Separation studies were conducted to sep. palladium (Pd) or platinum (Pt) from acidic solutions using 15 hydrophobic ionic liquids (ILs) capable of forming a binary phase with acidic aqueous solution This study considered two cases. The first was to find high-efficient ILs capable of separating metals from a single solution, and the second was to find ILs capable of selectively separating Pt from an acidic mixture solution of Pd and Pt. In addition, we also considered toxic effect of ILs for greener separation process. For this studies, we exptl. examined the separation efficiencies of the ILs, and discuss the properties with their toxicities, theor. predicted by previously presented toxicity prediction model, were compared. The results revealed that the extraction efficiency of ILs for Pd and Pt from acidic solutions depends on the types of IL and metal concentration In the separation study on Pd in a single metal solution, trihexyltetradecylphosphonium bromide [P6,6,6,14]Br and trioctylmethylammonium chloride [N8,8,8,1]Cl efficiently separates Pd from acidic solutions, while the separation on Pt in its single metal solution, 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM1-1Bz][(CF₃SO₂)₂N], 1-methyl-3-dodecylimidazolim bis(trifluoromethylsulfonyl)imide [IM12][(CF₃SO₂)₂N], 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [IM16][(CF₃SO₂)₂N], [P6,6,6,14]Br and [N8,8,8,1]Cl led to high efficiencies. Moreover, in the study to selectively sep. Pt from a mixed solution of Pd and Pt, [IM1-1Bz][(CF₃SO₂)₂N] and [IM16][(CF₃SO₂)₂N] have significant separation efficiency. When comparing the efficiencies and toxicities of the two ILs, [IM1-1Bz][(CF₃SO₂)₂N] is more efficient, but it is more toxic than [IM16][(CF₃SO₂)₂N]. Thus, for sustainable development, [IM16][(CF₃SO₂)₂N] can be considered as a better option. Moreover, in order to understand the partitioning mechanisms of ILs we developed quant. structure-activity relationship models with R² values greater than 0.91. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Related Products of 5137-55-3).

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. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Related Products of 5137-55-3

Phase equilibria in the ternary systems LiCl-LiBr-H₂O and LiCl-LiBr-CH₃OH at 298 K was written by Zhang, Xue-Ping;Liu, You-Quan;Chang, Qiu-Hao;Zeng, Rong. And the article was included in Journal of Molecular Liquids in 2022.Computed Properties of ClLi The following contents are mentioned in the article:

Oil gas field brine is a dominant liquid mineral resource in Sichuan Basin, and its rational development and utilization is of great significance to the national economy. In order to explore the physicochem. properties of brine and provide theor. guidance for the comprehensive utilization of brine, the isothermal solubilities of the ternary systems LiCl – LiBr – H₂O and LiCl – LiBr – CH₃OH at 298 K were determined by employing the isothermal dissolution equilibrium method. Based on the measured composition of the liquid phase, wet solid phase and equilibrium solid phase, isothermal phase diagrams of the two systems at 298 K were drawn. The results show that according to the phase diagram of the ternary system LiCl – LiBr – H₂O at 298 K, there is no single salt and double salt formation, but the crystalline region precipitated by the solid solution occupies all the crystalline space. The phase region is divided by a solubility boundary line into two parts, namely the liquid phase unsaturated region located below the isotherm and the completely mutually soluble solid solution crystallization region above it. Therefore, the two single salts LiCl and LiBr could not be successfully separated with the guidance of this phase diagram. The ternary system LiCl – LiBr – CH₃OH at 298 K has single salt and solid solution formed, but no double salt determined The phase diagram of the ternary system LiCl – LiBr – CH₃OH consists of an invariant point, two isothermal solubility lines, and two crystallization regions precipitated with Li(Cl, Br) and LiCl, resp. Using the phase diagram as a guiding tool for phase separation, LiCl can be acquired by crystallization and filtration operations, but it cannot be achieved for LiBr. In this work, a combination of wet residue method and XRD is used to identify the equilibrium solid phase. Selecting the particle swarm optimization algorithm, the solubility predictions of the ternary systems LiCl – LiBr – H₂O and LiCl – LiBr – CH₃OH at 298 K were achieved through the well-established Pitzer model. The solubility simulation results satisfactorily matched with the exptl. values, indicating that the parameters selected for the simulation have strong applicability. 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

