The state of the art of inclusion complex formation between cyclodextrins and ionic liquids is reported. Mechanisms, stoichiometries, and binding constants are summarized and classified by anion. We investigated the supramol. interactions between the β-cyclodextrin cavity and six ionic liquids based on 1-dodecyl-3-methylimidazolium by affinity capillary electrophoresis and compared the results with those obtained by isothermal titration calorimetry. We show that the presence of basic or acidic buffers leads to a metathesis reaction, underlining the limitation of the affinity capillary electrophoresis technique.

In this research, the effect of imidazolium based ionic liquids as scavengers on reducing and minimizing the amount of hydrogen sulfide in Iranian crude oils has been studied. To improve the quality of crude oil and increasing the value added of producing and exporting of crude oil, firstly, cold stripping was performed and effective parameters of process on the efficiency was investigated. In the next step, four imidazolium-based ionic liquid samples, were synthesized and their effects on reduction of H₂S from four samples of Iranian light crude oils were tested. The design of the experiments and the results of the study were done using the software Minitab 14. For this purpose, the effect of the parameters of the ratio of scavenger concentration, temperature and contact time with crude oil on the reduction of H₂S was studied. The results of the study show that ionic liquid scavenger yields a better efficiency; with optimal conditions (concentration of 1200 ppm, temperature of 45° C in 20 min of time) H₂S reduces in crude oil from 550 to less than 15 ppm.

Insights into the influence of the molecular structures of fluorinated ionic liquids on their thermophysical properties. A soft-SAFT based approach was written by Ferreira, Margarida L.;Araujo, Joao M. M.;Pereiro, Ana B.;Vega, Lourdes F.. And the article was included in Physical Chemistry Chemical Physics in 2019.Recommanded Product: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

Fluorinated ionic liquids (FILs) are a unique family of ionic liquids with remarkable properties, including the formation of 3 nano-segregated domains, which are very attractive for several emerging applications. However, the amount of available exptl. data to fully characterize them is very scarce. The authors propose a systematic methodol. to build FIL transferable mol. models within the soft-SAFT framework to describe the behavior of FILs and their mixtures A total of 38 FILs (pyridinium- and imidazolium-based FILs conjugated with fluorinated anions such as [N(CF₃SO₂)₂]^–, [CF₃SO₃]^–, [CF₃CO₂]^–, [C₄F₉SO₃]^– and [C₄F₉CO₂]^–) were modeled for this purpose using available data, paying special attention to the phys. meaning of the parameters. The models are used to obtain mol. insights into the influence of the anion and cation mol. structures on the thermophys. properties of the FILs. The anion and anion fluorination are the leading features in the thermophys. properties studied, as captured by soft-SAFT. Models for 3 FILs not included in the parametrization study were built from the transferable parameters, in excellent agreement with exptl. data, underlining the robustness of the soft-SAFT approach. The methodol. presented here allows a direct connection between the mol. characteristics of the FILs, the influence on their behavior, and how this can be captured by a mol.-based equation of state. The procedure allows assembling FIL models with high predictive capabilities in an intuitive way regarding the process of parametrization from the mol. structure, allowing one to characterize their thermophys. behavior where limited exptl. data are available.

Structural effects on thermodynamic behavior and hydrogen bond interactions of water-ionic liquid systems was written by Jiang, Yifan;Wang, Zhenhang;Lei, Zhigang;Yu, Gangqiang. And the article was included in Chemical Engineering Science in 2021.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The relationships between the structure and the thermodn. behavior and the hydrogen bond (HB) interactions in H₂O + ionic liquid (IL) systems were systematically investigated for the first time. Imidazolium-based ILs comprising 1-alkyl-3-methylimidazolium cations ([RMIM]⁺) and various anions such as acetate ([AC]^–), thiocyanate ([SCN]^–), tetrafluoroborate ([BF₄]^–), and bis(trifluoromethylsulfonyl)imide ([Tf₂N]^–) were investigated. The vapor-liquid equilibrium (VLE) of H₂O + IL systems was exptl. determined and predicted by the UNIFAC-Lei model. The results demonstrated that the vapor pressure is mainly dependent on the type of anion and increases slightly with an increase in the cation alkyl chain length. Quantum chem. calculation and wavefunction anal. clearly revealed the relationship between the VLE and the HB interactions. This study provides theor. guidance for designing and screening task-specific ILs for chem. processes such as gas dehydration and dehumidification.

