Reaction Steps

About 2 g (0.025 mol) of 1-methylimidazole and 10.7 g (0.026 mol) of 1-bromodocosane were dissolved into 20 mL of acetonitrile. The mixture was refluxed at 85° C. for 24 hours, and subsequently cooled down to room temperature. The resulting samples (cake like) were filtered and washed with ethyl ether three times. The final product: 1-docosanyl-3-methylimidazolium bromide was obtained as a white powder after being dried in a vacuum oven. The yield of this procedure was 81.4% with a melting point (Mp): 82.9° C. The spectra of 1H NMR (CDCl3 as the solvent, δ, ppm) were: 10.713 (N—CH—N, s, 1H), 7.274 (N—CH—CH, s, 1H), 7.218 (N—CH—CH, s, 1H), 4.310 (N—CH2, t, 2H), 4.130 (N—CH3, s, 3H), 1.918 (N—CH2—CH2, m, 2H), 1.248 (N—CH2—CH2—(CH2)19, m, 38H), 0.874 (CH3, t, 3H).
