Versuchsvorschrift

1-Methylimidazole (8.2 g, made by Aldrich) and propyl iodide (16.9 g, made by Kanto Chemical) were stirred in toluene at 75° C. for 15 hours. After the end of the reaction, the reaction solution separated into the two layers of a toluene layer and an ionic liquid layer. By removing the toluene layer from the reaction solution, the ionic liquid was obtained. The ionic liquid obtained was washed with toluene 3 times for purification. The toluene was distilled off in vacuo, whereby an ionic liquid 1-methyl-3-propylimidazolium iodide (23.8 g) was obtained.
