| Hazard Information | Back Directory | [Chemical Properties]
Bright yellow powder. Soluble in water, the aqueous solution turns lemon yellow. Addition of concentrated hydrochloric acid or concentrated sodium hydroxide to the aqueous solution does not change color. Dissolved in ethanol, it turns lemon yellow and is slightly soluble in acetone. It turns lemon yellow in concentrated sulfuric acid and retains color after dilution. When dyed, the color becomes slightly darker red when exposed to copper ions, darker green when exposed to iron ions, and remains unchanged when exposed to chromium ions. | [Uses]
C.I. Acid yellow 42 is an acidic yellow dye that can be adsorbed and removed by bentone. | [Preparation]
2,2′-Disulfo-4,4,diaminobibenzene double nitriding, and 3-Methyl-1-phenyl-1H-pyrazol-5(4H)-one? (2 Moore) coupled. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
yellow to red light yellow. Bright yellow powder. A lemon yellow soluble in water, soluble in ethanol is lemon yellow, slightly soluble in acetone. Meet strong sulfuric acid is lemon yellow, dilute still is shown after lemon yellow. Its water solution meet strong hydrochloric acid is lemon yellow; Sodium hydroxide solution meet strong a lemon yellow. In dyeing of copper (a little red dark, encounter chromium ion unchanged, encounter iron ion turn green dark. Mainly used for wool dyeing and can be used for wool, silk and glue directly printing, has the good discharge sex, can be used for the polyamide fiber dyeing and leather shading.
