Binary mixtures of homologous room-temperature ionic liquids: Temperature and composition evolution of the nanoscale structure was written by Pontoni, Diego;DiMichiel, Marco;Deutsch, Moshe. And the article was included in Journal of Molecular Liquids in 2021.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

Using X-ray scattering from binary mixtures of [C_nmim][NTf₂] room temperature ionic liquids (RTILs) with n = 8,12 we study their nanoscale layering and its evolution with temperature T and mole fraction x of [C₈mim][NTf₂]. The layers’ lateral structure, dominated by the common headgroups’ Coulomb interaction in the layer’s polar slab, and by the chain-chain van der Waals interaction in the apolar slab, hardly changes. However, the longitudinal layer spacing, dI, decreases with x, exhibiting domination by [C₁₂mim][NTf₂] at least up to x â‰?0.5. The layering order’s range decreases uniformly with x. dI is found to deviate pos. from an ideal mixture spacing by up to â‰?%. The lateral spacings’ deviations are 10-fold smaller, implying the nanoscale excess volume to be also â‰?%, 100-fold larger than those obtained from macroscopic molar d. measurements. This gap is probably bridged at the larger length scales of these RTILs’ hierarchical order. Increasing T decreases the d_I deviations, but only marginally. The pos., and T-decreasing, d_I deviations from ideality contrast strongly with the neg., 100-fold smaller, and T-increasing, deviations found for liquid normal-alkane mixtures of the same lengths, but fully agree with the pos. similar-percent deviations obtained from the modified Vegard’s law for soft-solid rotator phases of binary mixtures of alkanes and of alcs. These results attest against a liquid-like chain packing in the apolar slab of the RTILs, but strongly support an interdigitated, roughly layer normal, chain packing. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide

Making Sense of Enthalpy of Vaporization Trends for Ionic Liquids: New Experimental and Simulation Data Show a Simple Linear Relationship and Help Reconcile Previous Data was written by Verevkin, Sergey P.;Zaitsau, Dzmitry H.;Emelyanenko, Vladimir N.;Yermalayeu, Andrei V.;Schick, Christoph;Liu, Hongjun;Maginn, Edward J.;Bulut, Safak;Krossing, Ingo;Kalb, Roland. And the article was included in Journal of Physical Chemistry B in 2013.Category: imidazoles-derivatives This article mentions the following:

Vaporization enthalpy of an ionic liquid (IL) is a key phys. property for applications of ILs as thermofluids and also is useful in developing liquid state theories and validating intermol. potential functions used in mol. modeling of these liquids Compilation of the data for a homologous series of 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide ([C_nmim][NTf₂]) ILs has revealed an embarrassing disarray of literature results. New exptl. data, based on the concurring results from quartz crystal microbalance, thermogravimetric analyses, and mol. dynamics simulation have revealed a clear linear dependence of IL vaporization enthalpies on the chain length of the alkyl group on the cation. Ambiguity of the procedure for extrapolation of vaporization enthalpies to the reference temperature 298 K was found to be a major source of the discrepancies among previous data sets. Two simple methods for temperature adjustment of vaporization enthalpies have been suggested. Resulting vaporization enthalpies obey group additivity, although the values of the additivity parameters for ILs are different from those for mol. compounds In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Category: imidazoles-derivatives).

