Spiess, Alex;Brandt, Philipp;Schmitz, Alexa;Janiak, Christoph published 《Water sorption by ionic liquids: Evidence of a diffusion-controlled sorption process derived from the case study of [BMIm][OAc]》. The research results were published in《Journal of Molecular Liquids》 in 2022.Name: 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article conveys some information:

The hydrophilicity of ionic liquids (ILs) could be exploited as desiccants or in sorption-driven heat transformation, yet reports of water sorption isotherms of pure ionic liquids are still scarce. Here, water sorption studies for the six pure hydrophilic ionic liquids with 1-ethyl-3-methylimidazolium [EMIm]⁺ or 1-butyl-3-methylimidazolium [BMIm]⁺ cations and acetate [OAc]^–, formate [HCOO]^– or lactate [Lac]^– anions show a steady and high water uptake with a small hysteresis between absorption and desorption over the relative pressure range of p/p₀ = 0 – 0.9 for the first time. Repeated static volumetric sorption measurements with different amounts or different surface area of the example IL [BMIm][OAc] reveal a slow and strongly diffusion-driven sorption process stemming from the absorption of surface-adsorbed water into the bulk IL. Extrapolation of the water uptake to very small IL amounts with negligible kinetic hindrance gives an equilibrium water uptake capacity of over 2100 mg/g(IL) at p/p₀ = 0.9. Gravimetric control experiments at a relative humidity of 75.5% confirm the time-dependence with the IL surface area at the gas-liquid-interface and the amount of the IL to reach the equilibrium uptake of 1040 mg/g at p/p₀ = 0.75. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Today I want to share an article with you. The article is 《Aqueous-processable conducting polymer/ionic liquid solutions for highly conductive organic conductors》,you can find this article in 《Molecular Crystals and Liquid Crystals》. The following contents are mentioned:

Herein, we study how the introduction of secondary dopants, ionic liquids (ILs) into an aqueous-processable conducting polymer (CP), pe:PSS [poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate)] affects the PEDOT:PSS dispersion states in the solution, based on dynamic light-scattering anal. We also investigate the elec. characteristics of PEDOT:PSS/IL films that are processed from the composite blends with varied IL concentration As a result, we found that the addition of ILs causes growths of PEDOT:PSS dispersions, and there is a relationship between IL-induced dispersion growths and elec. conductivity enhancement. This work could provide a basis for achieving outstanding elec. performance from aqueous-processable CPs.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The article contains the following contents:

In search for new mol. entities as anti-TB agents, the benzimidazoquinazoline polyheterocyclic scaffolds I (R¹ = H, F, Cl, Br, Me, OMe; R² = H, Cl; R³ = H, Cl; R²R³ = -(CH)₄-; R⁴ = H, Me, Et, n-Pr, n-Bu) have been designed adopting the scaffold hopping strategy. Thirty-two compounds I have been synthesized through an improved tandem decarboxylative nucleophilic addition cyclocondensation reaction of o-phenylenediamines 1,2-(NH₂)₂-4- R²C₆H₂R³ with isatoic anhydrides II followed by further cyclocondensation of the intermediately formed 2-(o-aminoaryl)benzimidazoles III with trialkyl orthoformates R⁴C(OEt)₃. The resultant benzimidazoquinazolines I were evaluated in vitro for anti-TB activity against M. tuberculosis H37Rv (ATCC27294 strain). Fourteen compounds exhibiting MIC values in the range of 0.4-6.25μg/mL were subjected to cell viability test against RAW 264.7 cell lines and found to be non-toxic (<30% inhibition at 50μg/mL). The active compounds were further evaluated against INH resistant Mtb strains. The most active compound I (R¹ = Me; R² = R³ = H; R⁴ = n-Pr) [MIC (H37Rv) of 0.4μg/mL] and the compound I (R¹ = R² = R³ = H; R⁴ = n-Pr) [MIC (H37Rv) of 0.78μg/mL] were also found to be active against INH resistant Mtb strain with MIC values of 12.5 and 0.78μg/mL, resp.

