BRILLIANT YELLOW Usage And Synthesis
Chemical Propertiesorange to reddish-brown crystals or powder
UsesBrilliant yellow is an organic diazo dye and a ground water pollutant. Removal processes for brilliant yellow include nanofibrous membrane filtration and nanoplatelet adsorption. Dyes and metabolites.
Preparation1,2-Bis(4-amino-2-sulfophenyl)ethene? double nitriding, and phenol (2 Moore) coupled.
Properties and Applicationsbrilliant yellow. Soluble in water for golden brown, and adequate soluble in ethanol for golden brown, slightly soluble in acetone and soluble fiber element. The strong sulfuric acid to red light purple, diluted for purple, have black light purple precipitation; In nitric acid solution for dark brown (not all solution). The dye solution to join strong hydrochloric acid for dark purple, have precipitation; Add thick sodium hydroxide solution for palm light orange; Add 10% sodium hydroxide solution for big red. Used for cellulose fiber and polyamide fiber dyeing, also can be used for leather and paper color. Fountain of good dye, discharge sex is very good.
