Thermal Conductivities of Imidazolium-Based Ionic Liquid + CO2 Mixtures

Experimental results for the thermal conductivities of imidazolium-based ionic liquid + CO 2 mixtures are reported. The thermal conductivities were measured with a transient short-hot-wire method. The experimental temperatures were from 294 K to 334 K, and pressures were 10.0 MPa and 20.0 MPa. The CO 2 mole fractions of the mixtures covered a range up to 0.42. It was found that the thermal conductivities of ionic liquids have a very small CO 2 mole fraction dependence.
