The aim of this research was to investigate ciprofloxacin (CIP) removal efficiency from aqueous solutions by using Fe₃O₄ nanoparticles @Trioctylmethylammonium thiosalicylat Ionic liquid (Fe₃O₄ NP@ TOMATS IL) as a new magnetic nanoadsorbent. The adsorbent was characterized by field emission scanning electron microscope-energy dispersive spectroscopy (FESEM-EDS), mapping, Fourier transform IR spectroscopy (FT-IR), the Brunauer-Emmett-Teller (BET), X-ray powder diffraction (XRD). The effects of solution pH, adsorbent dose, contact time, initial CIP concentration, and temperature on CIP removal were also investigated. In optimal conditions such as pH = 5.6, CIP concentration = 30 mg/L, adsorbent dose = 0.15 g, temperature = 30°C, contact time = 90 min, the removal efficiency in synthetic and real wastewater were obtained 87 and 73%, resp. Batch experiments were carried out to study the sorption Kinetics, thermodn., and equilibrium isotherms of CIP with magnetic nanoadsorbent. The results show that all of the above factors influence CIP removal. The Langmuir adsorption isotherm fits the adsorption process well, with the pseudo second-order model describing the adsorption kinetics accurately. The thermodn. parameters indicate that adsorption is mainly phys. adsorption. Recycling experiments revealed that the behavior of adsorbent is maintained after recycling for four times. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Formula: C25H54ClN).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Formula: C25H54ClN

Decomposition Kinetics of H₂O₂ on Pd Nanocrystals with Different Shapes and Surface Strains was written by Shi, Yifeng;Elnabawy, Ahmed O.;Gilroy, Kyle D.;Hood, Zachary D.;Chen, Ruhui;Wang, Chenxiao;Mavrikakis, Manos;Xia, Younan. And the article was included in ChemCatChem in 2022.Related Products of 13820-53-6 The following contents are mentioned in the article:

Direct synthesis of hydrogen peroxide (H₂O₂) from H₂ and O₂ on a Pd-based catalyst has emerged as a promising route to replace the energy-consuming, highly inefficient anthraquinone process. However, Pd is also a good catalyst for the decomposition of H₂O₂, thereby compromising the selectivity toward the desired product. The coupling between the formation and decomposition reactions makes it difficult to single out the most important parameter that controls the selectivity toward direct synthesis of H₂O₂. Herein, support-free monometallic Pd nanocrystals with different shapes and surface strains are used to investigate their impacts on the decomposition kinetics of H₂O₂. The kinetics are analyzed by tracking the concentration of the remaining H₂O₂ using IR spectroscopy. The data indicates that both surface structure and strain affect the decomposition kinetics of H₂O₂, but their impacts are inferior to that caused by Br-, a surface capping agent for the Pd{100} facets. The exptl. results are consistent with the trend obtained through d. functional theory calculations This work helps shed light on the development of Pd-based catalysts for the direct synthesis of H₂O₂ by offering strategies to mitigate the decomposition of the desired product. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Related Products of 13820-53-6).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) 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).Related Products of 13820-53-6

The Influence of Ionic Liquids Adsorption on the Electronic and Optical Properties of Phosphorene and Arsenene with Different Phases: A Computational Study was written by Zhu, Lin;Fu, Aiping. And the article was included in Molecules in 2022.Application of 75-57-0 The following contents are mentioned in the article:

D. functional theory (DFT) calculations have been performed to investigate the interfacial interactions of ionic liquids (ILs) on the α- and β-phases of phosphorene (P) and arsenene (As). Nine representative ILs based on the combinations of 1-ethyl-3-methylimidazolium ([EMIM]⁺), N-methylpyridinium ([MPI]⁺), and trimethylamine ([TMA]⁺) cations paired to tetrafluoroborate ([BF4]^–), trifluoromethanesulfonate ([TFO]^–), and chloridion (Cl^–) anions were used as adsorbates on the 2D P and As nanosheets with different phases to explore the effect of IL adsorption on the electronic and optical properties of 2D materials. The calculated structure, adsorption energy, and charge transfer suggest that the interaction between ILs and P and As nanosheets is dominated by noncovalent forces, and the most stable adsorption structures are characterized by the simultaneous interaction of the cation and anion with the surface, irresp. of the types of ILs and surfaces. Furthermore, the IL adsorption leads to the larger change in the electronic properties of β-phase P and As than those of their α-phase counterparts, which demonstrates that the adsorption properties are not only related to the chem. elements, but also closely related to the phase structures. The present results provide insight into the further applications of ILs and phosphorene (arsenene) hybrid materials. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Application of 75-57-0).

