Air-and water-stable hydrophobic ionic liquids N-alkylpyridinium bis(trifluoromethylsulfonyl)imide ([C n py][NTf 2 ], n = 3, 6) were synthesized. The density, surface tension, dynamic viscosity, and electrical conductivity of [C 6 À ILs as a hydrophobic compound has attracted much more attention in some fields. 5À8Tokuda et al. 9 have studied the properties of a series of imidazolium-based ILs, for example, the melting temperature, glass transition temperature, dynamic viscosity, and electrical conductivity. The melting temperatures are lower than room temperature, so these ILs are liquid at room temperature; the decomposition temperatures are higher than 690 K, so these ILs exhibit excellent thermal stability. The electrical conductivities are also high enough to be applied in electrochemical devices. Oliveira et al.10 studied the properties of a series of pyridiniumbased ILs. The density and dynamic viscosity of the dried and saturated ILs were studied. The water content has a strong effect on the dynamic viscosity, but only a very small effect on density was observed. Jacquemin et al.11 have also studied the density and dynamic viscosity of several pure and watersaturated ILs. The same results were obtained for the effect of water content on the density and dynamic viscosity. The ILs with [NTf 2 ] À anion were studied widely because this type of ILs has a relatively low viscosity, a wide electrochemical window, and a high electrical conductivity to be applied in the electrochemical devices. 12À16In view of the above facts, the density, surface tension, dynamic viscosity, and electrical conductivity of the ILs [C n py][NTf 2 ] (n = 3, 6) were measured at different temperatures, except for the surface tension of [C 3 py][NTf 2 ]. The speed of sound was estimated by the Auerbach relation at the different temperatures. 17The standard molar entropy and lattice energy were estimated in terms of Glasser's theory. 18 Parachor was estimated by the equation reported in the ref 19. The molar enthalpy of vaporization was estimated in terms of Kabo's empirical equation. 20 The interstice volume, interstice fraction, and thermal expansion coefficient were estimated by the interstice model theory. 21,22 The VogelÀFulcherÀTammann (VFT) and Arrhenius equations were used to fit the temperature dependence on dynamic viscosity and electrical conductivity values.' EXPERIMENTAL SECTION Preparation of ILs [C n py][NTf 2 ] (n = 3, 6). N-Alkylpyridinium bromide ([C n py][Br], n = 3, 6) was synthesized according to the procedure described in earlier paper. 23 [C n py][NTf 2 ], n = 3, 6, were synthesized according to the ion exchange reaction. The 80 g of salt [C n py][Br], n = 3, 6 was placed in a 500 mL roundbottomed flask and dissolved in 30 mL of distilled water; the equivalent amount of bis(trifluoromethanesulfonyl)imide (HN-(SO 2 CF 3 ) (Rhodia Co., mass purity 99.9 %) was added dropwise

Abstract:The potential of 1-butyl-3-methylimidazolium tetrachloroferrate ([bmim] O was reduced to FeCl 2 , at the same time, H 2 S was oxidized to S 8 . In addition, the decrease in acidity caused by increasing the water content increased the weight percent of absorbed H 2 S, and decreased volatile HCl emissions. However, it is difficult to prevent the suspended S 8 generated at vol % (H 2 O) ≥ 80% from the formation of sulfur blockage. Therefore, oxidative absorption of H 2 S by [bmim]Fe(III)Cl 4 -H 2 O mixtures is feasible at vol % (H 2 O) < 80% without sulfur blockage.

“…8 The model was built on the basis of the following assumptions: 1. due to the large size and the asymmetric shape, the ions may not be closely packed and lots of interstices between ions come into existence; 2. in order to calculate the volume easily, the interstice is regarded as a bubble; 3. there are 2N interstices for 1 molar 1-1 ionic liquid, where N is Avogadro number; 4. the interstice in BMIGaCl 4 can move about like an ion or other particles, and in the movement the interstice does not vanish, but can be compressed or expanded, which has an extra feature of motion of an interstice called the breathing motion.…”

“…There is limited number of reports of ionic liquids based on metals other than aluminum. [7][8][9] To develop RTIL chemistry of the third main group, we report that such an ionic liquid has been prepared by directly mixing GaCl 3 and 1-methyl-3-butylimidazolium chloride with molar ratio of 1/1 under argon atmosphere. We determined the densities and surface tension of the BMIGaCl 4 in a temperature range of 268.15 to (338.15± 0.1) K. The expression of average volume of the interstices, ν, was derived on the basis of the interstice model.…”

An ionic liquid (IL) BMIGaCl 4 was prepared by directly mixing GaCl 3 and 1-methyl-3-butylimidazolium chloride with molar ratio of 1/1 under argon atmosphere. The densities and surface tensions of this pure ionic liquid were determined in the temperature range of 268.15 to (338.15±0.1) K. A new theoretical model of ionic liquids, an interstice model, was applied to calculate the thermal expansion coefficient of IL BMIGaCl 4 , α, and the magnitude order of its value calculated by the theory was the same as experimental one. Both Raman scattering and ab initio calculations indicate that 4 GaCl-is the only species containing Ga in the ionic liquid BMIGaCl 4 .
