Based on artificial neural network (ANN), a new model is presented to estimate the heat capacity of pure ionic liquids A database for the heat capacity of ionic liquids created by extracting exptl. data from literature covering the period from 1971 to 2021 is reported. With the presented approach, heat capacity is calculated and evaluated by source data bank for 7059 data points of 143 ionic liquids The accuracies of new ANN model are evaluated by comparing with the most commonly used correlations in the literatures, and the results reveal that the proposed network provides more accurate results than other literature correlations considered in this work. The average absolute percentage deviation from the new model is only 1.14%. 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).

The Ionic Liquid-H₂O Interface: A New Platform for the Synthesis of Highly Crystalline and Molecular Sieving Covalent Organic Framework Membranes was written by Gao, Shuaiqi;Li, Zhiyong;Yang, Yingying;Wang, Zhenzhen;Wang, Yanlei;Luo, Shuangjiang;Yao, Kaisheng;Qiu, Jikuan;Wang, Huiyong;Cao, Li;Lai, Zhiping;Wang, Jianji. And the article was included in ACS Applied Materials & Interfaces in 2021.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

Covalent organic frameworks (COFs) are highly porous crystalline polymers with uniform pores and large surface areas. Combined with their modular design principle and excellent properties, COFs are an ideal candidate for separation membranes. Liquid-liquid interfacial polymerization is a well-known approach to synthesize membranes by reacting two monomers at the interface. However, volatile organic solvents are usually used, which may disturb the liquid-liquid interface and affect the COF membrane crystallinity due to solvent evaporation Simultaneously, the domain size of the organic solvent-water interface, named the reaction zone, can hardly be regulated, and the diffusion control of monomers for favorable crystallinity is only achieved in the water phase. These drawbacks may limit the widespread applications of liquid-liquid interfacial polymerization to synthesize diverse COF membranes with different functionalities. Here, we report a facile strategy to synthesize a series of imine-linked freestanding COF membranes with different thicknesses and morphologies at tunable ionic liquid (IL)-H₂O interfaces. Due to the H-bonding of the catalysts with amine monomers and the high viscosity of the ILs, the diffusion of the monomers was simultaneously controlled in water and in ILs. This resulted in the exceptionally high crystallinity of freestanding COF membranes with a Brunauer-Emmett-Teller (BET) surface area up to 4.3 times of that synthesized at a dichloromethane-H₂O interface. By varying the alkyl chain length of cations in the ILs, the interfacial region size and interfacial tension could be regulated to further improve the crystallinity of the COF membranes. As a result, the as-fabricated COF membranes exhibited ultrahigh permeance toward water and organic solvents and excellent selective rejection of dyes. 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 In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

From industrial black liquor to pure phenolic compounds: A combination of catalytic conversion with ionic liquids extraction was written by Garron, Anthony;Arquilliere, Philippe P.;Maksoud, Walid Al;Larabi, Cherif;Walter, Jean-Jacques;Santini, Catherine C.. And the article was included in Applied Catalysis, A: General in 2015.HPLC of Formula: 404001-48-5 This article mentions the following:

The conversion, in a sustainable way, of paper industry wastes such as black liquor into value-added mols. is still challenging. Herein, a direct catalytic conversion of black liquor into an aqueous solution has been achieved at moderate temperature and pressure (<250 掳C, 2 MPa). For this purpose, a multimetallic catalyst (Pd_0.5/Ni₁Cu₁-Mg₃₀AlO_x) has been synthesized and fully characterized. In presence of this material, a carbon-based conversion of 12 weight% has been obtained. The final liquid is composed of value-added phenolic compounds (i.e., guaiacol, creosol…) and the reaction can be afforded up to five cycles without deactivation. The green chem. concept consists of extracting these compounds without the use of volatile solvent and in safe operating conditions. For these reasons, the use of hydrophobic ionic liquids for the liquid-liquid extraction of these phenols has been investigated. The influences of the side chains of sym. and asym. imidazolium-NTf₂ as well as operational conditions (stirring rate and temperature) have been studied. As a result, [C₁C₆Im][NTf₂] has been found to be efficient in one-step total extraction phenolic components contained in the solution issued from the catalytic conversion of black liquor. This study showed that the catalytic hydropyrolysis of black liquor could be considered as an alternative source of phenolic compounds to conventional fossil resources.

