| | Disperse Red 9 Usage And Synthesis |
| Chemical Properties | Red powder. Soluble in acetone, ethanol, ethylene glycol ether, linseed oil. Slightly soluble in benzene, carbon tetrachloride. Insoluble in Staudt's solvent. Brown in concentrated sulfuric acid, turns dark orange when diluted. | | Uses | 1-Methylaminoanthraquinone is an important intermediate for manufacturing solvent dyes and acid dyes. | | Preparation | 1-Chloroanthraquinoneor 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acidin pressure and in the presence of antioxidants with Methanamine for processing. | | Synthesis Reference(s) | Organic Syntheses, Coll. Vol. 3, p. 573, 1955
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.
