A novel approach for the halide-free, continuous-flow preparation of hydrophobic ionic liquids (ILs) relying on the bis(trifluoromethanesulfonyl)imide (bistriflimide, NTf₂^–) anion. The simple yet fast two-step synthetic route, which involved the formation of different alkyl bistriflimides (RNTf₂), followed by the quaternization with an amine nucleophile, led to the desired ILs in high yields and excellent purities without any byproduct formation. The variable alkyl chain (R) length and the broad range of the applicable nucleophiles offer considerable flexibility to the synthetic protocol. The quaternization could be performed under solvent-free conditions; moreover, the homogeneous nature of these reactions allowed the application of modern continuous-flow technologies. Given these advantages, the methodol. could afford not just a fast and efficient alternative for the conventional synthesis of such compounds with reduced waste water production but their negligible halide content might provided a significantly broader application range of the IL products, especially for the field of materials science.

Effects of self-hydrogen bonding among formamide molecules on the UCST-type liquid-liquid phase separation of binary solutions with imidazolium-based ionic liquid, [C_nmim][TFSI], studied by NMR, IR, MD simulations, and SANS was written by Kawano, Masahiro;Tashiro, Atsuya;Imamura, Yuki;Yamada, Moeno;Sadakane, Koichiro;Iwase, Hiroki;Matsugami, Masaru;Marekha, Bogdan A.;Idrissi, Abdenacer;Takamuku, Toshiyuki. And the article was included in Physical Chemistry Chemical Physics in 2022.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The upper critical solution temperature (UCST)-type liquid-liquid phase separation of imidazolium-based ionic liquids (ILs), 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C_nmim][TFSI], where n represents the alkyl chain length of the cation, n = 6, 8, 10, and 12) binary solutions with formamide (FA) was examined as a function of temperature and the FA mole fraction x_FA. The two-phase region (immiscible region) of the solutions is much larger and expands more with the increase in n, in comparison with the previous [C_nmim][TFSI]-1,4-dioxane (1,4-DIO) systems. An array of spectroscopic techniques, including ¹H and ¹³C NMR and IR combined with mol. dynamics (MD) simulations, was conducted on the present binary systems to clarify the microscopic interactions that contribute to the phase-separation mechanism. The hydrogen-bonding interactions of the imidazolium ring H atoms are more favorable with the O atoms of the FA mols. than with 1,4-DIO mols., whereas the latter interact more favorably with the alkyl chain of the cation. Upon lowering the temperature, the FA mols. gradually self-aggregate through self-hydrogen bonding to form FA clusters. Concomitantly, clusters of ILs are formed via the electrostatic interaction between the counter ions and the dispersion force among the IL alkyl chains. Small-angle neutron scattering (SANS) experiments on the [C₆mim][TFSI]-FA-d₂ and [C₈mim][TFSI]-FA-d₂ systems revealed, similarly to [C_nmim][TFSI]-1,4-DIO systems, the crossover of the mechanism from the 3D-Ising mechanism around the UCST x_FA to the mean-field mechanism at both sides of the mole fraction. Interestingly, the x_FA range of the 3D-Ising mechanism for the FA systems is wider compared with the range of the 1,4-DIO systems. In this way, the self-hydrogen bonding among FA mols. most significantly governs the phase equilibrium of the [C_nmim][TFSI]-FA systems.

Quantitative Analysis of Conductivity and Viscosity of Ionic Liquids in Terms of Their Relaxation Times was written by Yamaguchi, Tsuyoshi;Nakahara, Eiichiro;Koda, Shinobu. And the article was included in Journal of Physical Chemistry B in 2014.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The frequency-dependent viscosity and conductivity of various ionic liquids were measured exptl., and their mean relaxation times were determined The relaxation times of the viscosity and conductivity were approx. correlated with their resp. zero-frequency limiting values. The Walden products, however, appeared to have no correlation with the ratio of the relaxation time of viscosity to that of conductivity in general. When the alkyl chain of the cation is as short as Bu, more viscous ionic liquids tend to show larger difference between two relaxation times and larger Walden products. Lengthening the alkyl chain of the cation decreases the Walden product while slightly increasing the relaxation time ratio, which was elucidated in terms of the decrease in the high-frequency shear modulus. In addition, the contribution of the mesoscopic structure to viscosity was suggested in the case of the ionic liquid with the longest alkyl chain studied in this work, 1-dodecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide.

