摘要
为了研究原料、温度和反应时间对离子液体的产率的影响,以及离子液体在不同溶剂中的溶解性能,以1-乙烯基咪唑为原料,合成了1-乙烯基-3-氨丙基咪唑盐离子液体,利用1HNMR对合成产物进行性能表征。实验结果表明:以溴代烷烃为原料,控制温度80℃,反应24h,能够得到产率为91%的产物;且合成的离子液体极性较大,只能溶解于极性较大的溶剂中。
In order to study the effect of yield of raw materials,reaction temperature and time on the ionic liquid,and the solubility properties of ionic liquids in different solvents,the paper was used 1-vinyl imidazole to synthesis1-vinyl- 3-aminopropyl imidazolium ionic liquid,and researched performance characterization of the synthetic product by1 HNMR. The experimental results was showed that： if it＇s used hydrocarbon bromide as raw material,the temperature is 80℃,reaction time is 24 h,the yield can reach 91%; the product can only be dissolved in the larger polar solvents due to more polar.
