This study reports a novel magnetic nanoadsorbent prepared from magnetite (Fe₃O₄) as the magnetic core, activated carbon from coal fly ash and an ionic liquid (1-methyl-3-ethylimidazolium chloride). The magnetic nanoadsorbent was synthesized via co-precipitation and characterized by FTIR, XRD, TEM, EDS and BET surface area anal. Batch adsorption studies on cadmium (Cd²⁺) and lead (Pb²⁺) solutions such as effect of pH, contact time and adsorbent dosage were carried out. The data was analyzed using the Langmuir and Freundlich models. The results revealed that the optimal adsorption conditions for both metal ions on synthesized nanoadsorbent were pH 6, 200 min, adsorbent dosage of 1.5 g/L, initial ion concentration of 10 ppm and a temperature of 25°C. The data obtained in the adsorption of Cd²⁺ and Pb²⁺ best fitted the Freundlich isotherm, with R2 values of 0.998 and 0.995, resp. Thermodn. and kinetic studies suggested that adsorption of both metal ions on the IL-AC-Fe₃O₄ nanocomposite followed the pseudo first order model. The synthesized nanoadsorbent (IL-AC-Fe₃O₄) exhibits good adsorption properties and has great potential in a water treatment technol. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Category: imidazoles-derivativesIn 2022, Yahya, M. S.;Lau, E. V. published 《Dominance of hydrophobic attraction in attachment of microbubbles and Graphene oxide (GO)》. 《Chemical Engineering Science》published the findings. The article contains the following contents:

This paper presents the synthesis of GO-coated microbubbles which would be useful for environmental remediation and enhanced heat transfer applications. The mechanism of microbubble-GO attachment including electrostatic interactions, hydrophobic attraction, contact angle and Gibb’s free energy were determined Preliminary experiments indicated that water alone is not favorable, which thus necessitated the use of a bridging surfactant. The optimum attachment between microbubbles and GO occurred at the GO’s isoelec. point (IEP) in the ionic liquid as surfactant (IL), in which the IL concentration allowed GO to achieve maximum hydrophobicity. Therefore, it is inferred that hydrophobic attraction is the dominant force for microbubble-GO attachment with minor contributions from electrostatic interactions. Further studies showed that the longest carbon chain length IL, i.e. 1-Dodecyl-3-methylimidazolium chloride ([C₁₂mim]Cl) produced the most conducive environment for microbubble-GO attachment at its IEP concentration of 350 ppm.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Ionic liquids (ILs) have attracted a great deal of attention as vital compounds that are widely used in various industries, such as the chem. and petroleum industries. Therefore, determining the properties of ionic liquids, such as elec. conductivity (EC), is an important issue. In this study, four different machine learning approaches including K-nearest neighbors (KNN), extreme gradient boosting (XGB), adaptive boosting-decision tree (Ada-DT), and adaptive boosting-support vector regression (Ada-SVR) were established to predict EC of ILs based on two categories namely: (I) smart models based on ILs chem. structure and temperature, and (II) smart models based on ILs thermodn. properties and temperature For this purpose, 2625 laboratory data points corresponding to 225 ILs have been used. The results showed that based on Model (I), KNN model with root mean square error (RMSE) and coefficient of determination (R2) values of 0.1976 and 0.9935, resp., is the best model in predicting EC. Also, based on Model (II), the XGB model with RMSE and R2 values of 0.1447 and 0.9965, resp., is the most powerful and accurate model for estimating elec. conductivity Sensitivity anal. revealed that temperature and mol. weight have a direct and inverse effect on increasing the elec. conductivity of ILs, resp. The investigation of the effects of different chem. bonds (in the chem. structure of ionic liquids) on ILs EC showed that -CH2- and > N- substructures have the most neg. and pos. effect on EC, resp. Also, the proposed smart paradigms were capable of accurately predicting the effect cation alkyl chain length on elec. conductivity Based on the leverage technique assessment more than 95% of total data points are in a valid region which indicates that intelligent models are reliable. Consequently, the introduction of intelligent models based on the chem. structure of ILs, the much broader data bank, and the higher accuracy of the proposed models are among the innovations and advantages of this study compared to the previous researches. Findings of this study highlights that chem. structure-intelligence based approaches provide robust, reliable and accurate way to predict EC of ILs.

