| 摘 要： | 分别采用比重瓶、乌氏黏度计和电导率仪测定了1-丁基-3-甲基咪唑四氟硼酸盐(C4mim]BF4])+乙醇胺(MEA)和C4mim]BF4]+N,N-二甲基乙醇胺(DMEA)两种二元混合物在283.15~323.15 K时的密度、黏度和电导率。用Redlich-Kister方程关联并计算了混合体系的过量摩尔体积和黏度偏差。通过电导率的实验结果计算得到了混合体系的摩尔电导率,证明有机溶剂摩尔含量对混合体系摩尔电导率的贡献符合Walden规则。

| Abstract: | Densities,viscosities and electrical conductivities of 1-butyl-3-methylimidazolium tetrafluoroborate(C_4mim]) binary mixtures with monoethanolamine(MEA) and N,N-dimethylethanolamine(DMEA) were measured from 283.15 K to 323.15 K at atmospheric pressure using a pycnometer,a Ubbelohde viscometer and a conductivity meter,respectively.The excess molar volumes and viscosity deviations were calculated and correlated with the Redlich-Kister polynomial.The molar electrical conductivities were also calculated from t... |