Surface structures of binary mixtures of imidazolium-based ionic liquids using high-resolution Rutherford backscattering spectroscopy and time of flight secondary ion mass spectroscopy was written by Nakajima, Kaoru;Miyashita, Motoki;Suzuki, Motofumi;Kimura, Kenji. And the article was included in Journal of Chemical Physics in 2013.Reference of 404001-48-5 This article mentions the following:

Surface structures of binary mixtures of imidazolium-based ionic liquids having a common anion (bis(trifluoromethanesulfonyl)imide (TFSI), namely C₂MIM_1-xC₁₀MIM_xTFSI (x = 0.5 and 0.1), were studied using high-resolution Rutherford backscattering spectroscopy (HRBS) and time of flight secondary ion mass spectroscopy (TOF-SIMS). Although both measurements show surface segregation of C₁₀MIM the degrees of the segregation are different. The surface fraction x_surf of C₁₀MIM is estimated to be 0.6 and 0.18 by HRBS for x = 0.5 and 0.1, resp. On the other hand, TOF-SIMS indicates much stronger surface segregation, namely x_surf = 0.83 and 0.42 for x = 0.5 and 0.1, resp. The observed discrepancy can be attributed to the difference in the probing depth between HRBS and TOF-SIMS. The observed surface segregation can be roughly explained in terms of surface tension.

Heterogeneous Structures of Ionic Liquids as Probed by CO Rotation with Nuclear Magnetic Resonance Relaxation Analysis and Molecular Dynamics Simulations was written by Endo, Takatsugu;Sumida, Hiroki;Fujii, Kaori;Takahashi, Kenji;Kimura, Yoshifumi. And the article was included in Journal of Physical Chemistry B in 2020.Electric Literature of C18H31F6N3O4S2 This article mentions the following:

The rotational dynamics of carbon monoxide (CO) in ionic liquids (ILs) was investigated by NMR relaxation measurements and mol. dynamics (MD) simulations. NMR spin-lattice relaxation time measurements were performed for ¹⁷O-enriched CO in 10 ILs (four imidazolium-cation-based, four phosphonium-cation-based, and two ammonium-cation-based ILs, all paired with the bis(trifluorosulfonylmethane)imide anion). In combination with previously reported data for five ILs and viscosity data, our results indicated that the obtained rotational relaxation times (τ_2R) were much smaller than those predicted using the Stokes-Einstein-Debye (SED) theory. For the same viscosity/temperature values, the τ_2R^-1 value increased linearly with increasing carbon number of the alkyl group in the cation. The deviation from the SED equation was due to the insensitivity of τ_2R to the carbon number, even though a higher carbon number generally leads to higher viscosity values for ILs. To investigate the unique rotational properties of CO in the ILs, MD simulations were performed on five representative ILs (two imidazolium, two phosphonium, and one ammonium) containing CO solutes. From rotational correlation function analyses, the CO rotation mainly occurred in a free rotation-like manner within 1 ps, which explained the relative insensitivity of CO rotation to viscosity. In the subsequent time scale (>1 ps), the minor component of the CO rotation was discriminated among different ILs. It was strongly suggested that, because CO preferably locates in the outer part of the alkyl groups in the cation, the slow CO rotation is correlated with the outer alkyl dynamics, which are decoupled from the whole cation rotation.

Six polar oils suitable for use in lubrication were utilized as base oil. Solubility tests were performed by using turbidimetry, and corrosion was checked at 4 volume/volume% by examining the roughness and chem. composition of the surface after 21 days.

Millettia pinnata seed oil has been identified as a promising sustainable feedstock for biodiesel production Oils extracted from the seeds grown in freshwater and seawater habitats showed no significant differences in their physicochem. properties. The enzymic methanolysis of the oil has been investigated in the ionic liquid (IL) [BMIm][PF₆] (1-butyl-3-methylimidazolium hexafluorophosphate) as compared to tert-butanol, catalyzed by Penicillium expansum lipase (PEL) and Candida antarctica lipase B (Novozym 435). Under optimal conditions, PEL induced much higher yields in the IL than in tert-butanol, while in the IL PEL-catalyzed conversions were higher than those catalyzed by Novozym 435. The catalytic processes were improved by recycling both the enzyme (Novozym 435) and the IL ([BMIm][PF₆]) and by searching for new enzymes and new ILs. The impact of ILs on biodiesel production has been discussed, and the interactions between the IL, the substrate, and the enzyme are believed to play an important role in governing the conversion.

A series of different cationic structures based on 1-alkyl-3-methylimidazolium were combined with a single anion, bis(trifluoromethylsulfonyl)imide (C_nmimNTf₂, n = 1 to 12) for analyzing the quality of COSMO-RS based estimations For this purpose, we have studied the structure as well as the estimations of several properties of one ionic liquid (IL). These estimations are obtained from polarization charge distribution in which the IL is embedded. Special attention has been paid to the effect of the dielec. constant value in the predictions. For this purpose, polarization charge d. has been modeled using several values of dielec. constant, and properties have been estimated in each case. Thus, σ-profiles and, σ-potentials have been computed and used with COSMO-RS for estimating vapor pressure, as a function of temperature, as well as theor. values of vaporization enthalpy, d., and viscosity at 298.15 K. The influence of the length of the alkyl chain of ionic liquid in the estimation of these properties has also been tested. Finally, the results have been compared with exptl. data.
