Self-segregated nano-structure in room temperature ionic liquids was written by Pontoni, Diego;Haddad, Julia;Di Michiel, Marco;Deutsch, Moshe. And the article was included in Soft Matter in 2017.Category: imidazoles-derivatives This article mentions the following:

The nano-segregated bulk structure, and its evolution with the cation’s alkyl length n, are studied by X-ray scattering for an unprecedentedly broad homologous series of a model room-temperature ionic liquid, [C_nMIM][NTf₂] (n = 4-22). A tri-periodic local structure is found, with the lateral periodicities, d_II and d_III independent of n, and a longitudinal one, d_I, linearly increasing with n. The results are consistent with a local structure comprising alternating layers of polar head-groups and apolar, interdigitated, partly overlapping, cations’ alkyl tails, of an average macroscopic mass d. close to that of liquid alkanes. A slope decrease in the linear d_I(n) suggests a change from a lower to a higher rate of increase with n of chain overlap for n â‰?12. The order decay lengths of the layering, and of the lateral chain packing, increase with n, as expected from the increasing van der Waals interaction’s domination of the structure. The head-groups lateral packing decay length decreases with n, due to increasing frustration between the longer lateral periodicity preferred by the head-groups, and the shorter lateral periodicity preferred by the chains. A comparison of the bulk and surface structures highlights the surface’s ordering effect, which, however, does not induce here a surface phase different from the bulk, as it does in liquid crystals and liquid alkanes. 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).

Nonchromatographic Speciation of Selenium in Edible Oils Using Dispersive Liquid-Liquid Microextraction and Electrothermal Atomic Absorption Spectrometry was written by Lopez-Garcia, Ignacio;Vicente-Martinez, Yesica;Hernandez-Cordoba, Manuel. And the article was included in Journal of Agricultural and Food Chemistry in 2013.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

A methodol. for the nonchromatog. separation of the main selenium species present in edible oils is presented. Dispersive liquid-liquid microextraction is used to extract inorganic selenium (iSe), seleno-L-cystine (SeCys₂), seleno-L-methionine (SeMet), and selenocystamine (SeCM) into a slightly acidic aqueous medium. The selenium total (tSe) content is measured in the extracts by electrothermal at. absorption spectrometry. By repeating the microextraction stage using an ionic liquid instead of water, the sum of SeCys₂, SeMet, and SeCM is obtained and iSe is calculated by difference. The detection limit is 0.03 ng of Se per g of oil. The fractionation of the edible oils by solid phase extraction followed by dispersive liquid-liquid extraction and at. absorption measurement also permits speciation of iSe to be carried out. Data for tSe and iSe levels of 15 samples of different origin are given. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

Structural effect on the vapor-liquid equilibrium of toluene-ionic liquid systems was written by Yu, Gangqiang;Jiang, Yifan;Cheng, Jun;Lei, Zhigang. And the article was included in Chemical Engineering Science in 2019.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The vapor-liquid equilibrium (VLE) of toluene-ionic liquid (IL) from short- to long-chain imidazolium-based ILs (i.e., [C₄MIM]⁺, [C₈MIM]⁺, [C₁₀MIM]⁺, and [C₁₂MIM]⁺) with various anions (i.e., [BF₄]^–, [PF₆]^–, and [Tf₂N]^–) was first measured under wide concentration and temperature ranges. These thermodn. data are of great significance for an in-depth understanding with respect to capturing condensable gases with ILs. The UNIFAC-Lei model was applied to describe the VLE and successfully extended from short- to long-chain imidazolium-based ILs. For the ILs with relatively short alkyl side-chains on cations (e.g., [C₄MIM]⁺ and [C₈MIM]⁺), the vapor pressure depends on the types of both anions and cations, while for the ILs with long alkyl side chains on cations (e.g., [C₁₀MIM]⁺ and [C₁₂MIM]⁺), the vapor pressure is mainly dependent on the type of cations. Moreover, the COSMO-RS model and quantum chem. calculations were used together to provide microscopic insights into the effect of IL structures on the VLE of toluene-IL systems.

Cation molecular structure affects mobility and transport of electrolytes in porous carbons was written by Osti, Naresh C.;Dyatkin, Boris;Gallegos, Alejandro;Voneshen, David;Keum, Jong K.;Littrell, Ken;Zhang, Pengfei;Dai, Sheng;Wu, Jianzhong;Gogotsi, Yury;Mamontov, Eugene.