In this paper, the influence of the side chain length of five ionic liquids (ILs): 1-methylimidazolium chloride ([C₀mim][Cl]), 1,3-dimethylimidazolium chloride ([C₁mim][Cl]), 1-ethyl-3-methylimidazolium chloride ([C₂mim][Cl]), 1-butyl-3-methylimidazolium chloride ([C₄mim][Cl]) and 1-hexyl-3-methylimidazolium chloride ([C₆mim][Cl]) on the interactions with ethylene glycol (EG) was studied. Based on the measurement of d. and elec. conductivity of the ionic liquid + EG mixture in the temperature range (278.15-313.15) K, the values of apparent molar volume, standard partial molar volumes, apparent molar volume at infinite dilution, Masson′s interaction coefficient, thermal expansion coefficient, limiting apparent molar expansibilities, Heppler′s coefficient, ion association constants, thermodn. parameters of ion-pair formation as well as diffusion coefficient was calculated Exptl. results were supported by mol. dynamic simulations. With the increase of the side chain length, from C0mim+ to C6mim+ cation, ion-dipole interactions on the solvation process decrease, and the influence of solvophobic solvation increases. Ionic liquids [C₀mim][Cl] and [C₁mim][Cl] show structure-breaker properties, [C₄mim][Cl] and [C6mim][Cl] structure-making properties in EG solutions, while [C₂mim][Cl] is borderline. The values of ion association constants in EG are higher than in water. The ion association process is spontaneous for all ionic liquids and entropy-driven.

Recommanded Product: 65039-09-0《Stretchable and self-healable double-network ionogel with strong adhesion and temperature tolerance for information encryption》 was published in 2022. The authors were Qiu, Zengfeng;Wang, Xiaolin;Wang, Tiantian;Zhao, Xiangjie;Zhang, Jingyue;Xu, Chao;Xu, Jiaheng;Yin, Hongzong, and the article was included in《Journal of Molecular Liquids》. The author mentioned the following in the article:

Recently, hydrogels with adjustable mech. properties have been developed for information security applications. However, the defects such as easy drying and inferior resistance to extreme temperatures limit their extended applications. Herein, a fluorescent double-network ionogel doped with imidazole-modified carbon quantum dots (CQDs) is constructed by the dynamic covalent crosslinking of chitosan with glutaraldehyde and chem. crosslinking of acrylamide in 1-ethyl-3-methylimidazolium chloride (EMIMCl). The ionogel exhibits high thermal stability and good resistance to high and low temperatures In addition, the as-prepared ionogel possesses good viscoelasticity with high elastic modulus (G’, ~105 Pa) and a viscosity of ~10⁴ Pa.s. Attributed to the excellent stretchability, durability and self-adhesion in a wide operating temperature range, the ionogel has been successfully constructed to a mechanochromic fluorescent device for the reversible encryption and decryption of the information. Dual stimuli of UV light and force are required to reveal the hidden information. Besides, the dynamic Schiff base bonds formed by amine groups of chitosan and aldehyde groups of glutaraldehyde allow the ionogel to quickly repair damages without external stimulation, prolonging its service life. Therefore, this work reports a new strategy for the preparation of soft materials for more secure information encryption by using high-performance ionogels.

The author mentioned the following in the article:

Ionic liquids (ILs) and deep eutectic solvents (DESs) are the two most widely used neoteric solvents. Recently, our group described how the simple addition of acetic acid (AcOH) to 1-Ethyl-3-methylimidazolium chloride (EMIMCl) could promote the transition from the original IL to an eutectic mixture of EMIMCl and AcOH. Herein, we studied how cellulose regeneration and EMIMCl recovery from EMIMCl solutions of cellulose could be benefited by the significant differences existing between EMIMCl- and EMIMCl·AcOH-based mixtures and the easy switching from one to the other. Finally, we also demonstrated that the transition could also be accomplished by addition of acetic anhydride and water so that the process could be eventually useful for the achievement of highly acetylated cellulose.