Small-angle neutron scattering from mixtures of long- and short-chain 3-alkyl-1-methyl imidazolium bistriflimides was written by Cabry, Christopher P.;D’Andrea, Lucia;Elstone, Naomi S.;Kirchhecker, Sarah;Riccobono, Alessio;Khazal, Iman;Li, Peixun;Rogers, Sarah E.;Bruce, Duncan W.;Slattery, John M.. And the article was included in Physical Chemistry Chemical Physics in 2022.Category: imidazoles-derivatives This article mentions the following:

The preparation of mixtures of ionic liquids (ILs) represents an attractive strategy to tune their properties, an important aspect of which is to understand how the structure of the bulk varies with composition In this study, small-angle neutron scattering (SANS) was used to probe mixtures of methylimidazolium-based ionic liquids [C_nmim][Tf₂N] with [C₂mim][Tf₂N] (n = 4, 6, 8 and 10) and of [C_mmim][Tf₂N] with [C₁₂mim][Tf₂N] (m = 2, 4, 6 and 8). Mixtures were prepared in both contrasts, which is to say that one component would be fully hydrogenated while the other was fully deuterated, and vice versa. Data were fitted using a range of appropriate models, of which the Teubner-Strey model provided most useful information and the pure materials showed a nascent Polar Non-polar Peak (PNPP) for n = 6, which became more evident as n increased. In the mixtures [C_nmim]_x[C₂mim]_1-x[Tf₂N], the PNPP was evident for n = 10 and 8, nascent for n = 6 and absent for n = 4, with percolation showing a very strong dependence on the chain length of the added IL, [C_nmim][Tf₂N]. In contrast, while the ability of [C₁₂mim][Tf₂N] to form percolated structures was damped when mixed with [C_mmim][Tf₂N], as m increased from 2 to 6, this effect was less strong. However, data obtained for mixtures of [C₁₂mim][Tf₂N] and [C₈mim][Tf₂N], both of which percolate as pure materials, did not fit easily in any of the models applied to the previous systems and gave results that depended on the contrast used. Complementary small-angle X-ray scattering (SAXS) data, however, showed the expected evolution and behavior of the PNPP, COP and CP, revealing that the unexpected observations were due to an adventitious matching out of isotopic contrasts. As well as revealing details of the structures of these IL mixtures, the results also point to complementary strategies for generating bulk percolated structures as a function of cation chain length.

S. S.;Rebelo, Luis Paulo N.. And the article was included in Materials Chemistry and Physics in 2015.HPLC of Formula: 404001-48-5 This article mentions the following:

A hybrid organic-inorganic material composed of barium sulfate (BaSO₄) crystals embedded within a hydrophobic ionic liquid (ILs) matrix was synthesized. The contact between the inorganic solid and the organic coating is created by chem. interactions between the crystal surface and the ionic liquid The material exhibits higher affinity to lipophilic media than the nonmodified BaSO₄. Increased hydrophobicity is a property often sought for inorganic particles to be applied in nonpolar formulations. Immobilization of water-immiscible ILs on a hydrophilic solid carrier enables their application in aqueous solutions and the creation of appreciable hydrophobic-IL/water interfaces on the dispersion of solid-like material in aqueous media.

Hierarchically Crosslinked Gels Containing Hydrophobic Ionic Liquids towards Reliable Sensing Applications was written by Chen, Xia-Chao;Sun, Pei-Ru;Liu, Hong-Liang. And the article was included in Chinese Journal of Polymer Science in 2020.Formula: C18H31F6N3O4S2 This article mentions the following:

Human skin can function steadily regardless of surrounding circumstances (dry or wet), while it is still a challenge for artificial ionic skins, which tend to release solvents in dry air and leach electrolytes in wetted state. Herein, a series of hierarchically crosslinked ionogels containing hydrophobic ionic liquids (ILs) is fabricated by combining a crystalline fluorinated copolymer with hydrophobic ILs. With a reasonable combination of nonvolatility, transparency, stretchablility, and sensitivity, such ionogels can work as reliable sensors for real-time monitoring human motions and operate steadily in complex environments as human skin does, which can contribute to the development of durable sensing devices with a simple design.

Insights into the interplay between molecular structure and diffusional motion in 1-alkyl-3-methylimidazolium ionic liquids: a combined PFG NMR and X-ray scattering study was written by Martinelli, A.;Marechal, M.;Oestlund, A.;Cambedouzou, J.. And the article was included in Physical Chemistry Chemical Physics in 2013.Category: imidazoles-derivatives This article mentions the following:

