Reported is the spontaneous formation of nano-sized ionic liquid/water (IL/W) emulsions in a simple system solely composed of an IL and aqueous solution of an inorganic salt. The IL ions play a dual role, that of both a surfactant and the dispersed phase. No extra surfactant is needed to promote emulsification. Droplets generation at the IL/W interface is captured by nanoparticulate and porous films that imprint the morphol. of this unstable interface. The emulsion droplets are employed to create core-shell microcrystals with potential functionality.

Systematic estimation and interpretation of fractional free volume in 1-alkyl-3-methylimidazolium-based ionic liquids was written by Endo, Takatsugu;Nishisaka, Yuji;Kin, Youn;Kimura, Yoshifumi. And the article was included in Fluid Phase Equilibria in 2019.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

With the aim of providing a plausible explanation for fractional free volume (FFV) behavior in ionic liquids (ILs) such as 1-alkyl-3-methylimidazolium-based cations paired with common anions like [BF₄]^–, [PF₆]^–, and bis(trifluoromethane)sulfonamide ([NTf₂]^–), we comprehensively estimated the van der Waals volume of the ions and subsequently determined the FFV behavior present within these liquids with the aid of quantum chem. calculations Unlike the values seen in previous studies, our results showed an increase in the FFV character of the IL under investigation when either the cations alkyl chain was lengthened and/or the size of the anion was expanded. The sizes of cations and anions present in the IL were shown to affect the FFV values in different ways: whereas the effect of the anions size could be accounted for by looking at changes in the Coulomb interaction between cations and anions in the polar (charge localized) domains, the effect exerted by the alkyl chain was found to be related to the alkyl chains dependence on the FFV obtained for alkanes due to the introduction of non-polar (alkyl group aggregated) domains to ILs with increasing alkyl chain lengths. An empirical equation was proposed in order to calculate FFV values for alkyl-imidazolium-based ILs.

Cation Symmetry effect on the Volatility of Ionic Liquids was written by Rocha, Marisa A. A.;Coutinho, Joao A. P.;Santos, Luis M. N. B. F.. And the article was included in Journal of Physical Chemistry B in 2012.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

This work reports the first data for the vapor pressures at several temperatures of the ionic liquids, [C_N/2C_N/2i.m.][NTf₂] (N = 4, 6, 8, 10, 12) measured using a Knudsen effusion apparatus combined with a quartz crystal microbalance. The morphol. and the thermodn. parameters of vaporization derived from the vapor pressures, are compared with those for the 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide series, [C_N-1C₁i.m.][NTf₂] (N = 3 – 9, 11, and 13). It was found that the volatility of [C_N/2C_N/2i.m.][NTf₂] series is significantly higher than the asym. cation ILs with the same total number of carbons in the alkyl side chains, [C_N-1C₁i.m.][NTf₂]. The observed higher volatility is related with the lower enthalpy of vaporization. The sym. cation, [C_N/2C_N/2i.m.][NTf₂], presents lower entropies of vaporization compared with the asym. [C_N-1C₁i.m.][NTf₂], indicating an increase of the absolute liquid entropy in the sym. cation ILs, being a reflection of a change of the ion dynamics in the IL liquid phase. Moreover both the enthalpy and entropy of vaporization of the [C_N/2C_N/2i.m.][NTf₂] ILs, present a clear odd-even effect with higher enthalpies/entropies of vaporization for the odd number of carbons in each alkyl chain ([C₃C₃i.m.][NTf₂] and [C₅C₅i.m.][NTf₂]).

Further understanding of the multiple equilibria interaction pattern between ionic liquid and 尾-cyclodextrin was written by Zhang, Jingjing;Shi, Jianfeng;Shen, Xinghai. And the article was included in Journal of Inclusion Phenomena and Macrocyclic Chemistry in 2014.Application of 404001-48-5 This article mentions the following:

