Acid Green 25 Chemical Properties,Usage,Production

  • Chemical Properties dark green powder
  • Uses For nylon sutures: Fed. Regist. 42, 52395 (1977). Permitted for use in drugs and cosmetics, excluding use in eye area: ibid. 47, 49628 (1982).
  • General Description Fine black or green powder.
  • Air & Water Reactions Slightly soluble in water.
  • Reactivity Profile Acid Green 25 is incompatible with strong oxidizing agents. .
  • Fire Hazard Flash point data for Acid Green 25 are not available. Acid Green 25 is probably combustible.
  • Safety Profile Moderately toxic by ingestion. Askin and severe eye irritant.
    When heated to decomposition it emits very toxic fumesof NOx, SOx, and Na2O.
  • Purification Methods Purify it by salting out three times from an aqueous solution with sodium acetate, followed by repeated extraction with EtOH [McGrew & Schneider J Am Chem Soc 72 2547 1950]. It is a green powder that is slightly soluble in Me2CO, EtOH and pyridine. It is soluble in conc H2SO4 to give a blue solution that becomes turquoise on dilution. [Allen et al. J Org Chem 7 63 1942, Beilstein 14 H 725.]