Liu, Qian;Zhang, Xianglan published 《Highly efficient separation of phenolic compounds from low-temperature coal tar by composite extractants with low viscosity》. The research results were published in《Journal of Molecular Liquids》 in 2022.Category: imidazoles-derivatives The article conveys some information:

Highly efficient separation of phenolic compounds from low-temperature coal tar (LTCT) is significant in the industry. In this work, composite extractants composed of imidazolium-based ionic liquids (ILs) and solvents were used to sep. phenolic compounds from model oil and LTCT. First, the COSMO-RS model was used to screen composite extractants that combined the infinite dilution thermodn. indexes and liquid-liquid equilibrium (LLE) calculations Meanwhile, the separation mechanism was analyzed by σ-profile and σ-potential. Then, the reliability of the COSMO-RS model was validated by LLE experiments and FT-IR. The viscosity of composite extractants with high separation performance was further determined Among the composite extractants, 1-ethyl-3-methyl-imidazolium hydrogen sulfate ([emim][HSO4])/ethylene glycol (EG) was selected as the most suitable extractant in the separation process. The m-cresol extraction efficiency and cumene entrainment were 98.1% and 8.3%, resp., at a [emim][HSO₄]:EG molar ratio of 1:2, a temperature of 25 °C, and a composite extractant: model oil mass ratio of 1:1. Moreover, the viscosity of [emim][HSO₄]:EG (1:2) was only 51.8 cP at 25 °C and decreased by 95.6% compared with pure [emim][HSO₄], which enhanced the mass transfer in the separation process. The [emim][HSO₄]:EG (1:2) could be regenerated and reused without significant reduction in separation performance. Finally, [emim][HSO₄]:EG (1:2) was applied to sep. phenolic compounds from LTCT with a phenol extraction efficiency of more than 99.9% and a neutral oil entrainment of 8.3%, providing a promising prospect for the separation of phenolic compounds1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Rocha, Ines L. D.;da Costa Lopes, Andre M.;Ventura, Sonia P. M.;Coutinho, Joao A. P. published 《Selective Separation of Vanillic Acid from Other Lignin-Derived Monomers Using Centrifugal Partition Chromatography: The Effect of pH》. The research results were published in《ACS Sustainable Chemistry & Engineering》 in 2022.Safety of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article conveys some information:

In this work, centrifugal partition chromatog. (CPC) assisted by a polyethylene glycol (PEG)/sodium polyacrylate (NaPA) aqueous biphasic system (ABS) was applied in the separation of five lignin-derived monomers (vanillin, vanillic acid, syringaldehyde, acetovanillone, and p-hydroxybenzaldehyde). The influence of the system pH (unbuffered, pH 5, and pH 12) and added electrolytes (inorganic salts or ionic liquids (ILs)) on the compound partition was initially evaluated. The obtained data revealed that ILs induced more adequate partition coefficients (K < 5) than inorganic salts (K > 5) to enable separation performance in CPC, while alk. conditions (pH 12) demonstrated a pos. impact on the partition of vanillic acid. CPC runs, with buffered ABS at pH 12, enabled a selective separation of vanillic acid from other lignin monomers. Under these conditions, a distinct interaction between the top (PEG-rich) and bottom (NaPA-rich) phases of the ABS with the double deprotonated form of vanillic acid is expected when compared to the remaining lignin monomers (single deprotonated). This is an impactful result that shows the pH to be a crucial factor in the separation of lignin monomer compounds by CPC, while only unbuffered systems have been previously studied in the literature. Finally, the recovery of vanillic acid up to 96% purity and further recycling of ABS phase-forming components were approached as a proof of concept through the combination of ultrafiltration and solid-phase extraction steps.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