Continuous flow synthesis of plasmonic gold patches and nearly-complete nanoshells on polystyrene core particles was written by Meincke, Thomas;Klupp Taylor, Robin N.. And the article was included in Particuology in 2023.Synthetic Route of C4H12ClN The following contents are mentioned in the article:

We describe the development of a T-mixer based continuous flow process for the coating of 86-500 nm diameter spherical polystyrene particles with thin gold patches by heterogeneous nucleation and growth. After establishing a suitable flow rate for good mixing and sufficiently uniform product morphol. we systematically investigate the main reaction parameters. This reveals a considerable tunability of the patch morphol. and, by virtue of the localized surface plasmon resonance of gold, the optical properties of the product dispersions. In order to further widen the range of nanostructures accessible by our process, a second T-mixer was added. This introduced new gold precursor, leading to further growth of the patches that were formed after the first mixer. By this approach, nearly-complete gold nanoshells could be produced in high yield on both small and large core particles, without the unwanted production of free-standing gold nanoparticles. Due to the pronounced optical properties of nearly-complete gold nanoshells on small core particles, we could estimate from electrodynamic simulations the equivalent shell thickness to be as low as 8.6 nm. This is significantly thinner than can be routinely achieved using the standard seeded growth approach to synthesize gold nanoshells. Our results are therefore highly promising for the gram-scale synthesis of plasmon resonant nanostructures with designed optical properties. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Synthetic Route of C4H12ClN).

Tetramethylammonium chloride (cas: 75-57-0) 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. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Synthetic Route of C4H12ClN

Fabrication of thin film composite polyamide membrane for water purification via inkjet printing of aqueous and solvent inks was written by Park, Myoung Jun;Wang, Chen;Gonzales, Ralph Rolly;Phuntsho, Sherub;Matsuyama, Hideto;Drioli, Enrico;Shon, Ho Kyong. And the article was included in Desalination in 2022.Related Products of 7447-41-8 The following contents are mentioned in the article:

Thin film composite (TFC) polyamide (PA) membranes are typically prepared using the interfacial polymerization (IP) method, which synthesizes the PA layer by soaking in aqueous diamine and organic acyl chloride solutions and allowing the occurrence of amidation. The conventional IP process has been used over several decades in the industrial production of TFC membranes for water purification and excess amounts of monomer solutions are used for PA thin film layer synthesis, generating a lot of chem. wastes. In this work, we first demonstrated the TFC PA membrane fabrication using simple inkjet printing of aqueous and organic inks to effectively prepare a PA layer with no chem. wastes. The organic acyl chloride ink was newly formulated by the combination of dodecane and toluene solvents to allow printability. Precise and uniform depositions of monomer inks via the inkjet printing approach were able to coat a dense and defect-free PA film onto the support membrane using only small volumes of chems. After multiple printing numbers of inks, the PA layer was optimized with two printing cycles (30.17 mL m^-2) and three printing cycles (8.36 mL m^-2) of diamine and triacyl chloride inks, resp., followed by heat treatment. The inkjet-printed TFC-M2T3-15 membrane exhibited a high salt rejection (95.33%) which showed higher performance compared to that of the conventional IP-prepared TFC membrane (89.64%). This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Related Products of 7447-41-8).

Lithium chloride (cas: 7447-41-8) 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.

