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).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride

Heterogeneous asymmetric passable cavities within graphene oxide nanochannels for highly efficient lithium sieving was written by Ahmadi, Hadi;Zakertabrizi, Mohammad;Hosseini, Ehsan;Cha-Umpong, Withita;Abdollahzadeh, Mojtaba;Korayem, Asghar Habibnejad;Chen, Vicki;Shon, Ho Kyong;Asadnia, Mohsen;Razmjou, Amir. And the article was included in Desalination in 2022.Synthetic Route of ClLi The following contents are mentioned in the article:

Lithium is a critical energy element that plays a pivotal role in transitions to sustainable energy. Numerous two-dimensional (2D) membranes have been developed to extract Li+ from different resources. However, their Li+ extraction efficacy is not high enough to meet industrial requirements. Here, we introduce an approach that boosts Li+ selectivity of 2D membranes by inducing asymmetricity in the morphol. and chem. of their nanochannels. Our approach provides an opportunity to manipulate cation hydration shells via a sudden change in the nanochannel size. Then, the addition of nucleophilic traps in the nanochannel intersections results in high Li+ selectivity. Our design leads to a new ion transport mechanism named “Energy Surge Baffle” (ESB) that substantially enriches Li+ in the feed by increasing the monovalent/lithium-ion selectivity up to six times that of other graphene oxide-based membranes. Our approach can be extended to other 2D materials, creating a platform for designing advanced membranes. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Synthetic Route of ClLi).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. 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).Synthetic Route of ClLi

Development of novel thin-film solid-phase microextraction materials based on deep eutectic solvents for preconcentration of trace amounts of parabens in surface waters was written by Werner, Justyna;Zgola-Grzeskowiak, Agnieszka;Grzeskowiak, Tomasz. And the article was included in Journal of Separation Science in 2022.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

A green and sensitive thin-film solid-phase microextraction method based on deep eutectic solvent was developed that enables simultaneous isolation, preconcentration, and determination of parabens in surface waters. Six new deep eutectic solvents were synthesized and used directly to prepare thin-film coatings on a stainless steel mesh support. Among the compounds obtained, the highest efficiency in the extraction of parabens was found for a material consisting of trihexyltetradecylphosphonium chloride and n-docosanol in a molar ratio of 1:2. For the proposed method, parameters affecting the extraction efficiency of parabens, such as the coating material, the desorption solvent, the volume of the sample, the pH of the sample, the extraction and desorption time, and the salting-out effect, were optimized. Under optimal conditions, the proposed method allowed us to achieve good precision between 3.6 and 6.5% and recovery ranging from 68.1 to 91.4%. The limits of detection range from 0.018 to 0.055 ng/mL.

Comparison of four methods of predicting newly measured octanol/water coefficients (Log K_ow) for heterocyclic nitrogen compounds and the partition mechanism was written by Li, Li;Wang, Liansheng;Han, Shuokui;Zhang, Zheng. And the article was included in Environmental Toxicology and Chemistry in 1999.Quality Control of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:

Log K_ow values for 14 heterocyclic nitrogen compounds (by traditional shake-flask method) were reported. Reverse phase-high-performance liquid chromatog. (RP-HPLC) method and three estimation models-linear solvation energy relationship, mol. connectivity indexes (MCIs), and quantum chem. descriptors-were used to study the partition mechanism and to establish the correlations of the models with the measured log K_ow values by stepwise variable regression. Research on the partition mechanism showed that the mol. bulk properties and the hydrogen bond interaction were the most important factors influencing the partition process. Comparison of the quality of the models was made among the four methods. According to the simplicity of the method, the availability of the descriptors, and the closeness of correlation with the measured log K_ow values, the RP-HPLC method was not satisfactory, while the MCIs method introducing the non-disperse force factor was the most satisfactory. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Quality Control of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).

4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

Viral mRNA cap methyltransferases (MTases) are emerging targets for the development of broad-spectrum antiviral agents. In this work, we designed potential SARS-CoV-2 MTase Nsp14 and Nsp16 inhibitors by using bioisosteric substitution of the sulfonium and amino acid substructures of the cosubstrate S-adenosylmethionine (SAM), which serves as the Me donor in the enzymic reaction. The synthetically accessible target structures were prioritized using mol. docking. Testing of the inhibitory activity of the synthesized compounds showed nanomolar to submicromolar IC₅₀ values for 5 compounds To evaluate selectivity, enzymic inhibition of the human glycine N-methyltransferase involved in cellular SAM/SAH ratio regulation was also determined, which indicated that the discovered compounds are nonselective inhibitors of the studied MTases with slight selectivity for Nsp16. No cytotoxic effects were observed; however, this is most likely a result of the poor cell permeability of all evaluated compounds This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Electric Literature of C6H9ClO3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways.

