ABSTRACT
Experimental results for the thermal conductivities of imidazolium-based ionic liquid+CO2 mixtures are reported. The thermal conductivities were measured with a transient short-hot-wire method. The experimental temperatures were from 294K to 334 K, and pressures were 10.0MPa and 20.0MPa. The CO2 mole fractions of themixtures covered a range up to 0.42. It was found that the thermal conductivities of ionic liquids have a very small CO2 mole fraction dependence.
