C.I.Leuco Sulphur Green 3,C.I.53570,CAS 12262-33-8,Ecosol Liq Green IGCFN,Sodyesul Liquid Green NCF

CAS Registry Number:12262-33-8

Manufacturing Methods :  8-Anilino-5-(4-hydroxyanilino)-1-naphthalenesulfonic acid in the presence of Copper sulfate monohydrate with Sodium polysulfide solution heating, in 106 ℃ under reflux 24 hours, and then is in 60 ~ 80 ℃ blowing air precipitation out dye. This indophenol is by 8-(Phenylamino)naphthalen-1-ol and where did 4-Aminophenol with Sodium hypochlorite oxidation of mixture, then use Sodium hydroxide and reduction. In the fusion of Copper sulfate monohydrate increase the amount of income dyes to color yellow green, reduce the amount of Copper sulfate monohydrate, the dye to color blue light green

Properties and Applications: green. Aquamarine blue powder. Slightly soluble in water. In the Sodium sulfide solution solubility is good, for olive; In concentrated sulfuric acid for dark blue, dark blue precipitation after dilution.