And the article was included in Applied Surface Science in 2022.Product Details of 13820-53-6 The following contents are mentioned in the article:

Cocatalyst can greatly facilitate the charge separation efficiency and decrease the activation barrier of a specific reaction, thus contributing the improved photocatalytic performance. Herein, PdS/CdS/MoS₂ was synthesized via a facile microwave-assisted approach. Owing to the coexistence of PdS and MoS₂, resp. serving as oxidation and reduction cocatalyst, PdS/CdS/MoS₂ displayed enhanced photocatalytic performance in both hydrogen production (6610 μmol·g^-1·h^-1) and benzylamine oxidation (87% conversion) in comparison with the individual and binary composite counterparts. The improved photocatalytic activity was mainly attributed to the high charge separation efficiency and lowed activation barrier. Furthermore, the introduction of PdS can timely extract photogenerated holes from CdS, which effectively inhibits the photo-corrosion of CdS, endowing it with high stability. This work paves the way for developing efficient chalcogenide photocatalysts.

Recovery of Lithium Carbonate from Dilute Li-Rich Brine via Homogenous and Heterogeneous Precipitation was written by Battaglia, Giuseppe;Berkemeyer, Leon;Cipollina, Andrea;Cortina, Jose Luis;Fernandez de Labastida, Marc;Lopez Rodriguez, Julio;Winter, Daniel. And the article was included in Industrial & Engineering Chemistry Research in 2022.Computed Properties of ClLi The following contents are mentioned in the article:

An extensive exptl. campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li⁺ ~4000 ppm) is presented to identify the best operating conditions for a Li₂CO₃ crystallization unit. Lithium is currently mainly produced via solar evaporation, purification, and precipitation from highly concentrated Li brines located in a few world areas. The process requires large surfaces and long times (18-24 mo) to concentrate Li⁺ up to 20,000 ppm. The present work investigates two separation routes to extract Li⁺ from synthetic solutions, mimicking those obtained from low-content Li⁺ sources through selective Li⁺ separation and further concentration steps: (i) addition of Na₂CO₃ solution and (ii) addition of NaOH solution + CO₂ insufflation. A Li recovery up to 80% and purities up to 99% at 80°C and with high-ionic strength solutions was achieved employing NaOH solution + CO₂ insufflation and an ethanol washing step. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Computed Properties of ClLi).

Lithium chloride (cas: 7447-41-8) 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. 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).Computed Properties of ClLi

Recovery of lead and iodine from spent perovskite solar cells in molten salt was written by Wang, Hongya;Chen, Xiang;Li, Xianyang;Qu, Jiakang;Xie, Hongwei;Gao, Shuaibo;Wang, Dihua;Yin, Huayi. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Organic-inorganic hybrid perovskite solar cells (PSCs) have received extensive attention due to their high power conversion efficiency, bright prospects for large-scale deployment, and low cost. However, the end-of-life lead (Pb)-based PSC will pose significant resource and environmental challenges. Herein, we develop an eco-friendly strategy, the molten-salt-electrolysis (MSE), to recover Pb and iodine (I₂) from spent Pb-based PSC. First, lead iodide (PbI₂) was dissolved in molten LiCl-KCl and then electrochem. converted into I₂ at a graphite anode and Pb at the cathode. The recovery efficiency of Pb reached 97.65% with a high current efficiency of 96.87%. In addition, a high PbI₂ leaching rate of ∼ 99.8% and a high PbI₂ solubility of ∼ 5.97 weight% in molten LiCl-KCl at 450°C can sustain a rapid leaching and recovery process. Overall, MSE is a simple, rapid, and environmental-benign method to recover Pb-based PSCs, eliminating the Pb contamination and closing the iodine cycle.

Chiral alcs. and their derivatives are vital building blocks to synthesize pharmaceutical drugs and high-valued chems. Wild-type carbonyl reductase AcCR from Acetobacter sp. has ideal enantioselectivity toward 11 prochiral substrates (e.e.>99%) but poor activity. In this work, a semi-rational engineering was performed to enhance the activity of AcCR. Fortunately, three pos. double-mutants (mut-E144A/G152L, mut-G152L/Y189 N, and mut-I147 V/G152L) with specific activity 17-61 folds higher than that of enzyme without modified were achieved. Kinetic studies suggested that the catalytic efficiencies (k_cat/K_m) of these mutants were also well enhanced. Finally, these modified mut-AcCRs were successfully applied in asym. reductions of 11 structurally diverse prochiral substrates (200 mM) with excellent product yields (76.8%-99.1%) and enantiomeric excess (e.e.>99%), which provides an alternative strategy for efficient synthesis of chiral alcs. for pharmaceuticals industry with ideal yield and enantioselectivity.
