p-Anisidine Chemical Properties,Usage,Production

  • Chemical Properties Anisidine exists as ortho-, meta-, and paraisomers. They have characteristic amine (fishy) odors.
  • Chemical Properties grey to brown crystalline powder, granules
  • Physical properties Yellow to light brown powder, leaflets, solid or crystals with a characteristic amine or ammonialike odor
  • Uses p-Anisidine is used mostly for producing dyes, and some smaller quantities are employed in making pharmaceuticals and liquid crystals.
  • Uses Azo dyestuffs, intermediate.
  • General Description Brown crystals or dark brown solid. Characteristic amine odor.
  • Air & Water Reactions Insoluble in water.
  • Reactivity Profile p-Anisidine may be sensitive to heat, light and moisture. Reacts with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. Incompatible with alkaline materials. Incompatible with aldehydes, ketones and nitrates.
  • Hazard Strong irritant. Toxic when absorbed through the skin. Questionable carcinogen.
  • Fire Hazard p-Anisidine is flammable.
  • Safety Profile Moderately toxic by several routes. A mild sensitizer. May cause a contact dermatitis. Mutation data reported. Questionable carcinogen. See also ANILINE. When heated to decomposition it emits toxic fumes of Nox
  • Potential Exposure Anisidines are used in the manufacture of azo dyes; pharmaceuticals; textile-processing chemicals Incompatibilities: Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine,bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some coatings and some forms of plastic and rubber.
  • Environmental Fate Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).
  • Shipping UN2431 Anisidines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials
  • Purification Methods Crystallise p-anisidine from H2O or aqueous EtOH. Dry it in a vacuum oven at 35o for 6hours and store it in a dry box. [More et al. J Am Chem Soc 108 2257 1986.] Purify it also by vacuum sublimation [Guarr et al. J Am Chem Soc 107 5104 1985]. [Beilstein 13 IV 1015.]
  • Waste Disposal Dissolve in combustible solvent (alcohols, benzene, etc.) and spray solution into furnace equipped with afterburner and scrubber, or burn spill residue on sand and soda ash absorbent in a furnace.