We examined the electrosorption and ion dynamics of imidazolium-based room temperature ionic liquids (RTILs) having short (3-carbon, C3mim+) and long (12-carbon, C12mim+) cations, i.e., 1-propyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (C3mimTFSI) and 1-dodecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (C12mimTFSI), confined in ordered mesoporous carbon (OMC) and analyzed the influence of the cation alkyl chain length on the ion dynamics and the capacitive behavior using electrochem. measurements together with quasi-elastic neutron scattering (QENS) observations and classical d. functional theory (cDFT) computations. Electrochem. tests highlighted the significant influence of specific applied potentials on accumulated charge storage densities and on the limits of saturation of larger electrolytes in the pores. Computational analyses corroborated these findings and predicted a 16% increase in the capacitance of the smaller-cation electrolyte under high applied potentials. However, QENS experiments revealed a behavior of decoupling of alkyl chain dynamics from the ring in electrolytes with larger ions. cDFT calculations identified d. spikes for C12mim+ away from the pore walls to further corroborate this unique behavior. Our insights into chain length-dependent dynamics and electrosorption in complex electrolyte-electrode systems deepen fundamental understanding of confined RTIL electrolyte behavior in the porous carbon electrodes.

Phase Equilibrium Investigation on 2-Phenylethanol in Binary and Ternary Systems: Influence of High Pressure on Density and Solid-Liquid Phase Equilibrium was written by Domanska, Urszula;Krolikowski, Marek;Wlazlo, Michal;Wieckowski, Mikolaj. And the article was included in Journal of Physical Chemistry B in 2018.Formula: C18H31F6N3O4S2 This article mentions the following:

Ionic liquids (ILs) are important new solvents proposed for applications in different separation processes. Herein, an idea of possible use of high pressure in a general strategy of production of 2-phenylethanol (PEA) is discussed. In this work, we present the influence of pressure on the d. in binary systems of 1-hexyl-1-methylpyrrolidynium bis{(trifluoromethyl)sulfonyl}imide, [HMPYR][NTf₂], or 1-dodecyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [DoMIM][NTf₂] + PEA in a wide range of temperatures (298.15-348.15 K) and pressures (0.1-40 MPa). The densities at ambient and high pressures are measured to present the physicochem. properties of the ILs used in the process of separation of PEA from aqueous phase. The Tait equation was used for the correlation of d. of one-component and two-component systems as a function of mole fraction, temperature, and pressure. The influence of pressure is not significant. These systems exhibit mainly neg. molar excess volumes, V^E. The solid-liquid phase equilibrium (SLE) of [DoMIM][NTf₂] in PEA at atm. pressure was measured and compared to the SLE high-pressure results. Addnl., the ternary liquid-liquid phase equilibrium (LLE) at ambient pressure in the {[DoMIM][NTf₂] (1) + PEA (2) + water (3)} at temperature T = 308.15 K was investigated. The solubility of water in the [DoMIM][NTf₂] is quite high in comparison with that measured by us earlier for ILs (x₃ = 0.403) at T = 308.15 K, which results in not very successful average selectivity of extraction of PEA from the aqueous phase. The [DoMIM][NTf₂] has shown strong interaction with PEA without the immiscibility region. The ternary system revealed Treybal’s type phase equilibrium in which two partially miscible binaries ([DoMIM][NTf₂] + water) and (PEA + water) exist. From the results of LLE in the ternary system, the selectivity and the solute distribution ratio of separation of water/PEA were calculated and compared to the results obtained for the ILs measured earlier by us. The popular NRTL model was used to correlate the exptl. tie-lines in ternary LLE. These results may help in a new technol. project of “in situ” extraction of PEA from aqueous phase during the biosynthesis. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Formula: C18H31F6N3O4S2).

