Abstract: Cold flow properties of Iranian crude oil have been investigated by two different imidazolium ionic liquids including 1-dodecyl-3-methylimidazolium reduce the pour point up to bis(trifluoromethanesulfonyl) imide ([C₁₂min][NTf₂]) and 1-tetradecyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide ([C₁₄min][NTf₂]). ([C₁₄min][NTf₂]) showed high ability to 12°C optimal performance by addition of 2000 ppm. Wax crystallization behavior of untreated and treated crude oil was monitored using differential scanning calorimetry (DSC) and the polarized optical microscopy (POM). Results from DSC and POM revealed that the presence of both ILs changes the process of crystallization and extends wax precipitation time. Furthermore, rheol. behavior of the crude oil was improved and viscosity was decreased by 73% at 23.5°C and 87% at 15°C by addition of [C₁₄mim][NTf₂].

Enhancing the solar energy conversion and harvesting characteristics of multiwalled carbon nanotubes-modified 1-hexyl-3-methyl-imidazolium cation ionic liquids was written by Boldoo, Tsogtbilegt;Lee, Minjung;Cho, Honghyun. And the article was included in International Journal of Energy Research in 2022.COA of Formula: C18H31F6N3O4S2 This article mentions the following:

The concept of solar energy absorption or photothermal energy conversion of nanofluids as a working fluid is a promising idea utilized in various applications. However, the lack of diversity of the base agents restricts the usage of solar thermal conversion systems in extreme conditions such as extreme cold or hot environments. The ionic liquids were used as a base agent to broaden the applicable conditions of the solar thermal conversion system considering the remarkable favorable characteristics of ionic liquids In this study, key factors of solar energy conversion characteristics and performance of the various 1-hexyl-3-methylimidazolium cation-based ionic liquids and MWCNT nanoparticle-enhanced ionic liquids (NEILs) were exptl. investigated. This study dives deep into the optical properties of the ionic liquids compared to the previous studies in the open literature. In the manufacturing process, MWCNT nanoparticles are dispersed in various ionic liquids at 20 kHz and coated with the Gum-Arabic. It was found that 1-hexyl-3-methylimidazolium cation-based pure room temperature ionic liquids were almost transparent in the visible light spectrum with nearly 0% absorbance; however, adding a small amount of addnl. MWCNT nanoparticles sharply increased the absorbance rate up to nearly 100% (Fâˆ?). Besides, the transmittance of the MWCNT NEILs decreased with the increasing concentration Under the simulated solar light, the final temperature of the samples increased with the increasing concentration of MWCNT NEIL. Moreover, the maximum photothermal energy conversion efficiency (η_PEC) of each MWCNT NEILs was 38.0%, 40.9%, 40.2%, and 39.8% in the case of [HMIM][Tf₂N], [HMIM][TfO], [HMIM][Pf₆], and [C₁₂MIM][Tf₂N], resp., at a concentration and operating time of 1 wt% and 7200 s. In addition, SER value sharply increased with the increasing nanoparticle concentration, and it almost doubled compared to the base agents. Furthermore, the nanoparticle concentration affects the solar energy absorption capability of ionic liquids more than anions in their chem. structure. This study can deliver the necessary data to design a direct absorption solar thermal collector using ionic liquids, which are new green designer working fluids. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5COA of Formula: C18H31F6N3O4S2).

Interfaces of ionic liquids and aqueous solutions exhibit stable elec. potentials over a wide range of aqueous electrolyte concentrations This makes ionic liquids suitable as bridge materials that sep. in electroanal. measurements the reference electrode from samples with low and/or unknown ionic strengths. However, methods for the preparation of ionic liquid-based reference electrodes were not explored widely. The authors have designed a convenient and reliable synthesis of ionic liquid-based reference electrodes by polymerization-induced microphase separation This technique allows for a facile, single-pot synthesis of ready-to-use reference electrodes that incorporate ion conducting nanochannels filled with either 1-octyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide or 1-dodecyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide as ionic liquid, supported by a mech. robust cross-linked polystyrene phase. This synthesis procedure allows for the straightforward design of various reference electrode geometries. These reference electrodes exhibit a low resistance as well as good reference potential stability and reproducibility when immersed into aqueous solutions varying from deionized, purified H₂O to 100 mM KCl, while requiring no correction for liquid junction potentials.

