Ultralow-Loading and High-Performing Ionic Liquid-Immobilizing Rhodium Single-Atom Catalysts for Hydroformylation was written by Wei, Xinjia;Jiang, Yongjun;Ma, Yuan;Fang, Jian;Peng, Qingpo;Xu, Wen;Liao, Huiying;Zhang, Fengxue;Dai, Sheng;Hou, Zhenshan. And the article was included in Chemistry – A European Journal in 2022.Related Products of 5137-55-3 The following contents are mentioned in the article:

We have developed a Keggin polyoxometalate (POM)-based ionic-liquid (IL)-immobilizing rhodium single-atom Rh catalyst (MTOA)₅[SiW₁₁O₃₉Rh] (MOTA=methyltrioctylammonium cation) that can afford exceptionally high catalytic activity for the hydroformylation of alkenes to produce aldehydes at an ultralow loading of Rh (ca. 3 ppm). For styrene hydroformylation, both the conversion and the yield of the aldehyde can reach almost 99 %, and a TOF as high as 9000 h^-1 was obtained without using any phosphine ligand in the reaction process. Further characterization by FTIR, ICP and ESI-MS anal. revealed that the single Rh atom was incorporated in the lacunary POM anions. In particular, the bulky IL cation can play an addnl. role in stabilizing Rh species and thus prevent aggregation and leaching of Rh species. The IL catalyst was miscible with n-hexane at temperatures; this contributed to exceptionally high activity for hydroformylation even at ultra-low loading of IL catalyst.

Extraction of Cu(II), Fe(III), Zn(II), and Mn(II) from Aqueous Solutions with Ionic Liquid R4NCy was written by Castillo, Jonathan;Toro, Norman;Hernandez, Pia;Navarro, Patricio;Vargas, Cristian;Galvez, Edelmira;Sepulveda, Rossana. And the article was included in Metals (Basel, Switzerland) in 2021.Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

The leaching of copper ores produces a rich solution with metal interferences. In this context, Fe(III), Zn(II), and Mn(II) are three metals contained in industrial copper-rich solutions in high quantities and eventually can be co-extracted with the copper. The purpose of the current study was to determine the feasibly of solvent extraction with the use of ionic liquid methyltrioctyl/decylammonium bis (2,4,4-trimethylpentyl)phosphinate (R4NCy) as an extractant of Cu(II) in the presence of Fe(III), Zn(II), and Mn(II). In general terms, the results showed a high single extraction efficiency of all the metals under study. In the case of Fe(III) and Zn(II), the extraction was close to 100%. On the contrary, the stripping efficiency was poor to Fe(III) and discrete to Zn(II), but very high to Cu(II) and Mn(II). Finally, the findings of this study suggest that the ionic liquid R4NCy is feasible for the pre-treatment of the copper solvent extraction process to remove metal impurities such as Fe(III) and Zn(II). This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride).

And the article was included in Doklady Chemistry in 2021.Application of 5137-55-3 The following contents are mentioned in the article:

The isomolar series method was used to identify the regions of synergistic extraction of praseodymium and neodymium from low-acid nitrate solutions containing ammonium nitrate as a salting-out agent with isomolar mixtures of tri-n-octyl(methyl)ammonium nitrate and tri-Bu phosphate in toluene. The synergistic effect in the praseodymium extraction was detected for a limited range of mixture compositions, while in the case of neodymium extraction, this effect was manifested over the whole range of studied compositions It was found that the chem. of synergistic extraction is determined by the formation of a continuous sequence of mixed praseodymium or neodymium complexes, with antiparallel variation of the number of extractant mols. in the complexes and the extractant molar ratio. As the concentration of quaternary ammonium nitrate in the mixture increases, the phosphoryl groups of tri-Bu phosphate are replaced by the nitrate ligands of the quaternary salt, up to their complete displacement from the lanthanide coordination sphere. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application of 5137-55-3).

An ionic liquid Aliquat 336 was for the first time analyzed for its adsorption and corrosion inhibition behavior for carbon steel surface in 0.5 M H₂SO₄. The inhibition performance was studied using gravimetric and electrochem. techniques supported by surface anal. measurements. The inhibitor exerted an efficiency of 96.53% at 12×10^-6 M. Significant improvement was achieved with iodide ions, which at 3.01×10^-4 M, produced a remarkable rise in the efficiency to 99.03%. The adsorption of the inhibitor on the metallic surface followed the Langmuir isotherm at 298 K in the concentration range of 2.47 to 12.37×10^-6 M. Polarization studies indicated a mixed-mode of inhibitor action with the cathodic predominance. The SEM studies showed a smooth metal surface in contact with the inhibitor, and a representative decrease in surface roughness was observed by AFM studies. Monte Carlo simulations showed inhibitor adsorption in a flat orientation on the metal surface with high adsorption energy.

Experimental and modeling investigation of organic modified montmorillonite with octyl quaternary ammonium salt was written by Liu, Hongyan;Guo, Chengxin;Cui, Yingna;Yin, Jingmei;Li, Shenmin. And the article was included in Scientific Reports in 2022.Electric Literature of C25H54ClN The following contents are mentioned in the article:

The sodium montmorillonite was organic modified with three kinds of quaternary ammonium salts containing 1 to 3 octyl chains, and then the organic montmorillonite was studied by FT-IR, XRD, and TG characterization as well as Monte Carlo simulations, to explore the influence of the number of octyl chains and the loading of intercalated cations on the basal spacing (d001) of the modified montmorillonite complexes. According to the distribution of intercalated quaternary ammonium cations and the energy change of the montmorillonite complexes, a reasonable explanation was given for the enlargement of the interlayer space. The results of exptl. characterization and Monte Carlo simulations show that all the three intercalation agents can enlarge the interlayer space of montmorillonite complexes. The more the number of octyl chains in the salt, the more significant expanding effect on the interlayer space. The three intercalation cations exhibited a distribution arranged from mono-layered to multi-layered structure as the loading of intercalated cations increases.
