formula : C45H25N10Na6O21S6
molecular weight : 1251.98
Chinese name : direct red dyes; Then Buried red Light F3B

English title : C.I.Direct Red 80 (35,780); Amanil Fast Red 8BLN; Red Light Diazol 3B; Duaazol Red B; Sirius Red dyes; Solar Brilliant Red BA; Solophenyl Red 3BL; Sumilight Red F3B

traits Description : powder on, the water-soluble red to blue was red goods, ethanol and insoluble fiber-dissolved, he has not dissolved organic solvents. The concentrated sulfuric acid was blue, was diluted to purple red and blue; The concentrated nitric acid were blue; Its case of concentrated hydrochloric acid solution emerging purple precipitation; Encountered thick liquid caustic soda was red purple. With cotton fiber has to do with good, the pair of 100 ° C fibers with the greatest affinity.

production methods : acid 1.J by diazotization of sulfanilic acid, and amino acid coupling neighbors, and the second meeting of the drought diazotization and then with N-acetyl-butanoic acid (N acid-2-amino-5-naphthol-7-sulfonic acid), for the second coupling, and through the hydrolysis of acetyl-off final with phosgene condensation, and salting-out, ie the goods. 2. Scarlet acid by diazotization of sulfanilic acid, and amino acid coupling neighbors, and for the second time diazotization and then with the Scarlet acid [ie N, N-bis (5-hydroxy-7-sulfonic acid-2-naphthyl) urea] coupling, in which Salt the Commodities.

purposes : mainly for cotton, rayon, silk and wool and fabric dyeing, printing (with silk and wool dyeing cotton than Color Yield slightly shallow). Can also be used for leather and paper coloring. Right acetate fibers and nylon without staining.
