English title : 2-Naphthalenesulfonic acid, 6-[[2-amino-4-[(2-hydroxyethyl) amino] phenyl] The pre] - 3-[4-[4-[[7-[[2-amino-4-[(2-hydroxyethyl ) amino] phenyl] The pre] - 1-hydroxy-3-sulfo-2-naphthalenyl] The pre] phenyl] amino] - 3-sulfophenyl] The pre] - 4-hydroxy-, trisodium salt

. direct black 32, trisodium salt

traits Description : to gray-black powder. Black water-soluble, concentrated sulfuric acid was red purple, diluted black purple precipitation; In concentrated hydrochloric acid precipitation are black; Concentrated liquid caustic soda in a dark purple precipitation.

production methods : by 4,4 '- diamino-2-diphenylamine-2-sulfo diazotization (a diazotization), and γ-acid coupling (a coincidence ), a further diazotization conjugates (diazotization II), then with 2 - (aniline) ethanol for coupling and then salting-out; filtration and drying and prepared.

purposes : the goods with cotton or rayon fabric in Qingguangkang gray to black. With silk and viscose fabric, it is desirable to acidic dye silk dyeing kits, and thus two-color effect, with dyed red nylon in gray. With polyester, acrylic in a very light gray. The materials used for a wider range of viscose fabrics, knitted fabrics, such as blankets and fabric dyeing and printing, direct Shade D slightly gray ash and yellow, have spent more direct substitute D Gray.
