The article was appeared in 《Chemosphere》. They have made some progress in their research.Computed Properties of C6H11ClN2 The article mentions the following:

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.

Today I want to share an article with you. The article is 《An efficient and stable magnetic nano-biocatalyst for biodiesel synthesis in recyclable ionic liquids》,you can find this article in 《Biomass Conversion and Biorefinery》. The following contents are mentioned:

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.

Nakhaei-Kohani, Reza;Ali Madani, Seyed;Mousavi, Seyed-Pezhman;Atashrouz, Saeid;Abedi, Ali;Hemmati-Sarapardeh, Abdolhossein;Mohaddespour, Ahmad published 《Machine learning assisted Structure-based models for predicting electrical conductivity of ionic liquids》 in 2022. The article was appeared in 《Journal of Molecular Liquids》. They have made some progress in their research.Recommanded Product: 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

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. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

Biodegradable films prepared from cellulose have been developed in recent years. In this work, six kinds of wood cellulose films (WCFs) were successfully prepared using wood cellulose as raw materials and six ionic liquids (ILs) as solvents. The structure and properties of WCFs produced using six imidazole-based and 1,5-diazabicyclo[4.3.o]non-5-ene (DBN)-based ILs were investigated systematically. It indicated that the WCFs produced from 1-ethyl-3-methylimidazolium di-Et phosphate ([Emim]DEP) had a maximum transmittance of 90.1% and tensile strength of 124.5 MPa, which were much higher than the counterparts to 26.2% and 42.0 MPa of the WCFs produced using DBN-based ILs. Moreover, the structure and properties of WCFs and ILs had a little change after five recycles. Based on that, we used the screened [Emim]DEP as a solvent to prepare a highly efficient UV-to-red light conversion cellulose film (LCF) by doping rare-earth light-converting particles, CaAlSiN₃:Eu²⁺ (CASN). Results showed that the LCF emitted red light at 640 nm and had excellent light conversion ability, which was conducive to photosynthesis.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Wu, Gaohong;Lv, Wenrong;Li, Xiaoxiao;Zhang, Wenming;Li, Zhanyu published 《Metal-Organic Framework Structure with Fe-Co-Se (MIL-88A/Fe-Co@Se) as a Cathode for Aluminum Batteries》 in 2021. The article was appeared in 《ACS Applied Materials & Interfaces》. They have made some progress in their research.Electric Literature of C6H11ClN2 The article mentions the following:

Rechargeable aluminum-ion batteries have received more and more attention because of their high theor. energy d., high safety, and reasonable price. The cathode material of aluminum batteries is one of the key bottlenecks that limits their development. Although there are many reports on aluminum battery cathode materials, many of these reports fail to simultaneously solve the poor cycling stability and low specific capacity of aluminum batteries. Therefore, we formed YSNT@Se hybrids by compounding the MOFs-MIL-88A@Fe-Co hydroxide yolk-shell nanotubes (YSNTs) with selenium for the first time. It was finally determined that the FeSe₂ in YSNT@Se is the main redox reaction participant during charging/discharging. In the charge/discharge of YSNT@Se 500°C, it achieved a first cycle discharge specific capacity of 292.21 mA h g^-1. After 500 cycles, the discharge capacity was 233.34 mA h g^-1 and the capacity retention rate reached 79.85%. This result proves that the redox process is highly reversible at the same time. This work makes it possible for aluminum batteries to have a high cycling performance and a high capacity and broadens the research direction of cathode materials for aluminum batteries. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

The article was appeared in 《Crystals》. 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:

Novel adsorbents for methane and ethane based on HKUST-1 metal-organic framework were synthesized by microwave (MW) assisted technique using ionic liquids (ILs) as synthesis media. It was found that the MW synthesis time remarkably impacts both the product yield and the physico-chem. characteristics of the produced HKUST-1 material. The crystalline phase purity, crystallite size/dispersion and textural properties of the synthesized HKUST-1 matrixes determine their performance in methane and ethane adsorption. Therefore, the HKUST-1 material produced in MW fields for 3 min only shows the highest phase purity and the largest surface area (BET) and porosity, along with a rather small crystallite size (below ∼300 nm), demonstrating high methane and ethane adsorption capacity in the pressure range 1-30 atm. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Liu, Chenyi;Ling, Yijie;Wang, Zhennan;Zheng, Weizhong;Sun, Weizhen;Zhao, Ling published 《Unveiling the microenvironments between ionic liquids and methanol for alcoholysis of poly(ethylene terephthalate)》. The research results were published in《Chemical Engineering Science》 in 2022.Synthetic Route of C6H11ClN2 The article conveys some information:

Ionic liquids (ILs) have proved to be efficient catalysts for the alcoholysis of poly(ethylene terephthalate) (PET). However, the in-depth understanding about the alcoholysis of PET at a mol. level remains scarce. Herein, the microstructures and dynamics of ILs/methanol systems with and without PET oligomer were investigated using mol. dynamics (MD) simulations. A better miscibility between [OAc]-containing ILs and methanol is observed There exist hydrogen-bonding networks between cation, anion, and methanol, in which the cation serves as a donor and methanol as an acceptor, while the anion/methanol hydrogen-bonding interaction follows the opposite donor-acceptor relationship. In ILs/methanol/PET ternary systems, the hydroxyl groups of [Cho] cations display a more significant interaction with carbonyl groups of PET oligomer than [Emim] cations. In addition, PET oligomer diffuses quite faster in [Cho][OAc] compared to [Emim][OAc]. The information obtained in this work is helpful to better understand the mechanism of the PET alcoholysis process.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

