(2) mixing the quaternary ammonium salt solution obtained in the step (1) with sodium tetrafluoroborate (the molar ratio of 1-methylimidazole to sodium tetrafluoroborate is 1:1), After heating to 40 ° C, Under agitation, Irradiation with ultraviolet light of 600 W/m2, The exposure time is 18h, a mixed solution containing a tetrafluoroborate ionic liquid; (3) filtering the mixture obtained in the step (2) twice, Get the filtrate, The filtrate was concentrated at 60 ° C. Remove ethanol, Obtaining 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid, The yield was 94%. See Table 1 for the properties of the resulting ionic liquid.
