中文摘要：

受亲水有机胺与CO2进行化学反应的启发,将胺功能基团能引入到咪唑环上,合成含胺功能基团的离子液体。本研究以四个亚甲基为连接基,合成含胺功能基团的Gemini咪唑离子液体1,4-二（溴化3-乙胺基咪唑）丁烷,所合成的物质经红外、核磁共振氢谱表征确为目标产物。进行了简单的吸收实验,其对CO2的吸收比物理吸收高很多,可与CO2按照1∶1的化学计量比进行化学反应。

英文摘要：

Taking a cue from the chemistry of aqueous organic amines reacting with CO2,amine functionalities can be added to ionic liquids to introduce specific and tunable chemical reactivity with CO2.The Gemini amine functional ionic liquid 1,4-bis（3-aminoethyl imidazolium-1-yl） butane bromide was synthesized with four methylene as spacer.The products were characterized by the way of FT-IR and 1H NMR.The results proved that they were all the objective products.Experimental of absorption result indicated that while CO2 uptake of ILs with Gemini amine-functionalized cations is much greater than is possible by physical absorption.The Gemini amine functional ionic liquid can react with CO2 on 1∶1 reaction stoichiometry.