Fine-tuning interlayer spacing in MoS₂ for enriching 1T phase via alkylated ammonium ions for electrocatalytic hydrogen evolution reaction was written by Venkateshwaran, Selvaraj;Josline, Mukkath Joseph;Senthil Kumar, Sakkarapalayam Murugesan. And the article was included in International Journal of Hydrogen Energy in 2021.HPLC of Formula: 75-57-0 The following contents are mentioned in the article:

An environmentally benign pathway for com. production of mol. hydrogen can be made by electrocatalytic water splitting, which requires highly active catalyst like Pt. Nowadays, 1T MoS₂ is recognized as a good alternate to Pt in hydrogen evolution reaction (HER) by virtue of its dense active sites, hydrophilicity and enhanced electronic conductivity However the formation of such phase is still challenging as being 2H is the most stable phase of MoS₂. Here, a simple hydrothermal approach is followed, wherein alkylated ammonium ion introduction between layers of MoS₂, was employed for 1T phase enriched MoS₂ formation, aiming to elucidate the influence of the intercalated ions on the interlayer expansion as well as the selective formation of the 1T phase. Me ammonium ion was found to be the most apt for 1T phase enrichment as over 70% was achieved and the resultant MoS₂ exhibits magnificent HER activity with a low Tafel slope of 56 mV/dec and required just 270 mV overpotential to attain a c.d. of 10 mA cm^-2 with robust durability. The optimum variations in interlayer, rich 1T phase formation are the key findings of this study. This investigation opens up new strategy i.e., interlayer expansion induced enrichment of 1T phase via alkylated ammonium ions will be highly useful for other 2D layered materials in near future for energy related HER applications.

How the type of interface can alter the behavior of an aprotic ionic liquid-water mixture entrapped in different reverse micelles: An exploratory study using an enzymatic reaction as a sensor was written by Blach, Diana;Girardi, Valeria R.;Silber, Juana J.;Correa, N. Mariano;Falcone, R. Dario. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Electric Literature of C25H46ClN The following contents are mentioned in the article:

In this work, we decipher how an aprotic Ionic Liquid (IL)-water mixture structure can be altered upon confinement in different reverse micelles (RMs) media. Thus, the effect of the polar pseudophase composition in RMs formulated by anionic or cationic surfactants was monitored using the well-known enzymic hydrolysis reaction of 1-naphthyl phosphate (1-NP) with alk. phosphatase (AP). Water and an aqueous mixture formed by the IL 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([C4C1i.m., TfO]) as the polar pseudophase were used. As surfactants, the anionic sodium diethylhexyl sulfosuccinate (AOT) and the cationic benzyl-n-hexadecyldimethylammonium chloride (BHDC) were employed. The effect of the nanoconfinement, as well as the impact of the polar solvent content and the type of interface, were analyzed by determining the Michaelis-Menten parameters. In homogeneous media, the catalytic efficiency of the hydrolysis reaction is strongly dependent on the amount of water in the mixtures evaluated. In RMs the catalytic efficiency is dependent on both, the polar content and the type of surfactant used. Thus, by using a model reaction with an enzyme entrapped inside different RMs it was possible to learn that an aprotic IL:water mixture can be strongly disturbed when it is confined in a cationic or anionic RMs. This particular behavior can produce a deep impact on the technol. applications of these organized systems.

Ultrasound-assisted sample preparation for simultaneous extraction of anionic, cationic and non-ionic surfactants in sediment was written by Wiest, Laure;Giroud, Barbara;Fieu, Maeva;Assoumani, Azziz;Lestremau, Francois;Vulliet, Emmanuelle. And the article was included in Talanta in 2022.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Despite their very wide use in various fields, knowledge concerning surfactants in environmental solid matrixes is generally poor. One of the difficulties encountered in the anal. of surfactants is their very diverse physicochem. properties which require different extraction techniques. The objective of this work was therefore to develop an extraction method in sediments that allows the simultaneous anal. of anionic, cationic and non-ionic surfactants. Different extraction techniques (salting-out, ultrasound), solvents and additives were compared. The optimized method, followed by anal. by coupling liquid chromatog. with tandem mass spectrometry, was then validated and applied to real samples in which the analytes were quantified by matrix matched calibration. Optimization of the extraction parameters showed different trends depending on the surfactant family. However, ultrasound assisted extraction with a 90/10 acetonitrile/water mixture at 1% acetic acid and 0.1 M EDTA showed the best results overall. The quantification limits obtained, between 6.4μg/kg for linear alkylbenzene sulfonate (LAS) C10 and 158μg/kg for 1-laureth sulfate, allow the anal. of traces in sediments. Eighteen of the 27 targeted surfactants were thus detected. The highest concentrations were found for LAS and quaternary ammoniums. Strong correlations between concentrations of different homologues of the same families of surfactants were observed This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Recommanded Product: 122-18-9).

