Disperse Red 9 Usage And Synthesis

Uses

1-Methylaminoanthraquinone is an important intermediate for manufacturing solvent dyes and acid dyes.

Preparation

1-Chloroanthraquinone?or 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid?in pressure and in the presence of antioxidants with Methanamine for processing.

Synthesis Reference(s)

Synthetic Communications, 21, p. 1889, 1991 DOI: 10.1080/00397919108021779

Synthesis

1-Methylaminoanthraquinone, is prepared from anthraquinone- 1-sulfonic acid by replacing SO3H(see page 8), , from 1-chloroanthraquinone by replacing chlorine , , or from 1-nitroanthraquinone by replacing NO2 , .

Purification Methods

Crystallise it to constant melting point from butan-1-ol, then from EtOH. It can be sublimed under vacuum. [Beilstein 7 IV 2574.]

Properties and Applications

Bright red blue light. Soluble in ethanol, acetone and soluble fiber element, slightly soluble in benzene and carbon tetrachloride, insoluble in special solvent, tao. The strong sulfuric acid for brown, for dark orange after diluted. Used for polyester, polyamide fiber, acrylic, acetate fiber and three acetate fiber dyeing, sheepskin and plastic color. Good levelness, improve rate is high.
