Oxidierte sulfurierte Aminophenole Chemische Eigenschaften,Einsatz,Produktion Methoden
synthetische
With or without with?a?phenol?and?4-(4-Hydroxyphenylamino)phenol??4-(Naphthaleti-2-ylamino)phenol?in Sodium polysulfide of tert – Butanol solution, 108 ℃ reflux heating 30 hours, then use Sodium nitrite oxidation, water steam distillation out tert – Butanol, filter ceding dye crude products, with dilute hydrochloric acid treatment into final product. The dye in the cellulose fiber dyeing, its resistance to chlorine bleaching fastness is better than the?2,4-Dinitrophenol?and by the Sulphur Black (C.I. Sulphur Black 1?and related dye)
Properties and Applications
blue black. In the Sodium hydroxide solution for gray, dilution after black precipitation; In concentrated sulfuric acid for blue, dilution after black precipitation.
