disodium [mu-[[7,7'-iminobis[4-hydroxy-3-[[2-hydroxy-5-(N-methylsulphamoyl)phenyl]azo]naphthalene-2-sulphonato]](6-)]]dicuprate(2-) Chemical Properties,Uses,Production
Preparation
3-Amino-4-hydroxy-N-methylbenzenesulfonamide (2 Moore) diazo, and Bis(4-hydroxy-2-sulfonaphthalene-7-yl)amine coupling, and then use the ammonia containing copper sulfate solution processing, make it a double copper complex.
Properties and Applications
blue purple. Dark purple powder. Soluble in water solution for purple, soluble in ethanol for red light purple, insoluble in other organic solvents. The strong sulfuric acid dyes for black light purple, diluted into red wine. The dye solution to join strong hydrochloric acid into Claret, precipitation; Add thick sodium hydroxide solution still for purple, have precipitation. Water-soluble general, acid, alkali and sensitive fights. In dyeing copper and iron ion colored light basic unchanged. Used for cotton, viscose, silk dyeing and printing, also can be used for leather and paper shading, its heavy metal salt can be used as organic pigments.
