disodium 2'-[4-[[2,6-dihydroxy-3-[(4-sulphonatophenyl)azo]phenyl]azo]phenyl]-6-methyl[2,6'-bibenzothiazole]-7-sulphonate Chemical Properties,Uses,Production

Preparation

4-Aminobenzenesulfonic acid diazo, and Resorcinol coupled;p-Methylaniline (2 Moore) and sulfur (4.5 atomic ratio) in 200 ~ 280 ℃ heat, Sulfonated with fuming sulfuric acid alkali obtained primulin. Its product (C.I. Direct Yellow 59, C.I. 49000) diazo, and the generation of single accidentally coupled nitrogen compounds.

Properties and Applications

yellow light brown. Soluble in water for orange brown, easily soluble in ethanol for yellow brown. The strong sulfuric acid for orange brown, diluted light orange for palm. The dye solution to join strong hydrochloric acid have orange brown precipitation; Add thick sodium hydroxide solution for red light orange brown. Apply to the cellulose fibre of printing and dyeing, also used in leather color.