Structure of Alkylimidazolium-Based Ionic Liquids at the Interface with Vacuum and Water-A Molecular Dynamics Study was written by Konieczny, Jan K.;Szefczyk, Borys. And the article was included in Journal of Physical Chemistry B in 2015.Electric Literature of C18H31F6N3O4S2 This article mentions the following:

Ionic liquid (IL) interfaces with vacuum and water are studied by means of classical mol. dynamics simulations. Five ILs are compared: [C₂mim][TfO], [C₁₂mim][TfO], [C₂mim][NTf₂], [C₈mim][NTf₂] and [C₁₂mim][NTf₂], where [C₂mim], [C₈mim] and [C₁₂mim] stand for 1-ethyl-, 1-octyl- and 1-dodecyl-3-methylimidazolium cation. Phys. properties – d., thermal expansion coefficient, compressibility, surface tension, heat of vaporization, self-diffusion coefficient, elec. conductivity and viscosity – are calculated and validated against exptl. values. The structure of the interfaces is compared in terms of the orientation of the mols. and segregation into layers. It is observed that ILs with short alkyl chains orient at the surface; however, there is no single preferred orientation. ILs with longer chains, on the other hand, orient with alkyl chains protruding into the vacuum at the IL/vacuum interface and into the bulk IL, at the IL/water interface. Anions and water mols. tend to associate with polar imidazolium groups.

Effect of the alkyl chain length in 1-alkyl-3-methylimidazolium ionic liquids on inter-molecular interactions and rotational dynamics was written by Garaga, Mounesha N.;Nayeri, Moheb;Martinelli, Anna. And the article was included in Journal of Molecular Liquids in 2015.Application of 404001-48-5 This article mentions the following:

We have investigated the effect of increasing the alkyl chain length, n, in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (C_nC₁ImTFSI) ionic liquids on both inter-mol. interactions and rotational dynamics. This has been addressed by combining 1D ¹H and T₁ relaxation NMR spectroscopy with vibrational spectroscopy, including both Raman and IR. We find that the vibrational modes sensitive to inter-mol. interactions change only slightly with an increased alkyl chain length, with negligible changes for chains longer than the hexyl (n > 6). This is nicely corroborated by ¹H chem. shift changes, in particular of the aromatic protons. The ¹³C correlation times, τ_c, of the individual carbon atoms reveal that while the overall rotational mobility decreases with n, different dynamical properties are observed with the polar domains becoming the most dynamic and the imidazolium ring and its closest chain segment the most rigid. We conclude that the formation of segregated nano-domains in C_nC₁ImTFSI is accompanied by the formation of nano-dynamical heterogeneities, which can explain why classical theories fail to describe the dependence on n of macroscopically observed properties.

Small nickel nanoparticle arrays from long chain imidazolium ionic liquids was written by Yang, Mei;Campbell, Paul S.;Santini, Catherine C.;Mudring, Anja-Verena. And the article was included in Nanoscale in 2014.SDS of cas: 404001-48-5 This article mentions the following:

Six long chain alkyl mono- and bi-cationic imidazolium based salts with bis(trifluoromethylsulfonyl)imide (NTf₂^–) as the anion were synthesized and characterized. The single crystal structure of 1-methyl-3-octadecylimidazolium bis(trifluoromethylsulfonyl)imide could be obtained by x-ray anal. All these long chain alkyl imidazolium based ILs were applied in the synthesis of Ni nanoparticles via chem. decomposition of an organometallic precursor of Ni. In these media, spontaneous decomposition of Ni(COD)₂ (COD = 1,5-cyclooctadiene) in the absence of H₂ occurred giving small NPs (â‰? nm) with narrow size distributions. Formation of regularly interspaced NP arrays was also observed in long chain ILs. Such array formation could be interesting for potential applications such as C nanotube growth.

