Procedure

22.3 ml of N-methylimidazole and 120 ml of 1,2-dichloroethane were introduced into a 250 ml glass flask under an argon atmosphere. 53.2 g of triethyloxonium tetrafluoroborate was added in small portions. The reaction medium was observed to heat up slightly and the solvent was then refluxed for 1 hour 30 minutes. The molten salt formed was colorless, non miscible and denser than the 1,2-dichloroethane. It was separated by simple decanting and drawn under vacuum using a vane pump.
