通过一步法合成了基于1,3-二烷基咪唑阳离子和甲烷磺酸或对甲苯磺酸阴离子的无卤素离子液体,并对它们的物理化学性质如聚集行为、表面性质、热性质、密度、黏度、折光率和电化学性质等进行了详细研究.结果表明在甲烷磺酸阴离子基离子液体中观察到离子液体中普遍存在的离子簇行为;同等条件下[BEim]MS的荧光光谱强度较[BEim]TS弱;[C12Mim]MS展现出液晶行为;[TS]-基离子液体有着较高的折光率,大于1.51.
Halogen-free ionic liquids based on 1,3-dialkylimidazolium cation and methanesulfonic acid or p-toluenesulfonic acid anion were synthesized by one-step method and their physicochemical properties such as aggregation behavior, surface properties, thermal properties, density, Viscosity, refractive index and electrochemical properties were studied in detail.The results show that the ion cluster behaves ubiquitously in the ionic liquid of methanesulfonic acid, and the fluorescence intensity of [BEim] MS under the same conditions is better than [ BEim] TS is weak; [C12Mim] MS exhibits liquid crystal behavior; [TS] - the base liquid has a higher refractive index, greater than 1.51.
