2-Chloroaniline Chemical Properties,Usage,Production

  • Chemical Properties clear pale yellow to brown liquid
  • Uses Dye intermediate, standards for colorimetric apparatus, manufacture of petroleum solvents and fungicides.
  • Synthesis Reference(s) The Journal of Organic Chemistry, 39, p. 2718, 1974 DOI: 10.1021/jo00932a011
    Tetrahedron Letters, 26, p. 3277, 1985 DOI: 10.1016/S0040-4039(00)98171-1
  • General Description Clear amber liquid with an amine odor. Occurs in both alpha and beta forms.
  • Air & Water Reactions Sensitive to prolonged exposure to air and darkens on exposure to light. Insoluble in water.
  • Reactivity Profile 2-Chloroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents.
  • Hazard Toxic by ingestion.
  • Fire Hazard 2-Chloroaniline is combustible.
  • Safety Profile Poison by skin contact, ingestion, and subcutaneous routes. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl and NOx. See also ANILINE DYES.
  • Purification Methods Free it from small amounts of the p-isomer by dissolving in one equivalent of H2SO4 and steam distilling. The p-isomer remains behind as the sulfate. [Sidgwick & Rubie J Chem Soc 1013 1921.] An alternative method is to dissolve it in warm 10% HCl (11mL/g of amine) and on cooling, o-chloroaniline hydrochloride separates out. The latter can be recrystallised until the acetyl derivative has a constant melting point (m 90o). (In this way, yields are better than via the recrystallisation of the picrate from EtOH or of the acetyl derivative from pet ether.) [King & Orton J Chem Soc 1377 1911]. [Beilstein 12 III 1281, 12 IV 1115.]