Design of metal salt/amide-based deep eutectic monomers toward sustainable production of ion-conductive polymers by radical polymerization was written by Tanaka, Y.;Ajino, K.;Ogawa, H.;Mori, H.. And the article was included in Materials Today Chemistry in 2022.Recommanded Product: 7447-41-8 The following contents are mentioned in the article:

We herein describe a solvent-free synthetic route to ion-conductive polymers from metal salt/amide-based deep eutectic monomers (DEMs), which were prepared by mixing amido-containing solid monomers with metal salts under suitable feed ratios. N-Iso-Pr acrylamide (NIPAM) and N-vinylacetamide (NVA) were selected as vinyl monomers bearing an amido functional group that can act as a hydrogen bond donor. Lithium chloride (LiCl), zinc chloride (ZnCl2), and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), which can act as hydrogen bond acceptors, were employed as metal salts. The simple mixing of NIPAM with solid LiTFSI in a 5:1 M ratio at 60°C for 0.5 h afforded liquid NIPAM/0.2LiTFSI, which exhibited the characteristic eutectic effect. By mixing NIPMA with ZnCl₂ in a suitable feed ratio, NIPAM/0.25ZnCl₂ was obtained as a white turbid liquid at room temperature Similarly, NVA/0.2LiCl and NVA/0.2LiTFSI were obtained as transparent liquids from solid NVA. In addition, the thermally-induced free-radical polymerization of the metal salt/amide-based DEMs in the bulk and in solution resulted in the formation of the corresponding polymers. Poly(NVA/0.2LiTFSI) exhibited the highest ionic conductivity of 2.83 x 10-6 S/cm at 50°C. These results reveal that the DEMs developed in this study can provide a green and sustainable process for the radically-induced production of novel ion-conductive polymers in air.

Application of hydrophobic deep eutectic solvent for the extraction of aromatic compounds from contaminated water was written by Yakubu, Abdullahi;Gano, Zaharaddeen Sani;Ahmed, Omar Umar;Shuwa, Suleiman Mohammed;Atta, Abdulazeez Yusuf;Jibril, Baba Yakubu. And the article was included in Korean Journal of Chemical Engineering in 2022.Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

Hydrophobic deep eutectic solvent (DES) was synthesized from TBAB and decanoic acid and used to study the extraction of aromatic hydrocarbon from contaminated water samples. DES was screened by selecting different ratios between the TBAB and decanoic acid. A ratio of 1: 2 was observed to be the best among others and was used for the desired application. Within the temperature range of 25-70°C, physicochem. properties such as d. (944-915 kg/m³), viscosity (1,636-179 mPa·s), conductivity (141-1,007μS/cm), and pH (3.14-2.73) of the synthesized DES were determined For the extraction study, benzene, toluene, and xylene (BTX)-doped water were used as a simulated contaminated water. Response surface methodol. was employed in modeling and optimizing the effects of temperature, time, and solvent mass fraction on the extraction efficiency of the DES. Extraction efficiency of 68.1%, 70.84% and 77.73% for BTX, resp., was recorded at optimum values of 25°C, 60 min and 0.6 (solvent mass fraction). Extraction efficiency as high as 86.61%, 88.94%, and 92.71% for BTX, resp., can be obtained within the design space. Effective regeneration and reuse of the DES after each extraction was carried out for five consecutive cycles; their results showed no significant decrease in their resp. extraction efficiencies and recovery of the DES. This, therefore, improves the overall performance of hydrophobic DES for the extraction process.
