Abstract

This work conducts the first study on the effect of compressed CO₂ on the electric conductivity of ionic liquids (ILs), and the CO₂/1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF₆]) system is investigated at 40.0 °C and 50.0 °C, and at pressures up to 130 bar. It is found that the conductivity increases with increasing pressure of CO₂ in the pressure range studied, although CO₂ is a non-polar compound.
