5-[[4-(aminosulphonyl)-2-nitrophenyl]amino]-2-[[4-[[4-(aminosulphonyl)-2-nitrophenyl]amino]phenyl]amino]benzenesulphonic acid Chemical Properties,Uses,Production

Chemical Properties

Brown powder. Soluble in water, no change in color when hydrochloric acid is added to the aqueous solution; the color becomes lighter when sodium hydroxide is added. Greenish yellow in concentrated sulfuric acid, color unchanged after dilution. When stained with copper and iron ions, the color and luster become dark.

Preparation

5-Amino-2-(4-aminophenylamino)benzenesulfonic acid and 4-Chloro-3-nitrobenzenesulfonamide(2 Moore) condensation.

Properties and Applications

brown. Brown powder, soluble in water. The strong sulfuric acid dyes for green light yellow, no change after diluted; After add sodium hydroxide color becomes shallow. Levelness and discharge good sex, in dyeing copper and iron ion color shade darker. Used for wool, silk and wool products dyeing, general is not used for printing.
