実験手順

1 mole of 1-methylimidazole was dissolved in 400 ml of ethanol and 1.2 moles of n-octyl bromide were added. The mixture was then heated to the boiling point for 5 hours. Thereafter, ethanol and excess n-octyl bromide were removed. The residue was purified in ether. In this manner, 250 g of 1-n-octyl-3-methyl-imidazolium bromide were obtained.
