A rheological study of binary mixtures of Ionic Liquid [Me3NC2H4OH]+[Zn2Cl5]- and ethanol
Appl. Rheol. 16:6 (2006) 334-339

In this paper, by means of Advanced Rheometric Expanded System (ARES), oscillatory and steady shear behavior
of binary mixtures of a quaternary ammonium based ionic liquid
[Me3NC2H4OH]+[Zn2Cl5]- with ethanol (EtOH)
were determined at 25 C and 25-50 C, respectively. The effects of shear rate, temperature and concentration on
viscosity were elucidated sufficiently. It was found that the solutions show pseudo-plastic behavior at low shear
rate and Newtonian property at higher shear rate. The addition of EtOH caused a substantial decrease in viscosity
of the ionic liquid and the viscosity of binary mixtures could be described by an exponential equation.
Arrhenius Equation and Power Law equation were applied to describe the respective effects of temperature and
shear rate on viscosity. Activation energy derived from Arrhenius equation decreased with increasing the EtOH
fraction in the mixture.
