Name:C.I.Disperse Red 71

Molecular Structure:

C.I.Disperse Red 71,CAS 12223-37-9,331.32,C20H13NO4

Molecular Formula:C₂₀H₁₃NO₄

Molecular Weight: 331.32

CAS Registry Number: 12223-37-9

Manufacturing Methods : 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.
