Investigation of Electrical Conductivity Properties and Electro Transport of a Novel Multi Walled Carbon Nanotube Electro Membrane under Constant Current was written by Onac, Canan. And the article was included in Electroanalysis in 2020.Reference of 5137-55-3 The following contents are mentioned in the article:

This study used multi-walled C nanotube in electro-membrane extraction studies under direct constant current for the 1st time for the electro transport of cypermethrin (CYP) from aqueous to acceptor phase. A novel and developed membrane exhibits visible and remarkable recovery values (82.76%) for the removal of CYP under 0.3 A constant current at 60 V in 30 min. Regenerating electro membrane by multi-walled C nanotubes (MWCNTs) increased the elec. conductivity, thermal Ea values of a novel membrane (750 meV) and stability, and it resulted in better and higher kinetic results on the transport process. This study presents a potential solution for the limited use of electro-membrane extraction at higher current values. Regenerating of the electro membrane by MWCNTs not only allows the authors to work even at high current values, it prevents the formation of electrolysis up to a certain current value in donor and acceptor phases. TGA of the novel membrane also confirms successful regeneration of the electro membrane by MWCNTs. Electro-membrane extraction studies have gained a new perspective and innovation using MWCNTs in electro-membrane process. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Reference of 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Reference of 5137-55-3

And the article was included in Microchemical Journal in 2021.Computed Properties of C25H54ClN The following contents are mentioned in the article:

In present study, DL-lactic acid/trioctylmethylammonium chloride-based deep eutectic solvent (DES), which was considered as an environmental friendly extraction solvent to replace traditional organic reagent, was firstly presented for monitoring of trace cadmium (Cd) and arsenic (As) in wine samples by ultrasonic-assisted dispersive liquid-liquid microextraction (UA-DLLME) method. Moreover, different extraction conditions, including the type and volume of DES and dispersive solvent, pH of the solution, salt amount, time of vortex and sonication, were systematically evaluated. At the optimized extraction conditions, good linear relationships (0.50-8.0μg·L^-1 for Cd, 2.0-50μg·L^-1 for As) were obtained and limits of detection of Cd and As were 0.080 and 0.30μg·L^-1, resp. In addition, the accuracy (as recoveries %), and intra-/inter-day precision (as relative standard deviation %) were in the ranges of 90.6-103.6% and 2.9-4.5%, resp. Finally, the proposed method was applied to analyze 6 kinds of wine samples, which possessed wide practical application value in monitoring heavy metal residues in wine and even complex food matrixes. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Computed Properties of C25H54ClN).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Computed Properties of C25H54ClN

Selective Catalytic Synthesis of 1,2- and 8,9-Cyclic Limonene Carbonates as Versatile Building Blocks for Novel Hydroxyurethanes was written by Maltby, Katarzyna A.;Hutchby, Marc;Plucinski, Pawel;Davidson, Matthew G.;Hintermair, Ulrich. And the article was included in Chemistry – A European Journal in 2020.HPLC of Formula: 5137-55-3 The following contents are mentioned in the article:

The selective catalytic synthesis of limonene-derived monofunctional cyclic carbonates and their subsequent functionalization via thiol-ene addition and amine ring-opening is reported. A phosphotungstate polyoxometalate catalyst used for limonene epoxidation in the 1,2-position is shown to also be active in cyclic carbonate synthesis, allowing a two-step, one-pot synthesis without intermittent epoxide isolation. When used in conjunction with a classical halide catalyst, the polyoxometalate increased the rate of carbonation in a synergistic double-activation of both substrates. The cis isomer is shown to be responsible for incomplete conversion and byproduct formation in com. mixtures of 1,2-limonene oxide. Carbonation of 8,9-limonene epoxide furnished the 8,9-limonene carbonate for the first time. Both cyclic carbonates underwent thiol-ene addition reactions to yield linked di-monocarbonates, which can be used in linear non-isocyanate polyurethane synthesis, as shown by their facile ring-opening with N-hexylamine. Thus, the selective catalytic route to monofunctional limonene carbonates gives straightforward access to monomers for novel bio-based polymers. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3HPLC of Formula: 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.HPLC of Formula: 5137-55-3

