The density of the ionic liquid [BMim][PF 6 ] at 350 K has been obtained here as 1.3216 g cm -3 , corresponding to a molar volume of 215.0 cm 3 mol -1 , matching exactly the molar volume given by Roy and Maroncelli for the ILM2 model at 350 K. The computed density lies within 0.3% of the experimental value 1.32511 g cm -3 , which was interpolated from the density data reported by Fan et al. The self-diffusion coefficients for the cation and anion with 59×10 -12 m 2 s -1 and 47×10 -12 m 2 s -1 , respectively, given by Roy and Maroncelli, seem at first to match the data in Table V reasonably well. However, their self-diffusion coefficients were not corrected for system-size effects. By performing the correction, we obtain 64.6 × 10 -12 m 2 s -1 and 52.6 × 10 -12 m 2 s -1 , using the reported system size of 343 ion pairs while employing the reported molar volume and viscosity, which agrees very well with the experimental pulsed field gradient NMR data of 64 × 10 -12 m 2 s -1 and 51 × 10 -12 m 2 s -1 reported by Tokuda et al. . These, however, exceed our data shown in Table V by about 7%. The computed viscosity of (34.29 ± 0.87) mPa s is also significantly larger than the value reported by Roy and Maroncelli of 26 mPa s, as well as the experimental viscosity of 28.9 mPa s, which was interpolated from the viscosity data reported by Fan et al. The origin of the difference from the simulation results of Roy and Maroncelli is not clear, but it might be related to the about two orders of magnitude shorter simulation run length reported in Refs. and and might also be affected by the use of the LJ-PME method in this work.
