The research results were published in《Fuel Processing Technology》 in 2022.Recommanded Product: 65039-09-0 The article conveys some information:

Synthesis of 5-hydroxymethylfurfural (HMF) from carbohydrate is one of vital step for bio-refinery development. In this work, a novel strategy was developed for catalytic conversion of fructose to HMF in 2-butanol. The inexpensive ionic liquids were used to adjust the acidity of biobased acid catalyst for enhancing the dehydration of fructose to HMF. The combination of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) with oxalic acid afforded an excellent HMF yield of 97.1% at 98.7% fructose conversion under mild conditions of 100°C and 60 min, owing to the enhanced dissociation ability of oxalic acid by [Bmim]Cl. A possible dissociation mechanism of oxalic acid induced by [Bmim]Cl was proposed based on control experiments and detailed analyses with NMR and FT-IR techniques. It involved that the [Bmim]Cl interacted with oxalic acid through hydrogen bond, which decreased the electron d. of oxygen atom on hydroxyl group and weakened the O-H bond, thus making the hydrogen in the O-H group to easily dissociate in the form of H⁺. Moreover, the reusability of oxalic acid and [Bmim]Cl was demonstrated, and both could be reused up to six times without significant loss in activity. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The article was appeared in 《New Journal of Chemistry》. They have made some progress in their research.Recommanded Product: 65039-09-0 The article mentions the following:

A series of nine tetrakis lanthanide β-diketonate complexes of the type [C₂mim][Ln(fod)₄] (C₂mim = 1-ethyl-3-methylimidazolium, fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate) were prepared, with yields above 80%, and their thermochem., photophys. and magnetic susceptibilities were evaluated. Thermochem. studies presented a rare and reversible conversion between two solid phases (polymorphism), characteristic of the [Ln(fod)₄]^– anion. Photophys. and magnetic studies revealed that Dy and Er presented the multifunctionality of being simultaneously SMMs and visible (Dy) or near infra-red (Er) emitters. The Nd, Ho and Tm analogs present characteristic emission bands in the NIR region (800-1200 nm), while Sm, Eu, Tb and Dy present emissions in the visible range. Magnetic susceptibility of Tb, Dy, Ho, Er and Tm salts were measured in the temperature range of 2-300 K, showing paramagnetic behavior, although with different regimes, with AC susceptibility measurements, at different frequencies in the range of 10-10 000 Hz, providing evidence of slow magnetic relaxation processes for Gd, Dy and Er analogs with SMM behavior. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

The author mentioned the following in the article:

The lack of knowledge on electrochem. reaction pathways for Al/S batteries prevents the development of practical approaches to mitigate the irreversibility and poor cycling performances of this appealing secondary battery system, which is, in theory, scalable, inexpensive, and energy-dense. Different from the Li/S system, Al/S batteries use ionic liquids (ILs) as electrolytes. The choice of the IL, i.e., whether the IL is based on a conventional EMImCl-based electrolyte or in a deep eutectic mixture of aluminum chloride with urea (or any of its derivatives), strongly affects the electrochem. energy-storage performance of the cell. To shed some light on the Al/S battery chem., here, we present the computational electrochem. research work to determine the most favorable reaction pathways and thermodynamically stable reaction intermediates. We also discuss the effect of the coordination of ionic species (originated from aluminum-containing deep eutectic electrolytes) with polysulfide intermediates, which lead to alterations in the reaction pathway and electrochem. behavior of the Al/S system. The spectroscopic signatures from various reaction intermediates are also reported and validated via comparison with exptl. observations.

The author mentioned the following in the article:

Hydro-elec. technol. has gathered much attention by the virtue of water as the energy source. However, the low energy d. of this technol. severely limits its practical use. Here, we demonstrate a PEDOT:PSS-based transpiration-driven electrokinetic power generator (p-TEPG) that enables the utilization of a wider variety of real-world water resources for maximizing energy generation efficiencies. In addition to the conventional elec. double layer on the material surface, the p-TEPG builds an addnl. p.d. in the polymer matrix by the selective penetration of cations into the matrix that contains sulfonate functional groups. p-TEPG exhibits 80-250% higher energy d. than carbon-based TEPG at the same resistance. Moreover, seawater produced enhanced volumetric energy/power densities (34.36 mJ cm^-3 and 44.70μW cm^-3) and areal energy/power densities (410μJ cm^-2 and 0.45μW cm^-2), resp., compared to DI water on a single p-TEPG device, which is sufficient to charge elec. energy storage systems and directly operate low-powered electronic.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Aluminum-metal batteries show great potential as next-generation energy storage due to their abundant resources and intrinsic safety. However, the crucial limitations of metallic Al anodes, such as dendrite and corrosion problems in conventional aluminum-metal batteries, remain challenging and elusive. Here, we report a novel electrodeposition strategy to prepare an optimized 3D Al anode on carbon cloth with an uniform deposition morphol., low local c.d., and mitigatory volume change. The sym. cells with the 3D Al anode show superior stable cycling (>450 h) and low-voltage hysteresis (∼170 mV) at 0.5 mA cm^-2. High reversibility (∼99.7%) is achieved for the Al plating/stripping. The graphite | | Al-4/CC full batteries show a long lifespan of 800 cycles with 54 mAh g^-1 capacity at a high c.d. of 1000 mA g^-1, benefiting from the high capacitive-controlled distribution.

Masri, Asiah Nusaibah;Sulaimon, Aliyu Adebayo published 《Amino acid-based ionic liquids as dual kinetic-thermodynamic methane hydrate inhibitor》 in 2022. The article was appeared in 《Journal of Molecular Liquids》. They have made some progress in their research.Related Products of 65039-09-0 The article mentions the following:

Three amino acid-based ionic liquids (AAILs) are synthesized to evaluate their performance as inhibitors. They are 1-ethyl-3-methyl-imidazolium-glutamate (EMIMGlu), 1-(3-cyanopropyl)-3-methyl-imidazolium-glutamate (CPMIMGlu) and 1-butyl-3-methyl-imidazolium-glutamate (BMIMGlu). The structures are clarified using NMR. Evaluation of their methane hydrate inhibitor performance is performed by micro-differential scanning calorimeter at 5-15 MPa. As a baseline, the hydrate dissociation in water is also evaluated. A standard correlation of methane hydrate dissociation in water is successfully developed with a low average absolute error. Addnl., the AAILs behave as both thermodn. (THI) and kinetic (KHI) hydrate inhibitors. They simultaneously shift the HLVE curve to a lower temperature and decelerate the hydrate formation by reducing the hydrate nucleation rate. EMIMGlu shows the highest THI performance by producing an average temperature shift of 1.14 K, followed by CPMIMGlu (0.91 K) and BMIMGlu (0.87 K). Furthermore, the addition of the nitrile group in CPMIMGlu IL has enhanced the kinetic inhibition process. The kinetic inhibition performance represented by the relative inhibition power (RIP) decreases in the trend of CPMIMGlu (1.31), EMIMGlu (1.30) and BMIMGlu (0.063). The mechanism of the inhibition is further studied by utilizing COSMO-RS software through σ-profile and σ-potential to understand the inhibition process at the mol. level. The exptl. results and computational studies reveal that AAILs behave as THI and KHI through the existence of four oxygen atoms in their anions and cyano group in the CPMIM cation. Thermodn. inhibition properties of AAILs are found to be influenced by the polarity of AAILs while the kinetic inhibition properties of AAILs are found to be influenced by the hydrogen-bonding acceptor value of the AAILs.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

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.

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.

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.