Formation and reactivity of inorganic and organic chloramines and bromamines during oxidative water treatment was written by Heeb, Michele B.;Kristiana, Ina;Trogolo, Daniela;Arey, J. Samuel;von Gunten, Urs. And the article was included in Water Research in 2017.Electric Literature of C6H5ClO2 The following contents are mentioned in the article:

The formation and further reactions of halamines during oxidative water treatment can be relevant for water quality. In this study, we investigated the formation and reactivity of several inorganic and organic halamines (monochloramine, N-chloromethylamine, N-chlorodimethylamine, monobromamine, dibromamine, N-bromomethylamine, N,N-dibromomethylamine, and N-bromodimethylamine) by kinetic experiments, transformation product anal., and quantum chem. computations. Kinetic model simulations were conducted to evaluate the relevance of halamines for various water treatment scenarios. Halamines were quickly formed from the reaction of chlorine and bromine with ammonia or organic amines. Species-specific second-order rate constants for the reaction of chlorine and bromine with ammonia, methyl- and dimethylamine were in the order of 10⁶-10⁸ M^-1s^-1. The formed halamines were found to be reactive towards phenolic compounds, forming halogenated phenols via electrophilic aromatic substitution (phenol and resorcinol) or quinones via electron transfer (catechol and hydroquinone). At near neutral pH, apparent second-order rate constants for these reactions were in the order of 10^-4-10^-1 M^-1s^-1 for chloramines and 10¹-10² M^-1s^-1 for bromamines. Quantum chem. computations were used to determine previously unknown aqueous pK_a values, gas phase bond dissociation energies (BDE) and partial at. charges of the halamines, allowing a better understanding of their reactivities. Kinetic model simulations, based on the results of this study, showed that during chlorination inorganic and organic chloramines are the main halamines formed. However, their further reactions with organic matter are outcompeted kinetically by chlorine. During ozonation, mainly inorganic bromamines are formed, since ozone quickly oxidizes organic amines. The further reactions of bromamine are typically outcompeted by ozone and thus generally of minor importance. The use of peracetic acid for saline ballast water treatment can result in the formation of substantial amounts of bromamines, which can react with dissolved organic matter and contribute to the formation of brominated products. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Electric Literature of C6H5ClO2).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. 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.Electric Literature of C6H5ClO2

Extensive investigation on extraction behaviour of organo-phosphrous based bi-functional ionic liquids for separation of molybdenum (Mo) from spent Co-Mo/Al₂O₃ leach liquor was written by Mohapatra, A. S.;Behera, S. S.;Tripathy, S. K.;Parhi, P. K.;Sanjay, K.. And the article was included in Journal of Molecular Liquids in 2022.Name: N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

