disodium 3,3'-[carbonylbis[imino(3-methoxy-4,1-phenylene)azo]]dibenzoate Chemical Properties,Uses,Production

Preparation

3-Aminobenzoic acid?diazo, and (2-Methoxyphenylamino)methanesulfonic acid coupling, then the water with sulfonic acid base, and then to light gasification.

Properties and Applications

yellow. Yellow brown powder. Soluble in water solution for green light yellow, and adequate soluble in alcohol. The strong sulfuric acid dyes for product red to red light purple, diluted into a weak yellow light olive. The dye solution to join strong hydrochloric acid for dark brown, and precipitation; Add thick after sodium hydroxide solution colored light unchanged, precipitation. Water-soluble, sensitive fights. Dyeing meet copper, iron ion colored light basically unchanged, more sensitive to that fights. Used for cotton, viscose, silk, rayon blended dyeing, but not used for printing. Also used for paper, leather dyeing
