| Zusammenfassung: | The invention discloses a synthetic method of tetrafluoroborate ionic liquid. The method comprises the following steps: enabling a quaternized substrate and alkyl halide to be dispersed in a solvent in a molar ratio of 1 to (1-7), adopting ultraviolet irradiation at 30-50 DEG C, enabling illumination intensity to be 10-1,000W/m and irradiating for 8-12h to obtain a quaternary ammonium salt solution; enabling the quaternary ammonium salt solution and tetrafluoroborate to be uniformly mixed, adopting the ultraviolet irradiation at 35-45 DEG C, enabling the illumination intensity to be 10-1,000W/m and irradiating for 16-20h to obtain mixed liquor; enabling the mixed liquor to be filtered to obtain filtrate, enabling the filtrate to be heated and concentrated, and removing the solvent toobtain the tetrafluoroborate ionic liquid. The method adopts the modes of ultraviolet irradiation and heating to synthesize the tetrafluoroborate ionic liquid, and the yield and reaction rate are high.
