Procedure

251.4 g of 1-chlorobutane (2.7 mol) are loaded into a 1 l glass reactor. The mixture is heated to 60° C., and then 148.6 g of 1-methylimidazole (1.8 mol) are poured in dropwise, with stirring. The mixture is left to react for 24 h at 80° C. The reaction mixture is evaporated under vacuum. 309 g of 1-butyl-3-methylimidazolium chloride are obtained in the form of a yellowish solid (yield=98%). The product is used as it is without further purification.
