synthetische
1-Methyl-2,4-dinitrobenzene?and Sodium polysulfide in 220 ~ 230 ℃ calcination 15 ~ 20 hours, with Sodium hydroxide product processing.
Properties and Applications
brown. Brown powder. In the water partly dissolved, for brown. In the Sodium sulfide solution solubility is good, for yellow to red orange; In concentrated sulfuric acid partly dissolved, for orange brown, dilution have orange brown precipitation. In acetic acid or metal chromium, copper red, dark. In the basic insurance powder solution is almost invariant color; In Sodium hypochlorite solution for light yellow, join concentrated sulfuric acid turn yellow. Used for cotton, hemp, and viscose fabric dyeing.