The research results were published in《ACS Applied Polymer Materials》 in 2022.Related Products of 65039-09-0 The article conveys some information:

Due to the excellent physio-chem. and mech. properties, ionic liquid epoxies (ILE) can serve as a perfect material for various technologies along with many other materials as a substrate. In this study, we employed mol. dynamics simulations to gain fundamental mol. insights about a conventional epoxy and an imidazolium-based ILE and how adhesion on crystalline cellulose surfaces is affected by crosslinking and the type of ionic liquid (IL) counter anions (e.g. [OAc], [Cl], and [TF₂N]) on thermo-mech. and moisture absorption of bulk ILE were further investigated. When comparing the ILE/cellulose systems vs. bulk ILE systems, the results indicate that the presence of a cellulose surface lowers the degree of crosslinking due to the adsorption of the hardener on its surface. Overall, the ILEs/cellulose exhibit a higher interfacial bonding energy than conventional epoxy/cellulose. Improved adhesion is significant for hydrophilic ILEs, which is likely attributed to hydrogen bonds formed between the cellulose and anion mols. This computational study provides mol.-level insights into the adsorption mechanism of ILE onto a crystalline cellulose surface, leading to the design of smart and multifunctional thermoset adhesives. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Frawley, Rachel P.;Germolec, Dori R.;Johnson, Victor J.;Gulledge, Travis;Manheng, Wimolnut;White, Kimber Jr.;Shockley, Keith R.;Harris, Shawn F.;Hooth, Michelle;Ryan, Kristen published 《Evaluation of skin sensitization induced by four ionic liquids》 in 2022. The article was appeared in 《Journal of Applied Toxicology》. They have made some progress in their research.Name: 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

Ionic liquids (ILs) are synthetic solvents used as replacements for volatile organic solvents. Human exposure occurs through dermal or oral routes. In rodents, several ILs were reported to induce dermal toxicity, irritation, and sensitization. Due to the potential for occupational exposure, and industrial use as nonvolatile solvents, 1-ethyl-3-methylimidazolium chloride (EMIM, 6.25% to 50% volume/volume), 1-butyl-3-methylimidazolium chloride (BMIM, 3.12% to 12.5% volume/volume), 1-butyl-1-methylpyrrolidinium chloride (BMPY, 0.825% to 6.25% volume/volume), and N-butylpyridinium chloride (NBuPY, 0.825% to 12.5% volume/volume) were nominated to the National Toxicol. Program and evaluated for skin sensitization. The test compound was applied to the ears of female BALB/c mice daily for 3 days in a primary irritancy (IRR)/local lymph node assay (LLNA). Sensitization was assessed in vitro in the direct peptide reactivity assay (DPRA), KeratinoSens assay, and human cell line activation test (h-CLAT). In the LLNA, the butylated ILs, BMIM, and BMPY were more potent than NBuPY (butylated) or EMIM (ethylated), which was neither an irritant nor a sensitizer. NBuPY induced skin irritation in vivo at ≥3.12% (p ≤ 0.01), and sensitization in vitro in the KeratinoSens assay and h-CLAT, but was neg. for sensitization in vivo and in the DPRA. Although SI3 was not achieved, dermal treatment with 12.5% BMIM or 6.25% BMPY increased (p ≤ 0.01) lymph node cell proliferation in the LLNA. In vitro, BMIM was pos. for sensitization in the h-CLAT, and BMPY was pos. in the h-CLAT and KeratinoSens assay; both were neg. in the DPRA. Integrated data analyses, weighted toward in vivo data, suggested that BMIM and BMPY may induce weak to mild sensitization. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Product Details of 65039-09-0In 2022, Zhang, Huan;Vicent-Luna, Jose Manuel;Tao, Shuxia;Calero, Sofia;Jimenez Rioboo, Rafael J.;Ferrer, Maria Luisa;del Monte, Francisco;Gutierrez, Maria Concepcion published 《Transitioning from Ionic Liquids to Deep Eutectic Solvents》. 《ACS Sustainable Chemistry & Engineering》published the findings. The article contains the following contents:

Ionic liquids (ILs) and deep eutectic solvents (DESs) have been lately the solvent of choice in number of processes because they offer a valid alternative to conventional solvents. Despite main interactions in ILs differ from those in DESs (e.g., electrostatic-type in the former and H-bond-type in the latter), these two neoteric solvents are more closely related that appeared and can be seen as the two sides, the face and the cross, of the same coin. Herein, we hypothesized about a way for transitioning from one to the other. In particular, we promoted the transition from 1-Ethyl-3-methylimidazolium chloride (EMIMCl) to EMIMCl·nAcOH-based DESs by the simple addition of stoichiometric amounts of acetic acid (AcOH) to EMIMCl. ¹H NMR spectroscopy and DSC confirmed the occurrence of such a transition. Mol. dynamics (MD) simulations revealed the Cl anion capability to fully accommodate up to 4 AcOH mols. (e.g., EMIMCl·AcOH, EMIMCl·2AcOH, EMIMCl·3AcOH, and EMIMCl·4AcOH) without sign of H-bond self-interactions between AcOH mols. These DESs also exhibited quite different solvent properties, with α and β Kamlet-and-Taft-parameters that differed from those of EMIMCl and 1-Ethyl-3-methylimidazolium acetate (EMIMOAc). Interestingly, excess molar volume and excess viscosity measurements as well as Brillouin spectroscopic experiments indicated that aqueous dilutions of EMIMCl·AcOH-based DESs deviated from ideality as consequence of the formation of HB between water mols. and the anion, and observed by ¹H NMR spectroscopy. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.