Responsive Ionogel Surface with Renewable Antibiofouling Properties was written by Ye, Lijun;Chen, Fei;Liu, Jie;Gao, Aiting;Kircher, Gunnar;Liu, Wendong;Kappl, Michael;Wegner, Seraphine;Butt, Hans-Juergen;Steffen, Werner. And the article was included in Macromolecular Rapid Communications in 2019.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The synthesis of ionogels with a responsive, self-replenishing surface for combating biofouling is described. Ionogels are prepared by infiltrating poly(vinylidene fluoride-co-hexafluoropropylene) with binary mixtures of ionic liquids (IL): 1-octadecyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₁₈C₁i.m.][NTf₂], m.p. T_m = 55 °C) and 1-hexyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₆C₁i.m.][NTf₂], T_m = -9 °C). The IL mixtures release spontaneously from the gel matrix and eventually crystallize on the surface. This leads to self-replenishment of the surface of ionogels even after mech. damage. The incorporation of [C₆C₁i.m.][NTf₂] provides the antimicrobial efficacy of ionogels while the crystals of [C₁₈C₁i.m.][NTf₂] serve as a skeleton maintaining [C₆C₁i.m.][NTf₂] on the surface. By heating, the ionogel surface transforms from solid to liquid-infused state-the removal of biofilms/bacteria developed under a long time of colonization is facilitated. The antimicrobial efficacy is maintained even after several cycles of biofilm formation and detachment. This work provides an opportunity to apply ionogels as functional coatings with renewable antibiofouling properties.

Interaction of Ionic Liquids with a Lipid Bilayer: A Biophysical Study of Ionic Liquid Cytotoxicity was written by Jing, Benxin;Lan, Nan;Qiu, Jie;Zhu, Yingxi. And the article was included in Journal of Physical Chemistry B in 2016.Related Products of 404001-48-5 This article mentions the following:

Ionic liquids (ILs) have been widely considered and used as “green solvents” for more than two decades. However, their ecotoxicity results have contradicted this view, as ILs, particularly hydrophobic ones, are reported to exhibit high toxicity. Yet the origin of their toxicol. remains unclear. In this work, we have investigated the interaction of amphiphilic ILs with a lipid bilayer as a model cell membrane to understand their cytotoxicity at a mol. level. By employing fluorescence imaging and light and X-ray scattering techniques, we have found that amphiphilic ILs could disrupt the lipid bilayer by IL insertion, end-capping the hydrophobic edge of the lipid bilayer, and eventually disintegrating the lipid bilayer at high IL concentration The insertion of ILs to cause the swelling of the lipid bilayer shows strong dependence on the hydrophobicity of IL cationic alky chain and anions and is strongly correlated with the reported IL cytotoxicity.

Polysulfone-ionic liquid based membranes for CO₂/N₂ separation with tunable porous surface features was written by Lu, Soon-Chien;Khan, Asim Laeeq;Vankelecom, Ivo F. J.. And the article was included in Journal of Membrane Science in 2016.Reference of 404001-48-5 This article mentions the following:

A surprisingly simple, yet effective blending method for ionic liquids (ILs) and polysulfone (PSf) is presented in this paper. Not only is the IL properly immobilized in the polymer matrix, which is crucial in high-pressure gas separation applications, but this method also produces tunable porous surfaced membranes that can be useful in several other applications. The size and distribution of the pores are dependent on the type and amount of IL incorporated into the PSf. A membrane formation mechanism is proposed to explain the presence of such a regular surface pore structure. Several com. available ILs were tested to examine their compatibility with the polymer, and the CO₂/N₂ gas separation performance of the resulting membrane was screened. ATR-FTIR spectroscopy, FTIR microscopy, and SEM imaging were also employed to shed light on the observed membrane structures. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Reference of 404001-48-5).

Extraction of butan-1-ol from aqueous solution using ionic liquids: An effect of cation revealed by experiments and thermodynamic models was written by Domanska, Urszula;Wlazlo, Michal;Paduszynski, Kamil. And the article was included in Separation and Purification Technology in 2018.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