Relationship between mesoscale dynamics and shear relaxation of ionic liquids with long alkyl chain was written by Yamaguchi, Tsuyoshi;Mikawa, Ken-ichi;Koda, Shinobu;Fujii, Kenta;Endo, Hitoshi;Shibayama, Mitsuhoro;Hamano, Hiroshi;Umebayashi, Yasuhiro. And the article was included in Journal of Chemical Physics in 2012.SDS of cas: 404001-48-5 This article mentions the following:

The shear relaxation spectra of three imidazolium-based ionic liquids, 1-methyl-3-octylimidazolium chloride (C₈mimCl), 1-methyl-3-octylimidazolium hexafluorophosphate (C₈mimPF₆), and 1-dodecyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (C₁₂mimTFSA) were measured and compared with the intermediate scattering functions determined with neutron spin echo (NSE) spectroscopy. The shear relaxation is slower than that predicted from the relaxation of the main peak of the structure factor that is common to other mol. liquids, whereas it is faster than that from the relaxation of the pre-peak, that corresponds to the correlation length of about 10 nm specific to ionic liquids with an intermediately long alkyl chain. The role of the pre-peak structure in the mechanism of shear viscosity of ionic liquids is discussed based on the comparison between NSE and shear relaxations. (c) 2012 American Institute of Physics.

Measurement and PC-SAFT modelling of three-phase behaviour was written by Rodriguez-Palmeiro, Iago;Rodriguez, Oscar;Soto, Ana;Held, Christoph. And the article was included in Physical Chemistry Chemical Physics in 2015.Related Products of 404001-48-5 This article mentions the following:

Modeling of multi-component systems with complex interactions is an ongoing challenge in thermodn. due to their great relevance in industry and academia. Systems that build three liquid phases are found in many interesting applications (separation processes, triphasic catalysis…). Among them, the surfactant flooding method for enhanced oil recovery is noticeable. In this method, a stable solution of water, surfactants, co-surfactants, salts and other components is injected into the reservoir. The optimal formulation of this surfactant system is associated with a three-phase behavior in which the interfacial tension becomes significantly low. In this work, the PC-SAFT equation of state was used for the first time to predict the equilibrium involved in triphasic systems using solely pure-component parameters. The model without any fitting parameter was able to predict the three-phase behavior. A great agreement between exptl. and predicted compositions for (water + [C₁₀mim][NTf₂] + n-dodecane) and (water + [C₁₂mim][NTf₂] + n-dodecane) ternary systems at 298.15 K and atm. pressure was found. At 348.15 K slightly higher deviations were found, which can be compensated by the introduction of just one binary interaction parameter. The success of this achievement could mean an important advancement in upstream oil operations, enabling a faster and cheaper method to carry out an initial screening of potential surfactants.

Determining the composition of the vacuum-liquid interface in ionic-liquid mixtures was written by Smoll, E. J. Jr.;Tesa-Serrate, M. A.;Purcell, S. M.;D’Andrea, L.;Bruce, D. W.;Slattery, J. M.;Costen, M. L.;Minton, T. K.;McKendrick, K. G.. And the article was included in Faraday Discussions in 2018.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The vacuum-liquid interfaces of a number of ionic-liquid mixtures have been investigated using the combination of reactive-atom scattering with laser-induced fluorescence detection (RAS-LIF), selected surface tension measurements, and mol. dynamics (MD) simulations. The mixtures are based on the widespread 1-alkyl-3-methylimidazolium ([C_nmim]⁺) cation, including mixed cations which differ in chain length or chem. functionality with a common anion; and different anions for a common cation. RAS-LIF results imply that the surface compositions exhibit a general form of non-stoichiometric behavior that mimics the well-known Henry’s and Raoult’s laws at low and high mole fraction, resp. The extended Langmuir model provides a moderately good single-parameter fit, but higher-order terms are required for an accurate description. The quant. relationship between RAS-LIF and surface tension, which probes the surface composition only indirectly, is explored for mixtures of [C₂mim]⁺ and [C₁₂mim]⁺ with a common bis(trifluoromethylsulfonyl)imide ([NTf₂]^–) anion. Extended Langmuir model fits to surface tension data are broadly consistent with those to RAS-LIF; however, several other common approaches to extracting surface compositions from measured surface tensions result in much larger discrepancies. MD simulations suggest that RAS-LIF faithfully reports on the alkyl-chain exposure at the surface, which is only subtly modified by composition-dependent structural reorganisation.

