Sulphur Green 3
Name:C.I.Sulphur Green 3,C.I.53570
Molecular Structure:
C.I.Sulphur Green 3,C.I.53570,CAS 1327-73-7,Sulphur Green 2B,Sulphur Brilliant Green G,Sulphur Brilliant Green GB
CAS Registry Number:1327-73-7
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. Dyeing content in alkaline insurance powder solution for dark orange, after oxidation can be restored to the original colour and lustre; In Sodium hypochlorite solution all fade, join concentrated sulfuric acid into dark blue. Suitable for cotton, hemp, viscose and vinylon/cotton blended fabric dyeing, also used for cotton direct printing, a few used in leather and paper dyeing.
