Procedure
Next, the reaction solution of triethylmethylammonium methylcarbonate was reacted with 42% aqueous solution of fluoroboric acid at room temperature to obtain a reaction solution of triethylmethylammonium tetrafluoroborate. Then, the reaction solution of triethylmethylammonium tetrafluoroborate was added to n-butanol and subjected to rectification to remove methanol, dimethyl carbonate and water to obtain a tank bottom liquid containing crude triethylmethylammonium tetrafluoroborate. Then, the crude triethylmethylammonium tetrafluoroborate was purified by crystallization using n-butanol/water mixed solvent (85/15 in weight ratio) to obtain purified triethylmethylammonium tetrafluoroborate.
