E.;Iskander, Abanob A. F.;Hassan, Hammed H. A. M.. And the article was included in Journal of Macromolecular Science in 2017.Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:

We prepared two series of nanosized polymers containing s-triazine moiety by reactions of newly prepared substituted diacids chlorides derived from 2-anilino-4,6-di-(phenoxy)- and 2-(N-1-naphthylamine)-4,6-di-(phenoxy)-s-triazines with a number of com. diamines. The polymers were carefully characterized by different techniques including IR, UV, fluorescent emission, elemental and thermal analyses and SEM (SEM). The SEM images indicated that most of the polyamides were organized as well defined nano sized spheres, but in certain derivatives small amount of aggregated nanospheres was also observed Structure-property correlations based on a single or more interchange proved to be feasible. The polymers exhibited high thermal behavior and, based on the produced char yields, the limiting oxygen index (LOI) indicated that a dozen polymers were classified as “slow burning polymers” while the other dozen polymers were “self-extinguishing polymers”. Polymers derived from sym. diamine exhibited better thermal stability than those containing asym. diamines. Interestingly, while the naphthyl/phenyl interchange has no influence on the thermal properties in some cases, however, dramatic improvements were noticed in many other cases. Obviously, the pyridine/phenylene interchange has no influence on the thermal properties of the addressed polymers. The polymers exhibited emissions ranging from blue to orange wavelength depending on the nature of the signaling unit. While the introduction of a naphthyl moiety has no significant influence on the electronic properties in some cases, however, the interchange led to either appreciable red-shifted absorptions or disrupt the conjugation and thus blue-shifted absorptions in other analogs. This result enables such polymers as good candidates in different technol. applications. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).

Separation of Re(VII) from Mo(VI) using biomaterial-based ionic gel adsorbents: Extractive adsorption enrichment of Re and surface blocking of Mo was written by Li, Wenjing;Dong, Xuelin;Zhu, Lihua;Tang, Heqing. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020.Formula: C25H54ClN The following contents are mentioned in the article:

It is urgently needed to develop highly efficient and selective adsorbents for enrichment and separation of Re(VII) from Mo(VI) to obtain metallic rhenium. By tuning cross-link of chitosan, ionic gel capsules (CSN) were prepared, which had a core-shell structure and wrapped N263 (Me trioctyl ammonium chloride) as an extractant. After being characterized, the CSN capsules were used as a green adsorbent for separation of ReO^–₄ from MoO^2-₄. It was found that the gel yielded good adsorption capacities for Re(VII) in a wide pH range from pH 2 to 12. The adsorption of Re(VII) on the gel followed the Langmuir model, exhibiting a maximum adsorption capacity of 222 mg g^-1 for Re. The adsorbent showed good adsorption capacities for Mo(VI) at pH < 2, but little at pH > 3.5. Therefore, the enrichment and separation of Re(VII) from Mo(VI) could be easily achieved by using the gel adsorbent in a wide pH range from 4 to 12, showing a separation factor β_Re/Mo with values of 10³-5 × 10⁴. A mechanism was proposed for the selective adsorption of Re(VII). The extractant N263 wrapped in the capsule core provides excellent extractive adsorption ability for Re(VII) through ion association extraction, generating ion association complex R₄N⁺•ReO^–₄ in the adsorbent. The gel shell was composed of cross-linked chitosan induced by sodium tripolyphosphate, and functioned as a blocking layer for the adsorption of Mo(VI), being possibly related to a special interaction between Mo and P as observed in the formation of phosphorus molybdenum heteropolyacid and/or the crosslinking with Mo and chitosan. The CSN gel was successfully applied to sep. ReO^–₄ from a practical alk. solution This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Formula: C25H54ClN).

