摘要
以哌啶、溴代正丁烷和烯丙基溴为原料,采用两步法合成出了烯丙基哌啶类离子液体,并用红外光谱(IR)对产物进行了分析表征。同时考察了其在不同溶剂中的溶解性能及导电性能。结果表明,离子液体在水、乙醇、乙酸、丙酮中可以较好的溶解,而在乙醚、正己烷中基本不溶;离子液体的电导率随浓度的增大和温度的升高而增大。
Allylic piperidine ionic liquid was synthesized using piperidine, n-bromic butane, allylic bromine as raw materials by two-step method, the product was characterized by infrared spectrum（IR）. In the meantime, the solubility and electrical conductivity of the ionic liquid were measured. The results show that ionic liquid can dissolve better in water, ethanol, acetic acid and acetone, but not dissolve basically in ethyl ether and hexane. The electrical conductivity of the ionic liquid increases with the increase of the concentration and temperature.
