Disperse Red 60

Chemical properties

deep red powder

The Uses of Disperse Red 60

Disperse Red 60 can be used as anthraquinone disperse dyes.

Preparation

In alkaline medium 1-Amino-2-bromo-4-hydroxyanthracene-9,10-dione?and phenol condensation

General Description

Fine deep-red powder with white specks.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

An amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for Disperse Red 60 are not available. Disperse Red 60 is probably combustible.

Flammability and Explosibility

Non flammable

Synthesis

1-Amino-4-hydroxy-2-phenoxyanthraquinone is prepared from 1-amino-2-chloro- (or -2-bromo-) 4-hydroxyanthraquinone and phenolate. This process was improved .

Properties and Applications

Bright red blue light. 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, weeks of high temperature and high pressure, the dyeing temperature is 125 ~ 130 ℃, good levelness. Dye polyester/ Wool blended fabric of wool with less color . 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 slow. Good levelness, but dye deep the gender is poorer. Three vinegar is dyed fiber dyed deep sex is better. Dyeing nylon is blue color, the dyeing speed is slow, levelness and dye deep sex medium. So when a black silk ribbon with colored light blue, the dyeing rate is low, soaping fastness is bad two 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 colored light slant blue:
