Chromate(3-), bis[3-[[4,5-dihydro-3-methyl-5-(oxo-κO)-1-phenyl-1H-pyrazol-4-yl]azo-κN1]-4-(hydroxy-κO)-5-nitrobenzenesulfonato(3-)]-, disodium hydrogen Usage And Synthesis

Preparation

3-Amino-4-hydroxy-5-nitrobenzenesulfonic acid diazo, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one coupling, and then and sulfuric acid chromium and chromium acid in aqueous solution heating, in 130 ℃ : maintain 6 hours, and make them into chromium complexation.

Properties and Applications

red light orange. Soluble in water for orange, soluble in ethanol, acetone, soluble fiber element, insoluble in other organic solvents. The strong sulfuric acid in dark green light for yellow, dilute for yellow orange after; In nitric acid solution by brown in a red light yellow; In strong hydrochloric acid for yellow solution; In 10% of sodium hydroxide solution without change. Used for wool, silk and polyamide fiber dyeing and such as direct printing.
