Synthesis
1-Methylamino-4-(2-hydroxyethylamino) anthraquinone is prepared (in admixture with symmetrical and half-reacted exchange products) by replacement of NH2 from 2,3-dihydro-1,4-diaminoanthraquinone with a mixture of methylamine and ethanolamine .
Properties and Applications
Bright blue. Soluble in acetone, ethanol, soluble fiber element and benzene, slightly soluble in carbon tetrachloride, insoluble in special solvent, tao. The strong sulfuric acid for brown, diluted into a dark red. Suitable for vinegar fiber and three vinegar fiber, polyamide, acrylic dyeing and printing. Although can be used for polyester, but lifting force and the sun to prison Degree is not good. Can be used for the thermoplastic color. exist
