抜粋

Viscosity and thermal conductivity values are reported for a series of 1-alkyl-3-methylimidazolium tetrafluoroborate compounds with hexyl (1-hexyl-3-methylimidazolium tetrafluoroborate) and octyl (1-octyl-3- methylimidazolium tetra-fluoroborate) groups. The viscosity was measured with a rolling-ball viscometer at 293.15K to 353.15 K and pressures up to 20.0 MPa. The experimental values were correlated with a hybrid VFT-Tait equation. The thermal conductivity was measured using the transient short hot-wire method at 294K to 335 K and pressures up to 20.0 MPa. The experimental values at 293.15K and 0.1 MPa agreed with the predicted values proposed by Fröba et al.
