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.

SDS of cas: 65039-09-0In 2022, Xie, Yanyan;Gao, Hongshuai;Zhang, Puyu;Qin, Congwen;Nie, Yi;Liu, Xue published 《Preparation of Degradable Wood Cellulose Films Using Ionic Liquids》. 《ACS Applied Polymer Materials》published the findings. The article contains the following contents:

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.

The authors were Xu, Mengyu;Wang, Chun-Hung;Terracciano, Anthony C.;Masunov, Artem E.;Vasu, Subith S., and the article was included in《Scientific Reports》. The author mentioned the following in the article:

Fentanyl is an anesthetic with a high bioavailability and is the leading cause of drug overdose death in the U. S. Fentanyl and its derivatives have a low LD and street drugs which contain such compounds may lead to death of the user and simultaneously pose hazards for first responders. Rapid identification methods of both known and emerging opioid fentanyl substances is crucial. In this effort, machine learning (ML) is applied in a systematic manner to identify fentanyl-related functional groups in such compounds based on their observed spectral properties. In our study, accurate IR (IR) spectra of common organic mols. which contain functional groups that are constituents of fentanyl is determined by investigating the structure-property relationship. The average accuracy rate of correctly identifying the functional groups of interest is 92.5% on our testing data. All the IR spectra of 632 organic mols. are from National Institute of Standards and Technol. (NIST) database as the training set and are assessed. Results from this work will provide Artificial Intelligence (AI) based tools and algorithms increased confidence, which serves as a basis to detect fentanyl and its derivatives The experimental procedure involved many compounds, such as 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .

Rahmani, Farzin;Pasquinelli, Melissa A. published 《Molecular Insights into the Interfacial Properties of Cellulose Surfaces with Varying Types of Ionic Liquid Epoxies》. 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.

Soheilmoghaddam, Farhad;Sharifzadeh, Ghorbanali;Adelnia, Hossein;Wahit, Mat Uzir published 《Development of Regenerated Cellulose/Citric Acid Films with Ionic Liquids》 in 2022. The article was appeared in 《Journal of Polymers and the Environment》. They have made some progress in their research.Category: imidazoles-derivatives The article mentions the following:

Nowadays, the importance of green and biodegradable plastics as viable substitutes for non-degradable petroleum-based materials is felt more than ever. Regenerated cellulose (RC) as a potential candidate suffers from poor processability and inferior properties, limiting its wide applications. In this study, it is demonstrated that citric acid (CA) enhances phys., mech., and thermal properties of RC films, due to RC-citric acid compatibility. 1-Ethyl-3-methylimidazolium chloride (EMIMCl) as a green ionic liquid was employed for the processing of RC. The optimum properties in terms of thermal stability, mech. strength, contact angle, water uptake, and oxygen permeability were achieved at 10 wt% of CA. However, further incorporation of CA adversely affected the film properties. This behavior was explained by the crosslinking and plasticizing effects of CA. Furthermore, in vitro cytotoxicity test demonstrated that RC/CA films are cytocompatible, suggesting the potential advantage of using these biopolymeric films for biomaterial and biol. applications.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.

Liu, Zhuo et al. published new progress in experiments with the help of cas: 65039-09-0

Liu, Zhuo;Cheng, Hanlin;Le, Qiujian;Chen, Rui;Li, Jianbo;Ouyang, Jianyong published 《Giant Thermoelectric Properties of Ionogels with Cationic Doping》. The research results were published in《Advanced Energy Materials》 in 2022.HPLC of Formula: 65039-09-0 The article conveys some information:

Although ionic thermoelec. (iTE) materials can have very high thermopower, it is of great significance to develop novel methods to further improve the ionic thermopower and figure of merit (ZTi). Here, significant improvement in the thermopower and thus the ZTi value of an ionogel by cationic doping, is reported. Doping sodium dicyanamide (Na:DCA) into the ionogels of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and 1-ethyl-3-methylimidazolium dicyanamide (EMIM:DCA) that is an ionic liquid can greatly enhance the thermopower. This is attributed to the interactions between the doped Na+ cations and DCA- anions, thereby increasing the difference in the mobilities of EMIM+ cations and DCA- anions. Moreover, through the combination with the solid networks engineering by an anti-solvent to PVDF-HFP, the PVDF-HFP/EMIM:DCA ionogel doped with 0.5 mol% Na+ with respect to EMIM+ exhibits an ionic thermopower of 43.8 ± 1.0 mV K-1, ionic conductivity of 19.4 ± 0.3 mS cm^-1 and thermal conductivity of 0.183 W m-1 K-1 at the relative humidity of 85% and room temperature The corresponding ZTi value thus reaches 6.1 ± 0.4, much higher than the previous ZTi records of iTE materials. These ionogels can be used in the iTE capacitors for the thermoelec. conversion.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