A critical challenge in the enrichment of active ingredients in natural medicines is the design of adsorbents with high selectivity and adsorption capacity. Covalent organic frameworks (COFs), which have adjustable pores and high sp. surface areas, could be effective as adsorbents for active ingredients. This study used an environmentally friendly deep eutectic solvent (DES) instead of organic solvents as the reaction solvent, and high-crystallinity COF-DES was successfully prepared The COF-DES fabricated using 1,3,5-tris(4-aminophenyl)benzene and 2,5-dihydroxyterephthalaldehyde as building blocks showed good dispersibility, large surface area (444.56 m²·g^-1), and suitable pore size (25.9 Å). Owing to its unique structure and functional group properties, COF-DES can prevent interferences from other compounds such as alkaloids, resulting in outstanding selective adsorption performance for flavonoids. Furthermore, under optimized adsorption conditions, the adsorption effects of the COF-DES on flavonoids were much better than those of the effects of macroporous resins, indicating the potential of the COF-DES as a selective adsorbent for flavonoids. Finally, a flavonoid-possessing rich natural medicine, Abelmoschus manihot (Linn.) Medicus flower, was used as a sample to study the application potential of the COF-DES. The results showed that the COF-DES had good adsorption and selection capability for flavonoids in actual samples. Moreover, compared with solid-phase extraction (SPE) columns based on macroporous resins, a COF-DES based SPE column showed superior adsorption performance for an actual complex sample, indicating the potential to COF-DES as an effective adsorbent alternative to macroporous resins. Addnl., the COF-DES had great com. value as an adsorbent for SPE flavonoid columns.

Chlorophylls Extraction from Spinach Leaves Using Aqueous Solutions of Surface-Active Ionic Liquids was written by Ferreira, Ana M.;Leite, Ana Claudia;Coutinho, Joao A. P.;Freire, Mara G.. And the article was included in Sustainable Chemistry in 2021.SDS of cas: 75-57-0 The following contents are mentioned in the article:

Chlorophylls and their derivatives have been extensively studied due to their unique and valuable properties, including their anti-mutagenic and anti-carcinogenic features. Nevertheless, high-purity-level chlorophylls extracted from natural sources are quite expensive because the methods used for their extraction have low selectivity and result in low yields. This study aimed to develop a “greener” and cost-effective technol. for the extraction of chlorophylls from biomass using aqueous solutions of ionic liquids (ILs). Several aqueous solutions of ILs, with hydrotropic and surface-active effects were evaluated, demonstrating that aqueous solutions of surface-active ILs are enhanced solvents for the extraction of chlorophylls from spinach leaves. Operating conditions, such as the IL concentration and solid-liquid ratio, were optimized by a response surface method. Outstanding extraction yields (0.104 and 0.022 weight% for chlorophyll a and b, resp., obtained simultaneously) and selectivity (chlorophyll a/b ratio of 4.79) were obtained with aqueous solutions of hexadecylpyridinium chloride ([C16py]Cl) at moderate conditions of temperature and time. These extraction yields are similar to those obtained with pure ethanol. However, the chlorophyll a/b ratio achieved with the IL aqueous solution is higher than with pure ethanol (3.92), reinforcing the higher selectivity afforded by IL aqueous solutions as viable replacements to volatile organic compounds and allowing the obtainment of more pure compounds Finally, the recovery and reuse of the solvent were evaluated by using a back-extraction step of chlorophylls using Et acetate. The results disclosed here bring new perspectives into the design of new approaches for the selective extraction of chlorophylls from biomass using aqueous solutions of surface-active ILs. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways.

Safety and Tolerability of Overdosed Artificial Tears by Abraded Rabbit Corneas was written by Daull, Philippe;Raymond, Elisabeth;Feraille, Laurence;Garrigue, Jean-Sebastien. And the article was included in Journal of Ocular Pharmacology and Therapeutics in 2018.SDS of cas: 122-18-9 The following contents are mentioned in the article:

