采用超声波辅助法合成离子液体1-丁基-3-甲基咪唑溴盐([Bmim]Br)和1-丁基-3-甲基咪唑六氟磷酸盐([Bmim]PF6)，研究了超声处理时间、超声频率和原料物质的量比对[Bmim]Br 产率的影响，以及超声处理时间、超声频率和溶剂与[Bmim]Br 的质量比对[Bmim]PF6产率的影响．结果表明：超声处理时间、超声频率、原料溴代正丁烷与 N-甲基咪唑物质的量比分别为50,min、20,Hz、1.1时，[Bmim]Br 产率可达到98.88%；在超声处理时间、超声频率、溶剂与[Bmim]Br的质量比分别为50,min、20,Hz和1.5时，[Bmim]PF6产率可达到86.54%．采用红外光谱、紫外吸收光谱和核磁共振氢谱对[Bmim]Br 进行结构表征，同时采用对比法，利用红外光谱、紫外吸收光谱对[Bmim]PF6进行表征，并分别测定了[Bmim]Br和[Bmim]PF6的含水量及其在10～30,℃下的密度和折光率与温度的关系．

Ionic liquids 1-butyl-3-methylimidazolium bromide([Bmim]Br)and 1-butyl-3-methylimidazolium hexafluoro-phosphate([Bmim]PF6)were synthesized by using ultrasonic-assisted method. The factors affecting the productivity of [Bmim]Br including reaction time,frequency,the mole ratio of reactants as well as the productivity of [Bmim]PF6,including reacting time and mass ratio of solvent to [Bmim]Br were systematically investigated. The results show that the yield of [Bmim]Br was 98.88% under the optimal synthetic conditions of reaction time of 50,min,frequency 20,Hz and mole ratio 1.1,and the yield of [Bmim]PF6,was 86.54% with reaction time of 50,min,frequency 20,Hz and mass ratio of solvent to [Bmim]Br 1.5. In addition,the structure of [Bmim]Br was characterized by infrared spectra,UV absorption spectra,and NMR spectra;[Bmim]PF6,was characterized by infrared spectra and UV absorption spectra with antithesis. The contents of water and its corresponding physicochemical properties including density and refractive index between 10,℃and 30,℃were also measured.