The sulfate mediated spent catalyst Co-Mo/Al₂O₃ leached liquor bearing ∼ 6.05 g/L of Mo, 1.75 g/L of Al and 1.44 g/L of Co was subjected to the solvent extraction separation of Mo using noble bi-functional ionic liquids (BILs). Comparative extraction behavior of Mo with two BILs such as quaternary ammonium D2EHPA(R₄ND) and quaternary ammonium Cyanex 272 (R₄NCY) synthesized from Aliquat 336 in combination with D2EHPA and Cyanex 272 was systematically investigated. The purity of synthesized ILs was ascertained from NMR anal. The role of both BILs concentrations appears to be critical on extraction of Mo at acidic pH ranges of the solution with an association of 1 mol each as evident from slope anal. equilibrium study. The Extraction of Mo as H₂MO₄ at optimum solution pH of 2.0 gives rise to achieve a selective separation of Mo in presence of Co and Al as ensured from separation factor (S.F.) value; β_Mo/Co = 5388.8 and 1642.5 for R₄ND and R₄NCY and β_Mo/Al = 1309.2 and 13522.1 for R₄ND and R₄NCY resp. The extraction yield of Mo with ILs was enhanced while increasing the temperature of the solution as indicated from the pos. ΔH (+40.26 KJ/mol & 73.27 β_Mo/Co = 5388.8 and 1642.5 for R₄ND and R₄NCY and β_Mo/Al = 1309.2 and 13522.1 for R₄ND and R₄NCY) values. The diluents effect on Mo extraction was consistent with either of the ILs and they follows the order as n-Hexane > Tolune > Kerosene > Benzene > Xylene. The Mc-Cabe Thiele plot constructed at A: O = 5:1 has predicted 2 stages using 0.6 M each of R₄ND and/or R₄NCY and later it was validated from CCS leading to attain>99.9 % Mo extraction The extraction behavior of R₄NCY was efficient and effective on clean separation of Mo over R₄ND at the studied exptl. condition. Stripping of Mo-loaded-R₄NCY by NH₄OH was promising with the Mo enrichment up to 3 times with generation of purified stripped bearing 90.71 g/L of Mo. FTIR characteristic peak of R₄ND and R₄NCY before and after extraction confirms in support of the Mo extraction with ILs.

Disinfectant and antimicrobial susceptibility studies of the foodborne pathogen Campylobacter jejuni isolated from the litter of broiler chicken houses was written by Beier, Ross C.;Byrd, J. Allen;Andrews, Kathleen;Caldwell, Denise;Crippen, Tawni L.;Anderson, Robin C.;Nisbet, David J.. And the article was included in Poultry Science in 2021.SDS of cas: 122-18-9 The following contents are mentioned in the article:

Foodborne illness is an ongoing problem worldwide and is caused by bacteria that invade the food chain from the farm, slaughter house, restaurant or grocery, or in the home and can be controlled by strategies using biocides (antiseptics and disinfectants). Susceptibility profiles were determined for 96 Campylobacter jejuni strains obtained in 2011-2012 from broiler chicken house environments to antimicrobials and disinfectants as per the methods of the Clin. and Laboratory Standards Institute and TREK Diagnostics using CAMPY AST Campylobacter plates. Low prevalence of antimicrobial resistance was observed in C. jejuni strains to tetracycline (TET; 21.9%), ciprofloxacin (CIP; 13.5%), and nalidixic acid (NAL; 12.5%). The resistance profiles had a maximum of 3 antimicrobials, CIP-NAL-TET, with TET being the main profile observed No cross-resistance was observed between antimicrobials and disinfectants. The C. jejuni strains (99%) were resistant to triclosan, 32% were resistant to chlorhexidine, and they all were susceptible to benzalkonium chloride. The strains had low-level min. inhibitory concentrations (MICs) to the disinfectants P-128, Food Service Sanitizer, F-25 Sanitizer, Final Step 512 Sanitizer, OdoBan, dioctyldimethylammmonium chloride, didecyldimethylammonium chloride (C10AC), benzyldimethyldodecylammonium chloride (C12BAC), and benzyldimethyltetradecylammonium chloride (C14BAC). Intermediate MICs against DC&R, cetylpyridinium bromide hydrate, hexadecylpyridinium chloride, ethylhexadecyldimethylammonium bromide, and hexadecyltrimethylammonium bromide with elevated intermediate MICs against Tek-Trol, benzyldimethylhexadecylammonium chloride, tris(hydroxylmethyl)nitromethane (THN), and formaldehyde. The highest MIC were obtained for povidone-iodine. The components THN and the benzylammonium chlorides C12BAC and C14BAC were responsible for the inhibition by DC&R. The components C10AC and C12BAC may act synergistically causing inhibition of C. jejuni by the disinfectant P-128. The formaldehyde component in DC&R was not effective against C. jejuni compared with the ammonium chloride components. Its use in disinfectants may result in addnl. unnecessary chems. in the environment. Didecyldimethylammonium chloride is the most effective ammonium chloride component against C. jejuni. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9SDS of cas: 122-18-9).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) 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. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.SDS of cas: 122-18-9

