fabric dyeing and printing, colored light for yellow brown, can also be used to vinegar fiber, polyamide, three vinegar fiber. For dyed red orange vinegar fiber, polyamide fiber dyed red for deep brown. In artificial light, polyester dyeing things a little red, vinegar fiber and three vinegar fiber is red, polyamide fiber dyeing things a little colourful. Also will dye fur and so on the textiles.

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.
