DENSITY, VISCOSITY AND THERMAL CONDUCTIVITY OF HMIMBF4 AND OMIMBF4 AT HIGH PRESSURE
Density, viscosity and thermal conductivity are reported for a series of 1-alkyl-3-methylimidazolium tetrafluoroborate having hexyl, and octyl groups, which are expressed by HMIMBF4, OMIMBF4, respectively. The density was measured with a vibrating tube densimeter. The viscosity was measured with a rolling ball viscometer. The experimental temperatures were from (293.15 to 353.15) K and pressures were up to 20.0 MPa. The experimental method used for thermal conductivity was a transient short hot wire method. Since only a small amount of sample liquid is required, this method was found to be effective for the thermal conductivity measurements of ionic liquids (ILs). The experimental temperatures ranged from 294 to 335 K at pressures up to 20 MPa. It was found that an effect of the length of the alkyl chain on the thermal conductivities in ILs is relatively small.