Abstract: The process of jatropha oil transesterification was studied for biodiesel production Rhizomucor miehei lipase (RML) immobilized on 3-aminopropyltriethoxysilane functionalized magnetic Fe₃O₄ was employed as a biocatalyst. The immobilized lipase was confirmed by scanning electron microcopy (SEM), Fourier transform IR spectra (FT-IR), thermogravimetric anal. (TGA), vibrating sample magnetometer (VSM), and confocal laser scanning microscopy (CLSM) techniques. The efficient biodiesel synthesis in ionic liquids using immobilized RML was demonstrated. Fifteen kinds of ionic liquids based on different alkyl chain lengths of the Me imidazolium cation ([C₂MIM], [C₄MIM], [C₈MIM], [C₁₂MIM], and [C₁₆MIM]) combined with [NTf₂], [N(CN)₂], [PF₆] or [BF₄] anions were assayed as reaction media for RML producing biodiesel. The highest synthetic activity of immobilized RML appeared in [BMIM][PF₆], which is more than five times higher than the free enzyme. The enzyme catalytic activity remained 60even after the magnetic nano-biocatalyst and ionic liquid had been reused 5 times in a 48-h reaction cycle. In addition, the immobilized enzyme exhibited excellent storage stability with almost no decrease in catalytic activity after storing at -20 °C for 98 days.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The present work focuses on the development of a new electrochem. platform based on CoMn2O4-rGO/1-ethyl-3-methylimidazolium chloride modified carbon paste electrode (CoMn2O4-rGO/IL/CPE) for electrochem. determination of pethidine in the presence of biol. species. For the first time, the electrooxidation mechanism of pethidine in presences of morphine and olanzapine is investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) technologies. The as-synthesized CoMn2O4-rGO nanocomposites are characterized by physicochem. measurements such as X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), Field emission SEM (FE-SEM), and Fourier transform IR (FT-IR). The obtained results illustrated synergistic interactions between rGO and CoMn2O4 structures. Also, to investigate the electrode charge-transfer resistances, electrochem. features of the resulting nanocomposites are studied via electrochem. impedance spectroscopy (EIS) anal. Based on the result, three segmented linear ranges are observed over the range 0.08-900μM and detection limit of 0.024μM. Over the 10.0-40.0μM ranges of pethidine in phosphate buffer solution (PBS-pH 7.0), suitable diffusion coefficient of 5.67 x 10-7 cm2 s-1 is evaluated by chronoamperometry technique (CHA). Finally, the CoMn2O4-rGO/IL/CPE with high sensitivity, selectivity and repeatability is successfully used for determination of pethidine in real sample and drug formulation.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

They have made some progress in their research.Application In Synthesis of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

In this study, liquid-liquid equilibrium data of an aqueous two-phase system (ATPS) composed of alcs. (ethanol, 1-propanol, or 2-propanol) and small-mol. organic compound (sodium citrate, sodium tartrate, sucrose, maltose, and lactose) was extensively investigated at 298.1 K ± 0.1 K. The binodal curves were summarized through the empirical nonlinear equations with the lowest standard deviation. The contents of alcs. and organic salts in ATPS were accurately determined by gas chromatog. and UV spectrophotometer. The phase-forming abilities of alcs. were ranked in the following order, 1-propanol > 2-propanol > ethanol, resp. The ATPS composed of saccharides was difficult to form two phases due to the high viscosity. The salting-out abilities of sodium citrate (C₆H₅Na₃O₇) were better than sodium tartrate. 1-propanol/ C₆H₅Na₃O₇ATPS had larger biphase areas, it was further applied to concentrate various ionic liquids including [C₂mim]BF₄, [C₄mim]BF₄, [C₄mim]Cl and [C₈mim]Cl. The results showed that alc./organic salt ATPS had a better extraction rate to imidazole-type ionic liquids Ionic liquids were mainly distributed in the top phase (alc.-rich phase).

