| Hazard Information | Back Directory | [Preparation]
4-(4-(Phenylamino)phenylimino)cyclohexa-2,5-dienone with Sodium polysulfide solution at 122 ~ 124 ℃ heating 36 hours, after diluted with air precipitation (BIOS 1155, – 22). This indophenol?by Diphenylamine and 4-Nitrosophenol in sulfuric acid in the condensation, in 116 ~ 117 ℃ reflux get a brilliant color of dye. | [Properties and Applications]
dark blue to blue. Navy blue powder. Insoluble in water, moderate soluble in sodium sulfide solution, for green yellow. In concentrated sulfuric acid to green light blue, dilution of dark after precipitation. Dyeing content in alkaline insurance powder for green light yellow, after oxidation can restore the original colour and lustre; In Sodium hypochlorite solution all fade, join concentrated sulfuric acid into black. Mainly used for cotton, hemp, viscose and vinylon/cotton blended fabric dyeing, also can be used for leather and paper dyeing.
