synthetische
: in reflux conditions, sodium hydroxide solution in (E)-2-(2-sulfo-4-nitrostyryl)-5-nitrobenzenesulfonic acid with 5-Amino-2-methoxybenzenesulfottic aciddiazotization and 2,5-Dimethylbenzenaminecoupled with product heating (molecular ratio is about 1 to 1), then use glucose and sodium hydroxide deal with the product.
Properties and Applications
red light orange. Soluble in water for palm light orange, soluble in ethanol for light golden brown. In the strong sulfuric acid as dark blue, diluted for olive to olive brown, black precipitation. The dye solution to join strong hydrochloric acid for yellow olive brown, have precipitation; Add thick sodium hydroxide solution have red light orange brown precipitation. Used for the cellulose fibre, silk dyeing, can be used for leather and paper shading, Exhaust dyeing. In dyeing copper and iron ion reddish light, a little sensitive fights.
