disodium 2'-[4-[[1-hydroxy-7-(phenylamino)-3-sulphonato-2-naphthyl]azo]phenyl]-6-methyl[2,6'-bibenzothiazole]-7-sulphonate Chemical Properties,Uses,Production

Preparation

p-Methylaniline (2 Moore) and sulfur (4.5 atomic ratio) in 200 ~ 280 ℃ heat, with hair smoke products have been Primulin alkali. Its product (C.I. Direct Yellow 59, C.I. 49000) diazo, in alkaline conditions and 4-Hydroxy-6-(phenylamino)naphthalene-2-sulfonic acid coupling. In some brands of C.I. Direct Yellow 59?can all or part of the content and dehydrogenation was 2-(2-(4Aminophenyl)benzo[d]thiazol-6-yl)-6-methylbenzo[d]thiazole-7-sulfonic acid instead.

Properties and Applications

dark brown. Soluble in water for yellow olive brown, soluble in alcohol. For the strong sulfuric acid in purplish red, yellow light is palm diluted to olive. The dye solution to join strong hydrochloric acid have yellow olive precipitation; Add thick sodium hydroxide solution with olives brown precipitation.
