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。
Densities, viscosities and electrical conductivities of 1-butyl-3-methylimidazolium tetrafluoroborate ([C4mim][BF4 ]) 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 the experimental values and the effects of the concentration of solvents on the molar electrical conductivities are in accord with the Walden rule.
