Reaction Conditions

Reaction Steps

1-bromobutane (110 mmol, 15.07 grams) and 1-methylimidazole (100 mmol, 8.21 grams) were added to a 250 mL flask. The reaction mixture was stirred for 48 hours at 80° C. The resulting ionic liquid was then cooled, washed with ether (3×25 mL) to remove unreacted starting materials, and the product was dried under vacuum at 80° C. for 4 hours to afford 1-butyl-3-methylimidazolium bromide [BMIMBr] in a yield of 93% with 96% purity. The procedure was repeated using 1-chlorobutane and 1-iodobutane to give the corresponding chloride and iodide salts.
