Thermophysical properties of 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide at high temperatures and pressures

Thermodynamic Properties at Saturation Derived from Experimental Two-Phase Isochoric Heat Capacity of 1-Hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide

“…Good agreement within 0.07 % to 0.10 % was observed between the present and the reported density data by Kato and Gmehling [16], Azevedo et al [17], Jacquemin et al [22], Kandil and Marsh [23], and Ahosseini et al [24]. Acceptable agreement within 0.14 %, 0.15 %, 0.17 %, and 0.17 % was found between the present and the data of Iguchi et al [25], Mohammad et al [18], Widegren and Magee [20], and Safarov et al [13], respectively. The relative large discrepancy within 0.30 %, 0.27 %, and 0.22 % is observed between the data reported by Esperança et al [19], Tariq et al [6], and Gonzalez et al [15] and the present saturated density data, respectively.…”

“…The relative large discrepancy within 0.30 %, 0.27 %, and 0.22 % is observed between the data reported by Esperança et al [19], Tariq et al [6], and Gonzalez et al [15] and the present saturated density data, respectively. Our previous saturated density measurements [27] at high temperatures deviate from the Tariq et al [6] and Safarov et al [13] reported data within 0.35 %. The deviations within 0.34 % was also observed between our previous studies [27] and the data reported recently by Iguchi et al [25].…”

“…2 in a projection of T S - ρ S data. This figure also depicts the values of density as a function of temperature at atmospheric pressure ρ ( T ) calculated from reference correlation [1] at atmospheric pressure and other reported density data [6,13,15–25,27] at atmospheric pressure published after IUPAC project reports [1,2] (after 2009). Table 3 presents the deviations (absolute average deviation, AAD) between the present saturated density data and reported densities at atmospheric pressure (second column).…”

Dashed line is calculated from reference correlation by Chirico et al [1] (extrapolation to higher temperatures, out of validity of the correlation); (–·–·–·–), Safarov et al [13]. Solid line is calculated from correlation by Bochmann and Hefter [5]…”

Thermophysical Properties of 1-Butyl-3-Methylimidazolium Bis(trifluoromethylsulfonyl)imide at High Temperatures and Pressures

“…This work is a continuation of our investigations in the field of thermophysical properties of ionic liquids (Safarov et al, 2013). The first density data of [BMIM][NTf 2 ] were measured at T = 298.15 K by a simple gravimetric analysis using 1 mL by pipette and the average density data was reported by Huddleston et al (2001).…”
