EPA Substance Registry System

Benzenesulfonic acid, 3,3'-[carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)azo]]bis[5-[(3-aminobenzoyl)amino]-4-methyl-, disodium salt (6420-36-6)

3,3'-[Carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)azo]]bis[5-[(3-aminobenzoyl)amino]-4-methylbenzenesulfonic acid sodium] salt Usage And Synthesis

Preparation

3-Amino-4-methyl-5-(3-aininobenzamido)benzenesulfonic acid nitro reduction for the yankees nitrogen, with sodium sulfite chlorine processing, make it become the amino sulfonic acid. Product diazo, and 2-Amino-4-methylanisole coupling, and then make the light gasification, finally hydrolysis amino sulfonic acid base

Properties and Applications

yellow orange. Soluble in water for red light yellow, slightly soluble in ethanol for green light yellow. The strong sulfuric acid for dark purple, diluted for yellow olive. The dye solution to join strong hydrochloric acid for dark olive brown, have precipitation; Add thick sodium hydroxide solution the same color. Used for the cellulose fibre, silk dyeing, also can be used for leather color. Exhaust dyeing, levelness general, dye cellulose fiber, 80 ℃ maximum affinity.
