使用微波法制备亲水性咪唑类离子液体[RMIm]Br,并进行了核磁共振(NMR)和红外光谱(IR)的表征.考察了在模型油品脱硫中剂油比、温度、萃取级数、离子液体种类等因素对脱硫率的影响,重点测试了离子液体在含水量不同情况下脱硫效果及其吸湿率,并提出了水萃取再生的方法.从大量数据说明亲水性咪唑类离子液体[RMIm]Br具有较好的脱硫效果,且在较长的时间里其吸湿性对脱硫影响不大,故在工业上有较好的应用前景.

Hydrophilic imidazolium-based ionic liquids [RMIm]Br were prepared by microwaved method and tested in model oil desulfurization, they were characterized by nuclear magnetic resonance (NMR) infrared spectrum(IR). The desulfurization influencing factors including ratio of solvent to oil , temperature, extractive times, type of ionic liquids and especially the water content in [RMIm]Br were investigated. Regeneration method by water extraction was proposed after the water absorption experiments being conducted. A lot of experiment data show hydrophilic imidazolium-based ionic liquids [RMIm]Br have good EDS performance and the hydroscopicity has little effect on EDS.
