ACID ORANGE 51 Chemical Properties,Usage,Production

  • Uses Acid orange 51 is an azo dye.
  • Preparation 2-(4-Aminophenylamino)-5-nitrobenzenesulfonic acid diazotization and 5-Aminonaphthalene-2-sulfonic acid and 8-Aminonaphthalene-2-sulfonic acid coupling, and its product and diazotization, coupling with o-Cresol, 4-Methylbenzene-1-sulfonyl chloride?and then esterified
  • Properties and Applications red light orange. Dark red light orange powder. Soluble in water, ethanol, glycol ether. The strong sulfuric acid dyes for deep blue light green, dilute precipitation after brown; In nitric acid solution for olive, then into amber color. Its water solution for brown, add after strong hydrochloric acid for blu-ray black, with precipitation; Add thick sodium hydroxide solution colour and lustre is unchanged. This product used for wool, silk, polyamide fiber dyeing, also used in wool blended fabric or viscose fabric printing directly. Can also be used in leather, soap color. Dyed hair and scattered over the tops of often used alone.
