| 摘 要： | 合成了溴化N-正辛基吡啶离子液体,利用红外光谱对溴化N-正辛基吡啶离子液体的结构进行了表征,由特征峰可知合成了目标产物。对溴化N-正辛基吡啶离子液体进行了在水、乙醇、乙腈中的紫外光谱定性分析,结果表明溶剂的极性和酸碱性均会引起离子液体溶液的紫外光谱发生位移,因此,在研究离子液体与其他溶剂的混合溶液的紫外光谱图时,要指明所使用的溶剂。测定了溴化N-正辛基吡啶乙醇溶液在质量摩尔浓度为0.40～2.33 mol/kg范围的电导率,溴化N-正辛基吡啶乙醇溶液的电导率随浓度的升高而增大。

| Abstract: | In this paper,a new type of ionic liquid-N-octyl pyridium bromide was synthesized.The structure of OcPyBr was characterized by infrared spectrometry and analyzed.Then,the structure of OcPyBr was characterized by ultraviolet spectrometry in water,alcohol,and acetonitrile respectively.The results show that the polarity and pH would result in the changes in UV spectrum.After measuring the conductivity at each concentration of OcPyBr between 0.40 mol/kg and 2.33 mol/kg,the conductivity-σ was made linear fit on n/m,the regression equation and correlation coefficient were acquired.It could be concluded that the conductivity of OcPyBr became higher with the concentration higher. |