The interactions of the ionic liquids 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (C_nmimTf₂N, n = 2, 4, 6, 8, 10, 12) with 尾-cyclodextrin (尾-CD) in aqueous solutions are investigated in this work. The stoichiometry and apparent association constants are obtained by competitive fluorescence method and isothermal titration calorimetry (ITC). The results show that C₂mimTf₂N, C₄mimTf₂N, and C₆mimTf₂N mainly form 1:1 (guest:host) inclusion complexes with 尾-CD, whereas C₈mimTf₂N, C₁₀mimTf₂N, and C₁₂mimTf₂N form both 1:1 and 1:2 inclusion complexes, the latter of which are mainly attributed to the formation of the C_nmim⁺-2尾-CD complexes. Besides, Tf₂N^– only forms the 1:1 complex with 尾-CD owing to a charge resonance structure that breaks the symmetry of the structure of Tf₂N^–, which is proved by Fourier transform IR spectra. The thermodn. parameters obtained by ITC reveal that the formation of the inclusion complexes are enthalpy-controlled for C₂mimTf₂N, C₄mimTf₂N, and C₆mimTf₂N, while for the C₈mimTf₂N/尾-CD system, the process becomes entropy and enthalpy driven. Based on high-resolution mass spectrometry used with electrospray ionization results, the interaction between C_nmimTf₂N and 尾-CD is found to follow the multiple equilibrium interaction pattern which was suggested in our previous work.

Alkylimidazolium Based Ionic Liquids: Impact of Cation Symmetry on Their Nanoscale Structural Organization was written by Rocha, Marisa A. A.;Neves, Catarina M. S. S.;Freire, Mara G.;Russina, Olga;Triolo, Alessandro;Coutinho, Joao A. P.;Santos, Luis M. N. B. F.. And the article was included in Journal of Physical Chemistry B in 2013.Synthetic Route of C18H31F6N3O4S2 This article mentions the following:

Aiming at evaluating the impact of the cation symmetry on the nanostructuration of ionic liquids (ILs), in this work, densities and viscosities as a function of temperature and small-wide angle X-ray scattering (SWAXS) patterns at ambient conditions were determined and analyzed for 1-alkyl-3-methylimidazolium bis-(trifluoromethylsulfonyl)-imide (asym.) and 1,3-dialkylimidazolium bis-(trifluoromethylsulfonyl)-imide (sym.) series of ionic liquids The sym. IL series, [C_N/2C_N/2i.m.]-[NTf₂], presents lower viscosities than the asym. [C_N-1C₁i.m.]-[NTf₂] counterparts. For ionic liquids from [C₁C₁i.m.]-[NTf₂] to [C₆C₆i.m.]-[NTf₂], an odd-even effect in the viscosity along the cation alkyl side chain length was observed, in contrast with a linear increase found for the ones ranging between [C₆C₆i.m.]-[NTf₂] and [C₁₀C₁₀i.m.]-[NTf₂]. The anal. of the viscosity data along the alkyl side chain length reveals a trend shift that occurs at [C₆C₁i.m.]-[NTf₂] for the asym. series and at [C₆C₆i.m.]-[NTf₂] for the sym. series. These results are further supported by SWAXS measurements at ambient conditions. The gathered data indicate that both asym. and sym. members are characterized by the occurrence of a distinct degree of mesoscopic structural organization above a given threshold in the side alkyl chain length, regardless the cation symmetry. The data also highlight a difference in the alkyl chain dependence of the mesoscopic cluster sizes for sym. and asym. cations, reflecting a different degree of interdigitation of the aliphatic tails in the two families. The trend shift found in this work is related to the structural segregation in the liquid after a critical alkyl length size (CALS) is attained and has particular relevance in the cation structural isomerism with higher symmetry.

Ionic liquids as coagents for sulfur vulcanization of butadiene-styrene elastomer filled with carbon black was written by Maciejewska, Magdalena;Zaborski, Marian. And the article was included in Polymer Bulletin (Heidelberg, Germany) in 2018.Application of 404001-48-5 This article mentions the following:

The aim of this work was to study the activity of several alkylimidazolium salts of bis(trifluoromethylsulfonyl)imides to obtain a very fast vulcanization of the butadiene-styrene (SBR) elastomer. Ionic liquids (ILs) such as alkylimidazolium salts with ethyl-, propyl-, butyl-, hexyl-, decyl-, dodecyl-, and hexadecyl chains in the cation together with nanosized zinc oxide are used to develop elastomer composites with very short vulcanization time and a reduced amount of vulcanization activator. In this article, we discuss the effect of the ILs with respect to the length of alkyl chain in their cation on the vulcanization kinetics of rubber compounds The influence of ILs on the crosslink d. as well as the mech. properties of the vulcanizates and their resistance to thermo-oxidative and UV aging were also studied. ILs resulted in a shortened optimal vulcanization time and reduced the onset vulcanization temperature compared to zinc oxide containing rubber compound This is very important from a technol. point of view. A considerable increase in the crosslink d. of vulcanizates was also observed In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application of 404001-48-5).

