Acid Yellow 42 Chemical Properties,Usage,Production

  • 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 Not classified
  • 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.
