Procedure

To a 200 ml four necked flask equipped with a stirrer, a dropping funnel, a cooling tube and a thermometer, 32.84 g (0.4 mol) of 1-methyl imidazole and 40 ml of toluene were charged and heated at 50° C., to which 68.63 g (0.44 mol) of ethyl iodide was dropped slowly taking one hour. After dropping and further reacting at 50° C. for 4 hours, precipitates were separated by filtration, subjected to solvent cleaning and dried under a reduced pressure to obtain 90.47 g of 1-ethyl-3-methyl imidazolium iodide salt.
