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. | [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.] |