An extraction method employing dispersive liquid-liquid microextraction (DLLME) and ICP-OES has been developed for rapid separation, pre-concentration and determination of ultra-trace amount of Au(III). The extraction of the analyte was performed in the presence of a quaternary ammonium cation, N-Methyl-N, N, N-trioctylammonium chloride, (Aliquat 336) as an extractant based on ion-association extraction system. 1-octanol and acetonitrile were used as extraction and disperser solvents, resp. The variables affecting the extraction conditions were optimized. Calibration curve in the range of 0.3-100 ng mL^-1, the detection limit of 0.09 ng mL^-1, enrichment factor of 150 and extraction recovery of 74% were obtained.

Separation and adsorption of V(V) from canadium-containing solution by TOMAC-impregnated resins was written by Yu, Chen;Bao, Shenxu;Zhang, Yimin;Chen, Bo. And the article was included in Chemical Engineering Research and Design in 2021.Name: N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

Trioctyl Me ammonium chloride-impregnated resins (TOMAC-IRs) were synthesized and utilized to efficiently sep. and recover vanadium from acidic vanadium-containing solution, and the main factors affecting the adsorption properties of V(V) were studied. Under the optimal conditions, i.e., initial pH of 1.8, liquid-solid ratio (L/S) of 200:1 mL/g, impregnation ratio of 18.4%, initial vanadium concentration of 1500 mg/L, and adsorption time of 4 h, the adsorption capacity towards V(V) can reach 78.65 mg/g, and impurity ions (Al and Fe) can be hardly adsorbed. The adsorption of V(V) onto TOMAC-IRs conforms to the Langmuir isotherm adsorption model, indicating that V(V) is adsorbed as a monolayer on TOMAC-IRs. The pseudo-second order kinetic model fits better towards the adsorption processes of V(V), which shows that the adsorption process is dominated by chem. adsorption. The desorption and regeneration of the TOMAC-IRs can be accomplished in just one step using 6 mol/L NaOH; in the meanwhile, the adsorption capacity is 98.01% of the original value after six cycles, demonstrating that the TOMAC-IRs have good stability during the cyclic adsorption of V(V). This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Name: N-Methyl-N,N-dioctyloctan-1-aminium chloride).

Efficient and environment-friendly vanadium (V) extraction from vanadium shale leachate using tri-n-octylmethylammonium chloride was written by Luo, Dashuang;Huang, Jing;Zhang, Yimin;Liu, Hong;Hu, Pengcheng. And the article was included in Separation and Purification Technology in 2020.Reference of 5137-55-3 The following contents are mentioned in the article:

In this work, an efficient and environmentally friendly method for recovering V (V) from vanadium shale leachate using an ionic liquid, tri-n-octylmethylammonium chloride (TOMAC), was proposed. The main factors affecting the extraction and stripping of vanadium using TOMAC were studied. A significant quantity (93.18%) of vanadium was extracted with almost no impurities under the following conditions: the concentration of TOMAC was 20 vol%; the concentration of 2-octanol as the phase modifier was 15 vol%; the phase ratio (O/A) was 1:10. More than 90% of vanadium in the loaded organic phase could be stripped quant. using a mixed solution of 0.8 mol/L NaOH and 1.2 mol/L NaCl. The stripping and regeneration of the loaded organic phase could be carried out in one step. Meanwhile, the anion exchange mechanism of extraction and stripping was analyzed by Fourier transform IR (FT-IR) spectroscopy. Moreover, the organic phase stripped by the NaOH-NaCl synergistic stripping system maintained a relatively high extraction efficiency (>90%) even across many cycles, which indicated that the developed system is environmentally friendly and efficient for the recovery of vanadium. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Reference of 5137-55-3).

