| Hazard Information | Back Directory | [Chemical Properties]
Reddish-dark blue powder. Insoluble in water and alcohol, readily soluble in sodium sulfide solution, giving a yellowish-green color. It turns yellow-orange in alkaline reducing solutions and greenish-yellow in acidic reducing solutions. It turns dark blue in concentrated sulfuric acid, producing a blue precipitate upon dilution. | [Preparation]
3-(4-Hydroxyanilino)carbazole in 107 ℃ in Butanol sodium polysulfide solution reflux heating 24 hours, and then with sodium nitrite short time heating, steam out of Butanol, through the air and add salt to make dye completely precipitated out. This indophenol is by carbazole and nitroso phenol in concentrated sulfuric acid in – 20 to 23 ℃ condensation, then reduction and have to (BIOS983, 71 -74). To cure solution is to add 3 – methyl – 4 ‘- hydroxy – 4 -aminodiphenylamine, 4, 4’ – dihydroxydiphenyl aniline and phenol , improved the performance of the dye (BIOS983, 75- 81). Note: use with C.I. leuco sulfur dye similar method, some the structure of the dyes can be converted into the leuco compound. | [Properties and Applications]
red light blue to red light navy blue. In concentrated sulfuric acid for the faint blue, blue precipitation after dilution.