An analysis of radical diffusion in ionic liquids in terms of free volume theory was written by Merunka, Dalibor;Peric, Miroslav. And the article was included in Journal of Chemical Physics in 2020.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The Heisenberg spin exchange-dipole-dipole separation method was used to measure the translational diffusion coefficients of the ¹⁴N-labeled perdeuterated 2,2,6,6-tetramethyl-4-oxopiperidine-1-oxyl (¹⁴N-pDTEMPONE) nitroxide spin probe as a function of temperature in two methylimidazolium ionic liquid series, one based on the tetrafluoroborate (BF₄) anion and another one on the bis(trifluoromethane)sulfonimide (TFSI, Tf₂N) anion. The obtained translational diffusion coefficients of ¹⁴N-pDTEMPONE were analyzed in terms of the Cohen-Turnbull free volume theory. It was found that the Cohen-Turnbull theory describes exceptionally well the translational diffusion of ¹⁴N-pDTEMPONE in all the ionic liquids in the measured temperature range. In addition, the Cohen-Turnbull theory was applied to the viscosity and self-diffusion coefficients of the cation and anion-taken from literature-in the same ionic liquids The critical free volume for the self-diffusion of the cation and anion in a given ionic liquid is the same, which suggests that the diffusion of each ionic pair is coordinated. The critical free volumes for the ¹⁴N-pDTEMPONE diffusion, self-diffusion, and viscosity for a given cation were about 20% greater in the TFSI based ionic liquids than in the BF₄ based ionic liquids It appears that the ratio of the critical free volumes for a given cation between the two series correlates with the ratio of their densities.

Imidazolium ionic liquids as toluene vapor absorbent were evaluated by a mol. screening method based on the COSMO-SAC model. A σ-map was established for hundred common imidazolium ionic liquids composed of N,N′-dialkylimidazolium cation and an anion. Absorption potential of ionic liquids to toluene vapor at 303.15 K was calculated from the σ-map and was used as thermodn. evaluation criterion to screen absorbents. Exptl. measurements on saturated absorption of toluene vapor in six ionic liquids showed consistent results with these of mol. screening, which verified reliability of this mol. screening method.

A priori prediction of complex liquid-liquid-liquid equilibria in organic systems using a continuum solvation model was written by Bairagya, Priyotosh;Kundu, Debashis;Banerjee, Tamal. And the article was included in Physical Chemistry Chemical Physics in 2020.Application of 404001-48-5 This article mentions the following:

Liquid-liquid-liquid equilibrium (LLLE) is usually observed in many industrial processes primarily linked to enhanced oil recovery techniques. However their measurements are complex and so are their computations. An inherently predictive tool is often useful for elucidating their distribution ratios and phase compositions In the present work, the phase behavior of nine ternary and two quaternary LLLE systems were predicted employing the quantum chem. based COnductor like Screening MOdel-Segment Activity Coefficient (COSMO-SAC) model. The methodol. namely, Rachford-Rice LLLE (RRL3E) algorithm and Henley-Rosen LLLE (HRL3E) algorithm were used to predict the triphasic compositions in each system. In the RRL3E approach, the triphasic systems were assumed into two co-existing biphasic liquid-liquid equilibrium systems, whereas in the HRL3E approach, all three phases were considered to be in equilibrium with each other simultaneously. Apart from predicting the local compositions, the HRL3E algorithm was also used to predict the individual phase splits and phase fractions of the LLLE region. Average overall root mean square deviation (rmsd (%)) values considering all 42 datasets and corresponding to 414 data points were recorded as 4.65% and 4.83% using the RRL3E and HRL3E algorithms resp. Further, the RRL3E algorithm was extended to correlate the LLLE data for all systems using the Genetic Algorithm (GA) based NRTL (GA-NRTL) and UNIQUAC (GA-UNIQUAC) models.

Correlation and prediction of ionic liquid viscosity using Valderrama-Patel-Teja cubic equation of state and the geometric similitude concept. Part I: Pure ionic liquids was written by Valderrama, Jose O.;Cardona, Luis F.;Rojas, Roberto E.. And the article was included in Fluid Phase Equilibria in 2019.Reference of 404001-48-5 This article mentions the following:

A generalized viscosity equation of state including a single adjustable parameter for correlating and estimating the viscosity of ionic liquids at different temperatures and pressures is proposed. The similar shape and form of the curves (isotherms and saturation lines) observed in a d.-pressure-temperature plot and in a viscosity-pressure-temperature plot (ρTP and μTP plots), known as geometrical similitude, is the basis of the proposed model. Viscosity data available in the literature has been gathered, analyzed, and selected to finally construct a database of consistent data to obtain a general model. The generalized equation of state model includes a number of parameters that are determined by fitting the model using the selected exptl. viscosity data of different types of ionic liquids In total, 3857 viscosity data for 187 ionic liquids in the temperature range of 253-573 K and pressures from 1.0 up to 1500 bar have been considered. The generalized viscosity model has been compared with other existing approaches and results show that the new viscosity cubic equation of state model provides accurate and consistent results taking in account the simplicity of the generalized expressions, which contains only one adjustable parameter for each ionic liquid 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).