Ren, Fei;Wang, Jinwei;Yu, Jinglin;Zhong, Cheng;Xie, Fengwei;Wang, Shujun published 《Green synthesis of acetylated maize starch in different imidazolium carboxylate and choline carboxylate ionic liquids》. The research results were published in《Carbohydrate Polymers》 in 2022.Recommanded Product: 65039-09-0 The article conveys some information:

This work demonstrates that acetylated maize starches (AMS) with varied degree of substitution (DS, 0.26-2.63) was synthesized in ionic liquids (ILs) (imidazolium chloride, imidazolium carboxylate and choline carboxylate) at 85°C without catalyst. The DS of AMS and reaction efficiency increased with decreasing alkyl chain length of cations or anions, while decreased as the choline cation replaced the imidazolium cation and the chloride anion replaced the acetate anion. The AMS synthesized in imidazolium-based ILs exhibited much higher hydrophobicity and thermal stability than the native starch. Rheol. properties of ILs and ATR-FTIR anal. of acetic anhydride/ILs mixtures indicated that a shorter alkyl side chain or the combination of an imidazolium cation and an acetate anion gave ILs lower viscosities and weaker interactions between acetic anhydride mols., which favored the acetylation of starch. These findings provide insights into the design of green processes to modify starch and the application of acetylated starch. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

COA of Formula: C6H11ClN2《Structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids》 was published in 2022. The authors were Huang, Liurong;Ding, Shuang;Chen, Tian;Wu, Ruike;Wang, Xinyu;Jia, Shifang, and the article was included in《Journal of Applied Polymer Science》. The author mentioned the following in the article:

This paper explores the structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids (ILs). Results show that the solubility of collagen was significantly influenced by the type and concentration of ILs. With the increase of IL concentration, a remarkable decrease in solubility of collagen was seen. Fluorescence spectra show that heat and IL pretreatments induced the exposure of chromophores. Changes in sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that subunits of collagen regenerated from most of the IL solvent systems were not destroyed. The functional properties of regenerated collagen were evaluated by gel strength, viscosity, water-binding capacity, and emulsifying capacity. Results show that all heat-assisted ILs pretreatments improved the gel strength and viscosity, and the highest gel strength and viscosity were both obtained in the collagen pretreated by heat-assisted [EMIM]Cl. Heat-assisted [BMIM]BF₄ pretreatment exhibited the lowest water-binding capacity. Heat-assisted [BDMIM]Cl pretreatment indicated superior effect on improving emulsifying capacity than other pretreatments due to its ability to break most of the hydrogen bonds in collagen mols., resulting in the formation of new re-aggregates with higher solubility and more hydrophobic groups. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Recently, an important focus of material research has been aimed at more sustainable smart materials with biodegradable, biocompatible properties such as those based on cellulose (Cell), made stimuli-responsive with the addition of multiwall carbon nanotubes (CNT). Formulated as fibers, such materials have potential applications in smart clothing and wearable’s in actuation or sensing function. In order to ensure maximum performance, an optimal driving voltage and regime must be chosen. In addition to the quant. effects, the actuation response also qual. and mechanistically changes, depending on the voltage range. The linear actuation measurements combined with cyclic voltammetry and square wave potential steps were performed in aqueous lithium bis(trifluoromethane)sulfonimide solution The Cell-CNT fiber actuation response properties were investigated at different potential ranges: 0.8-0.0 V, 0.8 V to – 0.3 V, 0.8 V to – 0.55 V and 0.65 V to – 0.6 V, observing a change in actuation direction between the ranges. Not just the potential range but also the driving frequency had an impact on the response, therefore, the selection of driving parameters is shown to be critical for controllable performance.
