Copper, 5-[(4-hydroxyphenyl)amino]-8-(phenylamino)-1-naphthalenesulfonic acid-sodium polysulfide condensate complexes, leuco derivs. химические свойства, назначение, производство
Подготовка
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 greenСвойства и приложения
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.| Standard | Acid Resistance | Alkali Resistance | Light Fastness | Fulling | Persperation Fastness | Soaping | |