Solubility of argon, krypton and xenon in ionic liquids was written by Song, Tangqiumei;Lubben, Michael J.;Brennecke, Joan F.. And the article was included in Fluid Phase Equilibria in 2020.SDS of cas: 404001-48-5 This article mentions the following:

This work presents the results of argon, krypton and xenon solubility measurements in a series of imidazolium-based ionic liquids (ILs) with the bis(trifluoromethylsulfonyl)imide ([TFSI]^–), 2-cyanopyrrolide ([2CNPyr]^–) and hexafluorophosphate ([PF₆]^–) anions, as well as ILs with the trihexyltetradecylphosphonium ([P₆₆₆₁₄]⁺) cation paired with 2-cyanopyrrolide ([2CNPyr]^–) and 1,2,4-triazolide ([4-triaz]^–) anions. The solubility of Ar was measured at 295 K and pressures up to 9 MPa, Kr was also measured at 295 K and pressures up to 5 MPa, and Xe was measured at temperatures from 295 K to 333 K and pressures up to 0.3 MPa. Noble gases are simple nonpolar, spherical atoms with varying sizes and polarizabilities. While their separation, especially from air, is relevant because they have uses in providing inert atmospheres and in fluorescent lights, the main purpose of this study is to gain fundamental understanding of the influence of size and polarizability on gas solubility in ILs. As a result, the temperature effects on the dissolution of argon and xenon were investigated in order to determine enthalpies of dissolution The solubilities of noble gases correlate strongly with the IL molar volume, indicating the importance of entropic interactions, because free volume generally correlates with molar volume. While van der Waals interactions are the dominant forces between smaller noble gas (like Ar) and the IL, Xe has sufficiently high polarizability that both van der Waals and induced dipole-dipole interactions contribute to its dissolution In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5SDS of cas: 404001-48-5).

The ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, [C₂mim][Tf₂N], a non-polar phase in conjunction with polar ethylene glycol (EG), forms microemulsions stabilized by the surface active ionic liquid (SAIL), N-methyl-N-alkylimidazolium chloride, [C_nmim][Cl], where n = 8, 12, and 16, plus decanol as co-surfactant. Ternary system phase behavior was examined and three microemulsion zones (polar-in-IL, bi-continuous, IL-in-polar) were identified using elec. conductivity measurements. Alkyl chain length effect on phase behavior is discussed in detail. The one-phase microemulsion region decreased with increased SAIL alkyl chain length. Microstructural characteristics were assessed by Fourier transform IR and NMR spectroscopies. In-microemulsion reverse micelle micropolarity was examined by UV-vis spectroscopy with methyl orange as a polarity probe. Solvent microemulsion solvent relaxation dynamics were assessed by steady-state and time-resolved fluorescence spectroscopy using coumarin 153 (C-153) as fluorescence probe for different microemulsion compositions Dynamic light scattering measurements (DLS) showed the expansion of reverse micelles formed by [C_nmim][Cl] in non-polar [C₂mim][Tf₂N] upon addition of a polar component.

The use of smart technologies in the daily lives, from smart phones to auto-dimming windows to touch sensors, has become pervasive. With growing desire for these devices to be conformable and flexible, traditional materials are being replaced to create a class of products known as active organic electronic devices (OEDs). These new devices owe their ability to switch elec. and/or optical function to the intimate interaction between an inherently conducting polymer and electrolyte, typically an ionic liquid Herein, the authors provide the 1st observations that specific ionic liquids can reduce or oxidize conducting polymers upon intimate contact in the absence of any elec. stimuli. The ability to reduce or oxidize the inherently conducting polymer depends on the cation and anion pair within the ionic liquid Extending the utility of this phenomenon is made by fabricating OEDs such as prototype fuel cells, supercapacitors and smart windows.