Production of bio-butanol from biomass by fermentation in an aqueous phase needs new solutions and entrainers for the separation of product. Ionic liquids (ILs) are attractive significant attention as novel, low pressure solvents alternative to conventional organic solvents for biphasic solvent extraction Ternary liquid-liquid equilibrium data are presented for mixtures of {ionic liquid (1) + butan-1-ol (2) + water (3)} at T = 298.15 K and ambient pressure to analyze the performance of the IL in the extraction of butan-1-ol from aqueous phase. The bis{(trifluoromethyl)sulfonyl}amide-based ILs have been studied: octyltriethylammonium bis{(trifluoromethyl)sulfonyl}amide, [N_8,2,2,2][NTf₂], methyltrioctylammonium bis{(trifluoromethyl)sulfonyl}amide, [N_8,8,8,1][NTf₂], 1-dodecyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide, [DoMIM][NTf₂] and 1-hexyloxymethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide, [C₆H₁₃OCH₂MIM][NTf₂]. The results are discussed in terms of the selectivity and the solute distribution ratio of separation for the related systems. The IL with three octyl alkyl chains, [N_8,8,8,1][NTf₂] at the ammonium-based cation shows higher selectivity and the same distribution ratio in comparison to the other ILs in this process. Addnl., the viscosity of [N_8,2,2,2][NTf₂], and d. and viscosity of the best IL, [N_8,8,8,1][NTf₂] were measured for the collection of physico-chem. properties of the ILs used in this work. The non-random two liquid NRTL model was used successfully to correlate the exptl. tie-lines. The prediction of ternary compositions was shown with good precision using COSMO RS for the ILs used in this work and for data from literature. The data and calculations presented here indicate the possible use of the model COSMO RS for the prediction of ternary LLE and of the use of [N_8,8,8,1][NTf₂], as a good solvent for the separation of butan-1-ol from water using solvent extraction In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

The aim of this work was to study the synthesis of tin nanoparticles (NPs) or tin/carbon composites, in room temperature ionic liquids (RTILs), that could be used as structured anode materials for Li-ion batteries. An innovative route for the synthesis of Sn nanoparticles in such media is successfully developed. Compositions, structures, sizes and morphologies of NPs were characterized by high-energy x-ray diffraction (HEXRD), XPS and high-resolution TEM (HRTEM). (i) metallic tetragonal β-Sn was obtained and (ii) the particle size could be tailored by tuning the nature of the RTILs, leading to nano-sized spherical particles with a diameter ranging from 3 to 10 nm depending on synthesis conditions. To study carbon composite materials for Li-ion batteries, Sn nanoparticles were successfully deposited on the surface of multi-wall carbon nanotubes (MWCNT). Also, electrochem. properties were studied in relation to a structural study of the nanocomposites. The poor electrochem. performances as a neg. electrode in Li-ion batteries is due to a significant amount of RTIL trapped within the pores of the nanotubes as revealed by XPS studies. This dramatically affected the gravimetric capacity of the composites and limited the diffusion of lithium. The findings of this work however offer valuable insights into the exciting possibilities for synthesis of novel nano-sized particles and/or alloys (e.g. Sn-Cu, Sn-Co, Sn-Ni, etc.) and the importance of carbon morphol. in metal pulverization during the alloying/dealloying process as well as prevention of ionic liquid trapping.

Ionic liquid-mediated transcutaneous protein delivery with solid-in-oil nanodispersions was written by Araki, Shota;Wakabayashi, Rie;Moniruzzaman, Muhammad;Kamiya, Noriho;Goto, Masahiro. And the article was included in MedChemComm in 2015.Computed Properties of C18H31F6N3O4S2 This article mentions the following:

As a potentially safe and non-invasive vaccination method, transcutaneous immunization represents an attractive alternative to conventional vaccine delivery by injection. However, the development of transcutaneous immunization has remained a challenge for a large number of hydrophilic macromols. including protein and peptide antigens. We report a novel ionic liquid (IL)-mediated transcutaneous vaccine formulation consisting of a solid-in-oil (S/O) nanodispersion of antigen coated with pharmaceutically accepted surfactants dispersed in IL-containing oil. The introduction of the IL [C₁₂mim][Tf₂N] (1-dodecyl-3-Me imidazolium bis(trifluoromethyl sulfonyl) amide) as a penetration enhancer in the formulation significantly enhanced the skin permeability of ovalbumin (OVA), a model antigen. It was also found that the IL-mediated S/O nanodispersion obtained high levels of OVA-specific serum IgG compared with both S/O nanodispersions without IL and PBS control. These findings clearly indicate that ILs – which are potentially attractive “green” and “designer” solvents – could serve as potential skin penetration enhancers in transcutaneous vaccination for hydrophilic macromols.