We report on how the local structure and the diffusional motion change upon increasing the alkyl chain length in 1-alkyl-3-methylimidazolium cation ionic liquids This study has been performed by combining pulsed field gradient (PFG) NMR spectroscopy and small angle X-ray scattering (SAXS) experiments The cationic side chain length varies from Et (n = 2) to hexadodecyl (n = 16), while the anion is always bis(trifluoromethanesulfonyl)imide (TFSI). We find that the self-diffusivity of the individual ionic species is correlated to the local structure in the corresponding ionic liquid, namely the nano-segregation into polar and non-polar domains. In agreement with previous results, we observe that for relatively short alkyl chains the cations diffuse faster than the anions; however we also note that this difference becomes less evident for longer alkyl chains and a cross-over is identified at n 鈮?8 with the anions diffusing faster than the cations. Our results indicate that this controversial behavior can be rationalized in terms of different types of cation-cation and anion-anion orderings, as revealed by a detailed anal. of the correlation lengths and their dispersion curves obtained from SAXS data. We also discuss the validity of the Stokes-Einstein relation for these ionic liquids and the evolution of the extrapolated cationic radius that was found to depend non-strictly linearly on n, in agreement with the cation-cation correlation lengths.

A simple group contribution correlation for the prediction of ionic liquid heat capacities at different temperatures was written by Ahmadi, Alireza;Haghbakhsh, Reza;Raeissi, Sona;Hemmati, Vahid. And the article was included in Fluid Phase Equilibria in 2015.Category: imidazoles-derivatives This article mentions the following:

The heat capacities of pure ionic liquids (ILs) are among the thermophys. properties that are required for certain engineering calculations and designs. In this study, a simple correlation is presented for the prediction of the heat capacities of pure ionic liquids This correlation is a temperature-dependent relation that uses temperature, mol. weight and the number of atoms (such as carbon, hydrogen, oxygen, nitrogen, etc.) in the structure of the IL as input parameters. A dataset of approx. 128 different ILs, consisting of 4822 data points, was used to develop and validate this general correlation, covering a temperature range from 190 to 663 K. Nearly three-quarters of the data were used for optimization and a quarter for validation. The resulting correlation gives good estimations for heat capacities, while having a number of advantages over previous literatures methods. These advantages include (a) being very simple; (b) not requiring any exptl. data as input parameters; (c) being more global than previous literature models by having been constructed over a larger databank of ionic liquids; (d) being accurate. The average absolute relative deviation (AARD%) was calculated to be 5.8% for the optimization dataset, and 5.6% for the validation dataset. This is smaller than what is obtained for the literature at.-contribution methods proposed by Farahani et al. and Sattari et al., with AARD% values of 14.2% and 6.6%, resp., based on the validation dataset of this study.

Selection of low-toxic and highly efficient ionic liquids for the separation of palladium and platinum in acidic solution, and prediction of the metal affinity of ionic liquids was written by Lim, Che-Ryong;Choi, Jong-Won;Yun, Yeoung-Sang;Cho, Chul-Woong. And the article was included in Separation and Purification Technology in 2021.Recommanded Product: 404001-48-5 This article mentions the following:

Separation studies were conducted to sep. palladium (Pd) or platinum (Pt) from acidic solutions using 15 hydrophobic ionic liquids (ILs) capable of forming a binary phase with acidic aqueous solution This study considered two cases. The first was to find high-efficient ILs capable of separating metals from a single solution, and the second was to find ILs capable of selectively separating Pt from an acidic mixture solution of Pd and Pt. In addition, we also considered toxic effect of ILs for greener separation process. For this studies, we exptl. examined the separation efficiencies of the ILs, and discuss the properties with their toxicities, theor. predicted by previously presented toxicity prediction model, were compared. The results revealed that the extraction efficiency of ILs for Pd and Pt from acidic solutions depends on the types of IL and metal concentration In the separation study on Pd in a single metal solution, trihexyltetradecylphosphonium bromide [P6,6,6,14]Br and trioctylmethylammonium chloride [N8,8,8,1]Cl efficiently separates Pd from acidic solutions, while the separation on Pt in its single metal solution, 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM1-1Bz][(CF₃SO₂)₂N], 1-methyl-3-dodecylimidazolim bis(trifluoromethylsulfonyl)imide [IM12][(CF₃SO₂)₂N], 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM16][(CF₃SO₂)₂N], [P6,6,6,14]Br and [N8,8,8,1]Cl led to high efficiencies. Moreover, in the study to selectively sep. Pt from a mixed solution of Pd and Pt, [IM1-1Bz][(CF₃SO₂)₂N] and [IM16][(CF₃SO₂)₂N] have significant separation efficiency. When comparing the efficiencies and toxicities of the two ILs, [IM1-1Bz][(CF₃SO₂)₂N] is more efficient, but it is more toxic than [IM16][(CF₃SO₂)₂N]. Thus, for sustainable development, [IM16][(CF₃SO₂)₂N] can be considered as a better option. Moreover, in order to understand the partitioning mechanisms of ILs we developed quant. structure-activity relationship models with R² values greater than 0.91.
