| Abstract: | The influence of temperature on viscosity and specific conductivity of Bmim] FeCl4 ionic liquid was investigated in relation to comparison with literature data. Results show that the viscosity of Bmim] FeCl4 can be accurately measured with both rotational rheometer and falling sphere viscometer. In contrast with Andrade equation, VTF equation can better fit the viscosity of -Bmim] FeCl4 ionic liquid versus temperature, with the correlation coefficient being 0. 999 9. Besides, the specific conductivity of Bmim] FeCl4, determined with different electric conductivity analyzers, shows much difference; and the conductivity versus temperature can be better fitted using VTF equation rather than Arrhenius equation. Moreover, with rising temperature, the specific conductivity versus viscosity of -Bmim] FeCl4 ionic liquid conforms to Walden plots, with the correlation coefficient being over 0.99. |
