Leuco Sulphur Blue 15 Chemical Properties,Uses,Production

Preparation

8-Amino-5-(4-hydroxyphenylamino)naphthalene-2-sulfonic acid?and aqueous Sodium polysulfide heating, in 107 ~ 108 ℃ under reflux 2 4 hours, will be part of the precipitation in the Sodium sulfide of dye solution, blowing air redeposition. This indophenol?is from?8-Amino-5-nitronaphthalene-2-sulfonic acid?and where did?5-Aminonaphthalene-2-sulfonic acid?and where did?4-Aminophenol?with Sodium hypochlorite oxidation of mixture, then use Sodium sulfide reduction and have to.