Two step activation of Ru-PN³P pincer catalysts for CO₂ hydrogenation was written by Tossaint, Alex S.;Rebreyend, Christophe;Sinha, Vivek;Weber, Manuela;Canossa, Stefano;Pidko, Evgeny A.;Filonenko, Georgy A.. And the article was included in Catalysis Science & Technology in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Activation of homogeneous catalysts is an important step in ensuring efficient operation of any catalytic system as a whole. For the majority of pincer catalysts, the activation step leans heavily on the metal ligand cooperative chem. that allows these complexes to react with small mol. substrates and engage in catalytic transformations. While the majority of such catalysts require a single activation event to become cooperative, herein we report an exception to this trend. Specifically, we demonstrate that a Ru-PN³P aminopyridine pincer catalyst, which lacks conventional reactivity with hydrogen upon typical one-fold activation, can exhibit this reactivity when a sequential two-step activation is performed. The resulting anionic complexes readily activate mol. hydrogen and react further with CO₂ showing the previously unknown reactivity that is critical for CO₂ hydrogenation catalysts. While active in CO₂ hydrogenation, Ru-PN³Ps are significantly more efficient in hydrogenation of bicarbonates – a likely consequence of the chem. of these pincers requiring formation of anionic complexes for hydrogen activation.

And the article was included in Environmental Research in 2022.Electric Literature of C25H54ClN The following contents are mentioned in the article:

In this study, the ionic liquid (Aliquat-336) and anionic surfactant (cetyltrimethylammonium bromide, CTAB) bi-functionalized chitosan beads were prepared and characterised using different techniques, including FTIR, XRD, SEM, EDS and BET surface area anal. The characteristic anal. confirmed the successful conjugation of chitosan beads with both surfactant and ionic liquid The novel fabricated beads (CS-CTAB-AL) were efficiently employed, as a high-performance adsorbent, for the removal of Tartrazine (TZ), an anionic food dye, from polluted water. The optimum adsorption of TZ onto the CS-CTAB-AL was found at 2 g L-1 of adsorbent in the wide pH range of 4-11, whereas just 45 min was required to reach more than 90% adsorption efficiency in the studied conditions. Also, the adsorption and kinetic studies showed that the exptl. data well fitted the pseudo-first-order kinetic model and the Langmuir isotherm model. The maximum adsorption capacity of prepared beads was found to be 45.95 mg g-1 at 45°C. The adsorption properties of enabling CS-CTAB-AL conjugation introduced a new type of adsorbents, exploited the combination of ionic liquid and surfactant capabilities for wastewater treatment.

The nitrogen-doped carbon supported ultra-small vanadium nitride nanoparticles as a highly efficient oxygen reduction electrocatalyst for the rechargeable Zn-air battery was written by Zhang, Honghui;Wu, Suqin;Deng, Daijie;Wang, Huan;Xun, Suhang;Chen, Feng;Zhang, Jianming;Xu, Li. And the article was included in Inorganic Chemistry Communications in 2022.Reference of 5137-55-3 The following contents are mentioned in the article:

The regulating active sites of vanadium nitride (VN)-based materials is an effective way to improve their oxygen reduction reaction (ORR) performance, which is expected to effectively solve the problem of sluggish kinetics in the cathode of Zn-air batteries. However, traditional synthesis methods cannot uniformly disperse VN, cause inadequate exposure to the active site, resulting in poor ORR performance. Herein, the authors successfully prepared a nitrogen-doped carbon supported ultra-small vanadium nitride nanoparticles (VN/NC) by organic group modification combined with rapid calcination strategies. The size of VN nanoparticles is �-10 nm. The smaller size can ultimately improve the ORR performance of VN/NC by exposing more active sites. Finally, the half-wave potential of the VN/NC is 0.813 V for ORR. More importantly, the Zn-air batteries assembled with the VN/NC catalyst as the air cathode shows a high power d. (115 mW cm^-2) and a large specific capacity (673 mAh g^-1). This approach can successfully synthesize ultra-small size VN nanoparticles, which is of great significance to the development of efficient air cathode materials for the Zn-air battery.