Purpose: Preservative-free cationic emulsion-based artificial tear (AT) is an innovative eye drop based on the Novasorb technol. with cetalkonium chloride (CKC) as the cationic agent. The cationic emulsion Cationorm is designed for the management of mild-to-moderate dry eye disease (DED) patients that present cornea epithelium alterations. The aim of the present study was to evaluate the safety and tolerability of overdosed ATs by altered corneal epithelium in vivo and assess the usefulness of the ex vivo eye irritation test (EVEIT) as a predictive alternate toxicity test method. Methods: The exptl. procedure, treatment duration, and instillation frequency closely mimic in vivo the ex vivo protocol described by Pinheiro et al. and discussed in the section of this article. Two to 3-mo-old female New Zealand white rabbits, n = 6 per group, were treated with ATs (21 instillations/day over 3 days) following corneal abrasion. Corneal fluorescein staining, in vivo confocal microscopy (IVCM), and slit lamp examinations were performed to assess corneal epithelium recovery and the ocular tolerability of the overdosed ATs. Results: All abraded eyes experienced almost complete epithelium recovery within 3 days following treatments with Cationorm, Optive, Vismed, and Saline. Benzalkonium chloride (BAK, 0.02%) treatment resulted in 82.4% reepithelialization. IVCM data illustrated corneal epithelium normal recovery. Acute local tolerability of the overdosed ATs was confirmed using Draize and McDonald-Shadduck′s test scales. Conclusions: The different ATs were demonstrated to be well tolerated by abraded corneas in vivo, and the extreme overdosing regimen did not hamper the wound healing process of the rabbit eye in comparison to saline. These data did not confirm the ones obtained with the nonvalidated ex vivo eye irritation test. 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).

Cellulose polymers with multidentate chelating functionalities that have high efficiency for toxic metal ions present in water were designed, synthesized, and analyzed. The synthesis was carried out by reacting microcrystalline cellulose extracted from the solid waste of the olive industry with tert-Bu acetoacetate (Cell-AA), produced cellulose with β-ketoester functionality was then reacted with aniline and the amino acid glycine to produce Cell-β-AN and Cell-β-GL, resp. The adsorption efficiency of the three polymers toward Pb(II) and various toxic metal ions present in sewage was evaluated as a function of adsorbent dose, time, temperature, pH value, and initial ion concentration to determine optimum adsorption conditions. The three polymers showed excellent efficiency toward about 20 metal ions present in a sewage sample collected from the sewer. The adsorption process follows the Langmuir adsorption isotherm model with a second-order of adsorption rate, the calculated qe values (2.675, 15.252, 20.856 mg/g) were close to the exptl. qe values (2.133, 13.91, 18.786 mg/g) for the three polymers Cell-AA, Cell-β-AG and Cell-β-AN, resp. Mol. Dynamic (MD) and Monte Carlo (MC) simulations were performed on the three polymers complexed with Pb(II). The waste material of the olive industry was used as a precursor for making the target cellulose polymers with β-Amino Ester Pendant Group. The polymer was characterized by SEM, proton NMR, TGA, and FT-IR spectroscopy. The efficacy of adsorption was quant. for metal ions present in a real sample of wastewater and the efficiency didn′t drop even after 7 cycles of use. The results indicate the existence of strong complexation. The thermodn. study results showed a spontaneous bonding between of Pb(II) and the polymers pendant groups expressed by the neg. value of the Gibbs free energy.

Dual-functional gas hydrate inhibition of tetramethylammonium chloride for carbon dioxide-methane mixed gas systems was written by Moujdin, Iqbal Ahmed;Khan, Muhammad Saad;Lal, Bhajan;Abulkhair, Hani Abdullah;Alsaiari, Abdulmohsen. And the article was included in Fuel in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