Reactive-Atom Scattering from Liquid Crystals at the Liquid-Vacuum Interface: [C₁₂mim][BF₄] and 4-Cyano-4′-Octylbiphenyl (8CB) was written by Purcell, Simon M.;Tesa-Serrate, Maria A.;Marshall, Brooks C.;Bruce, Duncan W.;D’Andrea, Lucia;Costen, Matthew L.;Slattery, John M.;Smoll, Eric J.;Minton, Timothy K.;McKendrick, Kenneth G.. And the article was included in Langmuir in 2016.HPLC of Formula: 404001-48-5 This article mentions the following:

Two complementary approaches were used to study the liquid-vacuum interface of the liquid-crystalline ionic liquid 1-dodecyl-3-methylimidazolium tetrafluoroborate ([C₁₂mim][BF₄]) in the smectic A (SmA) and isotropic phases. O atoms with two distinct incident translational energies were scattered from the surface of [C₁₂mim][BF₄]. Angle-dependent time-of-flight distributions and OH yields, resp., were recorded from high- and low-energy O atoms. There were no significant changes in the measurements using either approach, nor the properties derived from them, accompanying the transition from the SmA to the isotropic phase. This indicates that the surface structure of [C₁₂mim][BF₄] remains essentially unchanged across the phase boundary, implying that the bulk order and surface structure are not strongly correlated for this material. This effect is ascribed to the strong propensity for the outer surfaces of ionic liquids to be dominated by alkyl chains, over an underlying layer rich in anions and cation head groups, whether or not the bulk material is a liquid crystal. In a comparative study, the OH yield from the surface of the liquid crystal, 8CB, was found to be affected by the bulk order, showing a surprising step increase at the SmA-nematic transition temperature, whose origin is the subject of speculation.

Predictive QSAR models for the inhibitors of B. subtilis and Ps. aeruginosa among imidazolium-based ionic liquids were developed using literary data. The regression QSAR models were created through Artificial Neural Network and k-nearest neighbor procedures. The classification QSAR models were constructed using WEKA-RF (random forest) method. The predictive ability of the models was tested by fivefold cross-validation; giving q² = 0.77-0.92 for regression models and accuracy 83-88% for classification models. Twenty synthesized samples of 1,3-dialkylimidazolium ionic liquids with predictive value of activity level of antimicrobial potential were evaluated. For all asym. 1,3-dialkylimidazolium ionic liquids, only compounds containing at least one radical with alkyl chain length of 12 carbon atoms showed high antibacterial activity. However, the activity of sym. 1,3-dialkylimidazolium salts was found to have opposite relationship with the length of aliphatic radical being maximum for compounds based on 1,3-dioctylimidazolium cation. The obtained exptl. results suggested that the application of classification QSAR models is more accurate for the prediction of activity of new imidazolium-based ILs as potential antibacterials.

The biocatalytic synthesis of monoacylglycerides (MAGs) was carried out by the direct esterification of fatty acids (i.e. capric, lauric, myristic, palmitic and oleic acids, resp.) with glycerol in different ionic liquids (ILs) based on cations with long alkyl side-chains (e.g. 1-hexadecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [C₁₆mim][NTf₂], 1-dodecyl-3-methylimidazolium tetrafluoroborate [C₁₂mim][BF₄], etc.). Although all ILs have been shown as suitable reaction media for Novozym 435-catalyzed esterification of glycerol with free fatty acids, a high selectivity of MAGs was only observed in the [C₁₂mim][BF₄] case (e.g. up to 100% selectivity and 100% yield for monolaurin). Furthermore, as these ILs are temperature switchable ionic liquid/solid phases that behave as sponge-like systems, a straightforward protocol for IL-free MAG recovery, based on iterative centrifugations at controlled temperature, has been developed.
