12223-37-9 Usage
Preparation
In alkaline medium 1-Amino-2-bromo-4-hydroxyanthracene-9,10-dione?and phenol condensation.
Properties and Applications
Purple powder evenly. Soluble in 50% of acetone for red, soluble in four hydrogenated naphthalene and xylene. The strong sulfuric acid solution for yellow, the alkali sensitive. Dyeing met in the copper, iron ion color becomes shallow. This product used for polyester and their blended fabric dyeing and printing, for the bright red light blue light, the sun good fastness, with high temperature and high pressure, the temperature dyeing of 125 to 130 ℃, good levelness. dyed polyester / wool blended fabrics of wool stain less. The sublimation fastness is poorer, melt method only appropriate spell dye light color. When two vinegar fiber dyed with polyester similar color shade, the dyeing speed is slow, good levelness, single dye deep the gender is poorer. Three vinegar is dyed fiber dyed deep sex is good. Nylon is colored light blue dye, the dyeing speed is slow, levelness and dye deep sex medium. When a blue dye acrylic light, the dyeing rate is low, soaping fastness is poorer. This product can be used for nylon polyester fabric or the direct printing, be not white color, suitable for transfer printing. To calcium, iron ion is very sensitive, dye bath these ions are slant blue light. And C.I. Disperse red 60, 83 the same chemical structure scattered red.
Check Digit Verification of cas no
The CAS Registry Mumber 12223-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12223-37:
(7*1)+(6*2)+(5*2)+(4*2)+(3*3)+(2*3)+(1*7)=59
59 % 10 = 9
So 12223-37-9 is a valid CAS Registry Number.
