“…Excellent agreement was found between density data of each pure component measured herein with those available in the literature: that is, <0.1% average deviation between experimental and literature values for [Pyrr 14 ][TFSI] − and ADN ,− and ca. 0.2% deviation for GLN − , and BTN. − The percentage deviations between experimental density values reported in this work for the neat components and those reported previously in the literature are shown in Figures S7 to S10. Furthermore, and as expected, all of the mixtures and single components exhibited a typical linear decrease as a function of increasing temperature.…”

“…The viscosity of the pure IL (77.7 mPa·s at 298.15 K) has been measured many times previously, and the values reported here are in good agreement with values in the literature (ca. 0.2–2% deviation between experimental and literature values). ,,,,− The viscosity data of the pure dinitrile solvents, although less readily found in the literature, are considered in reasonable agreement with the available data, GLN ,, and ADN. ,,,, However, the measured viscosity of the pure BTN (0.8 mPa·s at 298.15 K) appears to be overestimated across the full temperature range when compared to reference values (0.55 mPa·s at 298.15 K). ,, While the absolute difference is small (ca. 0.25 mPa·s), the relative difference is over 30% at 298 K and most significant for the neat mononitrile solvent.…”

In the scope of improving the energy and power densities of electrochemical double layer capacitors (EDLCs), the development of high performance electrolytes with enhanced operative voltages is imperative. The formulation of mixtures containing ionic liquids with organic molecular solvents is an important strategy in the pursuit of developing highly electrochemically stable and safe materials while retaining fast transport properties for high power applications. In this work, we report on the physical–chemical investigations into binary mixtures containing the ionic liquid 1-butyl-1-methylpyrrolidinium bis{(trifluoromethyl)sulfonyl}imide with one mononitrile solvent, butyronitrile, and two dinitrile solvents, glutaronitrile and adiponitrile, as potential electrolytes for EDLCs. The thermal, volumetric, and transport properties of the binary mixtures are investigated as functions of the electrolyte composition and temperature. Furthermore, the electrolyte composition which exhibits the highest conductivity for each of the binary mixtures was determined, and its electrochemical stability is reported using a glassy carbon macrodisk electrode.

The isobaric vapor–liquid equilibrium (VLE) data for the binary system of adiponitrile + cyclopentanone at 5 and 10 kPa were determined with a modified Rose–Williams still. The reliability of the apparatus was verified by the measurements of the vapor pressure of cyclopentanone and water at varying temperatures. The thermodynamic consistency of VLE data was tested by methods suggested by Wisniak and Van Ness. Five activity coefficient models, including van Laar, Margules, Wilson, NRTL, and UNIQUAC models, were used to correlate the VLE data, and the excess Gibbs free energy of the binary system was determined. The parameters of the five activity coefficient models were obtained using the experimental data, and the regression results were evaluated by RMST (defined by eq 12) and RMSy 1 (defined by eq 13). The results show that the deviation of temperature calculated by the Margules model is larger than those calculated by other models, and the Wilson, NRTL, and UNIQUAC models are all acceptable for this system. Furthermore, the UNIQUAC model shows the best prediction accuracy among these models with RMST and RMSy 1 less than 1.2 and 0.007, respectively.
