1-Bromo-2-methylpropane Chemical Properties,Usage,Production

  • Chemical Properties CLEAR LIQUID
  • Uses 1-Bromo-2-methylpropane is used as a synthetic reagent for the preparation of 1-ethyl-1,3-isobutylimidazolium bromide by reaction with 1-ethylimidazole.
  • Safety Profile Questionable carcinogen with experimental neoplastigenic data. Moderately toxic by intraperitoneal route. A dangerous fire hazard when exposed to heat or flame. When heated to decomposition it emits toxic fumes of Br-. See also BROMIDES.
  • Purification Methods Partially hydrolyse it to remove any tertiary alkyl halide, then fractionally distil it, then wash it with conc H2SO4, water and aqueous K2CO3, then redistil it from dry K2CO3. [Dunbar & Hammett J Am Chem Soc 72 109 1950, Beilstein 1 IV 294.]
