摘要
离子液体作为一种新型的环境友好的溶剂,已被应用到越来越多的领域.合成了同系列的3种离子液体CnpyNTf2(n=2,4,5),并对其物化性质进行了研究.使用韦氏天平测量了CnpyNTf2(n=2,4,5)及其甲醇溶液的密度.通过一系列的测量和计算,得到了不同温度、不同摩尔分数下离子液体的密度和超额摩尔体积,为离子液体的进一步应用研究,提供了基础数据支持.
As a new environmentally friendly solvent,ionic liquids have been applied to more and more fields.The lack of physical and chemical properties data for ionic liquids has become a bottleneck which restricts their development.In this study deals with the investigation of ionic liquids CnpyNTf2（n=2,4,5）,the density for Binary Mixtures of CnpyNTf2（n=2,4,5） and the methanol measured using Westphal balance.A series of density and excess molar volume data for different temperature and mole fraction are obtained by measurement and calculation.It provides basic data for the application of ionic liquids.
