실험 절차

450 g of 1-bromopropane (3.66 mol) are loaded into a 1 l glass reactor. The mixture is heated to 70° C. and then 200 g of 1-methylimidazole (2.44 mol) are poured in dropwise, with stirring. The mixture is left to react for 1 h at 70° C. After returning to room temperature, the mixture is separated by decantation. The bottom ionic liquid phase is recovered, washed with toluene (1×100 ml), and then evaporated under vacuum. 475 g of 1-methyl-3-propylimidazolium bromide are obtained in the form of a yellow liquid. The product is used as a base without further purification.
