Vat Blue 43 Chemical Properties,Uses,Production
Chemical Properties
Reddish light dark blue powder. Insoluble in water and alcohol, soluble in sodium sulfide solution, yellowish green. Yellowish orange in alkaline reducing solution; greenish yellow in acidic reducing solution; dark blue in concentrated sulfuric acid, produces blue precipitate after 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.
