Direct green 34 (C.I. 27970) Usage And Synthesis
Preparation2-(2-Sulfo-4-nitrostyryl)-5-aminobenzenesulfonic acid diazo, and 4-Hydroxynaphthalene-1-sulfonic acid coupling, and then in the presence of copper sulfate its into three thiazole structure of compounds, and the method will be reduced to amino Nitro. The product diazo, and 5-Amino-7-ehtoxy-2-naphthalenesulfonic acid coupling, again diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling.
Properties and Applicationsgreen. Soluble in water for SAP green, slightly soluble in ethanol is shallow olive gray. The strong sulfuric acid for blue-ray gray, diluted green for blue-ray. The dye solution with strong hydrochloric acid with olives to blue light grey precipitation; Add thick dark blue light green sodium hydroxide solution precipitation.