SANS, ATR-IR, and 1D- and 2D-NMR studies of mixing states of imidazolium-based ionic liquid and aryl solvents was written by Shimomura, Takuya;Inoue, Saori;Kadohata, Shoya;Umecky, Tatsuya;Takamuku, Toshiyuki. And the article was included in Physical Chemistry Chemical Physics in 2013.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The mixing states of imidazolium-based ionic liquid, 1-dodecyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (C₁₂mim⁺TFSA^–), and two aryl solvents toluene and α,α,α-trifluorotoluene (TFT) were clarified on both meso- and microscopic scales using small-angle neutron scattering (SANS) and ATR-IR techniques. To elucidate the interactions between C₁₂mim⁺TFSA^– and aryl solvent mols. from the change in the electron densities of C₁₂mim⁺ and TFSA^–, 1-dimensional-NMR measurements for ¹H and ¹³C atoms were conducted on C₁₂mim⁺TFSA^–-aryl solvent solutions as a function of the aryl solvent mole fraction. The interactions between the dodecyl chain of C₁₂mim⁺ and aryl solvent mols. were observed using 2-dimensional-NMR techniques of ¹H{¹H} ROESY and ¹⁹F{¹H} HOESY. These results were compared with those of benzene solutions previously studied. The SANS measurements showed that toluene is heterogeneously mixed with C₁₂mim⁺TFSA^– as well as benzene. However, the heterogeneity of the toluene solutions is slightly lower than that of the benzene solutions In contrast, TFT is homogeneously mixed with the ionic liquid at least on the present SANS scale. The substituent effects of the three aryl solvent mols. of benzene, toluene, and TFT on the mixing states of the solutions are discussed in terms of the cation-π interaction between the imidazolium and Ph rings and the interaction between the dodecyl group and aryl solvent mols.

Hydrogen bonds of the imidazolium rings of ionic liquids with DMSO studied by NMR, soft X-ray spectroscopy, and SANS was written by Takamuku, Toshiyuki;Tokuda, Takumi;Uchida, Takahiro;Sonoda, Kazuya;Marekha, Bogdan A.;Idrissi, Abdenacer;Takahashi, Osamu;Horikawa, Yuka;Matsumura, Junya;Tokushima, Takashi;Sakurai, Hiroyuki;Kawano, Masahiro;Sadakane, Koichiro;Iwase, Hiroki. And the article was included in Physical Chemistry Chemical Physics in 2018.Category: imidazoles-derivatives This article mentions the following:

The hydrogen bonds of the imidazolium-ring H atoms of ionic liquids (ILs), 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amides ([C_nmim][TFSA], n = 2 to 12 where n represents the alkyl chain length), with the O atom of DMSO (DMSO) have been elucidated using ¹H, ¹³C, and ¹⁵N NMR spectroscopy and soft X-ray absorption and emission spectroscopy (XAS and XES). D. functional theory (DFT) calculations have been performed on an isolated DMSO mol. and two cluster models of [C_nmim]⁺-DMSO by hydrogen bonding to interpret the XES spectra for the [C_nmim][TFSA]-DMSO solutions The ¹H and ¹³C NMR chem. shifts of the imidazolium ring showed that deshielding of the ring H and C atoms is moderate as the DMSO mole fraction x_DMSO increases to ∼0.8; however, it becomes more significant with further increase of x_DMSO. This finding suggests that the hydrogen bonds of the three ring H atoms with the DMSO O atoms are saturated in solutions with x_DMSO increased to ∼0.8. The ¹H and ¹³C chem. shifts of the alkyl chains revealed that the electron densities of the chain H and C atoms gradually decrease with increasing x_DMSO, except for the N¹-bound carbon atom C⁷ of the chain. The ¹⁵N NMR chem. shifts showed that the imidazolium-ring N¹ atom which is bound to the alkyl chain is shielded with increasing x_DMSO in the range from 0 to 0.8 and is then deshielded with further increase of x_DMSO. In contrast, the imidazolium ring N³ atom is simply deshielded with increasing x_DMSO. Thus, the electron densities of the alkyl chain may be condensed at the C⁷ and N¹ atoms of [C_nmim]⁺ by the hydrogen bonding of the ring H atoms with DMSO. The hydrogen bonding of DMSO with the ring results in low-energy shifts of the XES peaks of the O K-edge of DMSO. Small-angle neutron scattering experiments showed that [C_nmim][TFSA] and DMSO are homogeneously mixed with each other on the mesoscopic scale. This results from the strong hydrogen bonds of DMSO with the imidazolium-ring H atoms.