FKN/CX3CR1 axis facilitates migraine-Like behaviour by activating thalamic-cortical network microglia in status epilepticus model rats was written by Zhou, Yanjie;Zhang, Lily;Hao, Yuyan;Yang, Liu;Fan, Shanghua;Xiao, Zheman. And the article was included in Journal of Headache and Pain in 2022.Synthetic Route of ClLi The following contents are mentioned in the article:

The incidence of migraines is higher among individuals with epilepsy than in healthy individuals, and these two diseases are thought to shared pathophysiol. mechanisms. Excitation/inhibition imbalance plays an essential role in the comorbidity of epilepsy and migraine. Microglial activation is crucial for abnormal neuronal signal transmission. However, it remains unclear whether and how microglia are activated and their role in comorbidities after being activated. This study aimed to explore the characteristics and mechanism of microglial activation after seizures and their effect on migraine. Model rats of status epilepticus (SE) induced by i.p. injection of lithium chloride (LiCl)-pilocarpine and migraine induced by repeated dural injections of inflammatory soup (IS) were generated, and mol. and histopathol. evidence of the microglial activation targets of fractalkine (FKN) signalling were examined HT22-BV2 transwell coculture assays were used to explore the interaction between neurons and microglia. LPS (a microglial agonist) and FKN stimulation of BV2 microglial cells were used to evaluate changes in BDNF levels after microglial activation. Microglia were specifically hyperplastic and activated in the temporal lobe cortex, thalamus, and spinal trigeminal nucleus caudalis (sp5c), accompanied by the upregulation of FKN and CX3CR1 four days after seizures. Moreover, SE-induced increases in nociceptive behavior and FKN/CX3CR1 axis expression in migraine model rats. AZD8797 (a CX3CR1 inhibitor) prevented the worsening of hyperalgesia and microglial activation in migraine model rats after seizures, while FKN infusion in migraine model rats exacerbated hyperalgesia and microglial activation associated with BDNF-Trkb signalling. Furthermore, in neuron-microglia cocultures, microglial activation and FKN/CX3CR1/BDNF/iba1 expression were increased compared with those in microglial cultures alone. Activating microglia with LPS and FKN increased BDNF synthesis in BV2 microglia. Our results indicated that epilepsy facilitated migraine through FKN/CX3CR1 axis-mediated microglial activation in the cortex/thalamus/sp5c, which was accompanied by BDNF release. Blocking the FKN/CX3CR1 axis and microglial activation are potential therapeutic strategies for preventing and treating migraine in patients with epilepsy.

PVDF-HFP based polymer inclusion membranes containing Cyphos IL 101 and Aliquat 336 for the removal of Cr(VI) from sulfate solutions was written by Bahrami, Salar;Yaftian, Mohammad Reza;Najvak, Pourya;Dolatyari, Leila;Shayani-Jam, Hassan;Kolev, Spas D.. And the article was included in Separation and Purification Technology in 2020.Quality Control of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) was used for the preparation of polymer inclusion membranes (PIMs) containing trihexyltetradecylphosphonium chloride (Cyphos IL 101) or trioctylmethylammonium chloride (Aliquat 336) for the removal of Cr(VI) from sulfate solutions PIMs containing 50 wt% of Cyphos IL 101 or Aliquat 336, with corresponding thicknesses of 54 ± 7 or 48 ± 9μm, were transparent and mech. stable. SEM, at. force microscopy, thermogravimetric anal., stress-strain anal., and contact angle measurements were used for characterizing PIM surface morphol., thermal and mech. properties. The extraction experiments were performed by immersing a circular PIM segment (3.5 cm in diameter) in a 50 mL sulfate solution containing 2.0 x 10^-4 mol L^-1 of Cr(VI). The optimum conditions with respect to pH and sulfate concentration were 1.2 and 0.045 mol L^-1, resp. The results indicated a higher extraction rate of Cr(VI) by the PIM containing Cyphos IL 101 in comparison with that achieved by the Aliquat 336 based PIM. Anal. of the extraction data confirmed that the main extracted species into both PIMs was HCrO^–₄. A variety of stripping reagents were tested and best results were obtained with 1.0 mol L^-1 NaNO₃ which allowed efficient back-extraction of Cr(VI) from the loaded PIMs containing Cyphos IL 101 or Aliquat 336. The extraction capacity of the Cyphos IL 101 and Aliquat 336 based PIM was 71 mg and 70 mg of Cr per 1 g of membrane and they could be reused for 16 and 6 consecutive extraction/back-extraction cycles, resp. It was found that the mass loss of the Cyphos IL 101 PIMs in these experiments was significantly lower than that observed for the Aliquat 336 based PIMs. These results illustrated the excellent stability of the Cyphos IL 101 based PIM. Both Cyphos IL 101 and Aliquat 336 based PIMs did not experience interference in the extraction of Cr(VI) by other common cations. The Cyphos IL 101 based PIM extracted selectively Cr(VI) in the presence of up to 500 fold excess of nitrate and chloride anions, while this selectivity was limited to 10 fold for the Aliquat 336 based PIM. The potential of both PIMs for practical applications was demonstrated with the removal of Cr(VI) from well water and industrial wastewater.

IR-spectral data suggested a monobasic tridentate binding mode for the ligand towards the metal ions within mono-nuclear complexes. Ligand field transitions as well as magnetic susceptibility, orient strongly for square-planer geometry with Ni(II) and Cu(II) complexes, while octahedral geometry for Co(II) complex. Mass spectroscopy and TGA were performed for complexes to assess on their mol. formulas and the mol. ion peak is attributing to dehydrating complex (M⁺-nH₂O). TEM, EDX and XRD were carried out to indicate morphol., crystallinity and chem. composition of tested complexes. The crystal data estimated, reflect nanometer sizes of studied complexes. DFT method was utilized to obtain optimized structures under 6-31G and LANL2DZ basis sets. Hirshfeld surface properties were estimated for 3D crystal models of complexes, to put view about the contact strength within crystal packing. 2D-fingerprint plots for elemental contribution, clarify the effective contribution of O and H atoms in surface contact between crystals. Cu (II) complex showed greatest potent cytotoxic profile against MCF-7, HepG2 and PC-3 carcinoma cell lines, by IC₅₀s 2.2, 2.6 and 2.1 μg, resp. High killing rate for tumor cells was observed with an early apoptotic pathway under treatment with all compounds Also, Cu(II) complex stimulates necrosis killing effect on prostate (PC-3) and breast (MCF-7) cancer cells. Ligand-based pharmacophore methodol., was performed to indicate the most suitable contact sites in compounds towards 1z8l & 3rcd proteins. The search hits several compounds reach 3,732,214 hits and a closer 3D-fingerprint drug model was obtained. MOE docking was performed for most compounds to explain all interaction features through such simulation process. Best docking scores were recorded with HL-3rcd, Co(II)complex-1z8l, Co(II) complex-3rcd and Cu(II) complex-3rcd by values of -60,628, -6.1447, -6.055 and -6.0626, resp. Amino acid residues that contributing in allosteric binding were clearly categorized. Finally in-silico approach confirms the superiority of Co(II)-L, Cu(II)-L and free thiophene derivative in controlling human cancer cells, which agree with in vitro results. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Application of 638-07-3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) 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. 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.Application of 638-07-3