The present work deals with evaluating the dual-functional gas hydrate impact of tetramethylammonium chloride (TMACl) in the presence of different CO₂-CH₄ content mixed gas hydrate systems (30%CO₂+ 70%CH₄ , 50%CO₂+ 50%CH₄, and 70%CO₂+ 30%CH₄). A custom-made high-pressure gas hydrate reactor was used to acquire the temperature-pressure loops for the studied systems in the absence/presence of different concentrations of aqueous TMACl solutions via T-Cycle and isochoric constant cooling method for both THI and KHI investigations, resp. The electrolyte-based thermodn. model was also applied to validate the obtained HLwVE results for all the studied systems. The obtained results revealed that TMACl acts dual-functional (thermodn. and kinetic) hydrate inhibitor for high CO₂ content gas systems. The increased concentration of TMACl induces more shifts in HLwVE data with maximum variation attained at10 wt% concentration up to 1.46 K for a high CO₂ content methane system owing to the increased hydrogen bonding ability of TMACl. Moreover, TMACl delayed the hydrate formation up to 1.4 and1.5 folds for 274.0 and 277.0 K conditions for high CO₂ content mixed gas systems. Moreover, the applied electrolyte-based model could predict the HLwVE data of TMACl in the presence of a mixed gas system within the AAE value of 0.1% for all the studied mixed gas systems. Furthermore, the KHI performance of TMACl was also compared with com. inhibitor, i.e., polyvinyl pyrrolidone (PVP), and obtained comparable results. Therefore, the acquired dual-functional results (THI = 1.46 K, KHI = 1.5-fold delay) signpost that TMACl can efficiently work as a potential dual-functional hydrate inhibitor for CO₂ enriched mixed gas systems. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Category: chlorides-buliding-blocks).

How does coal interact with organic groups in an aqueous solution was written by Xu, Wennan;Li, Yuxin;Liu, Xin;Zhao, Yining;Li, Rui;Li, Hongliang. And the article was included in Fuel in 2022.Formula: C25H46ClN The following contents are mentioned in the article:

Interactions between coal matrix and organics are vital for adsorption, surfactant adsorption on lignite, and solid-liquid separation of coal slurry. Herein, for studying the interaction between hydrophobic surface (coal surface) and small mols. (organics), we measured interactions between organics [nitro and Ph, pyridine, Ph, alkyl chain (hexyl) or cycloalkyl (hexyl)] and the coal matrix (liptinite or inertinite) using at. force microscopy. The strength of interaction followed the order: nitro and Ph > pyridine > Ph >alkyl chain (hexyl)> cycloalkyl (hexyl), and liptinite > inertinite. The liptinite has a greater hydrophobicity than inertinite, the greater the attraction force. The lignite surface and coal slurry were modified in an aqueous solution using five surfactants (dodecyl tri-Me ammonium chloride, DTAC; hexadecyl tri-Me ammonium chloride, CTAC; octadecyl tri-Me ammonium chloride, STAC; hexadecyl di-Me benzyl ammonium chloride, HDBAC; and cetyl pyridine chloride, CPC). Subsequently, the moisture adsorption on treated lignite coal surface and the sedimentation of the treated tails was compared to characterize hydrophobic modifications which showed the order of CTAC > HDBAC > DTAC > CPC > STAC. Thus, the interaction between coal surface and organics needs to consider two rules: 1) The desolvation or the hydrophobic property of the coal surface; 2) The VDW force of the organics The nature of the difference between rules Number 1 and 2 is that with the size of hydrophobic mols. increased to a surface, the H-bond structure between water mols. in the around would change a lot, which formats great hydrophobic property or desolvation. Interaction between organic reagents and coal reveals the mechanism of restraining moisture reabsorption of lignite and solid-liquid separation of coal slurry by organics This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Formula: C25H46ClN).

Cyclosporine A Nanosuspensions for Ophthalmic Delivery: A Comparative Study between Cationic Nanoparticles and Drug-Core Mucus Penetrating Nanoparticles was written by Yan, Rong;Xu, Lai;Wang, Qiuhe;Wu, Zheng;Zhang, Hua;Gan, Li. And the article was included in Molecular Pharmaceutics in 2021.COA of Formula: C25H46ClN The following contents are mentioned in the article:

The effect of mucin on ocular bioavailability depends on the extent to which it acts as a barrier or retention site. Mucus penetrating particles (MPPs) can evade the mucus entrapment and associated rapid clearance, but cationic nanoparticles have high adhesion to the mucosa. Both formulations can prolong the drug residence time on the surface of the eyes. The purpose of this work is to compare the effects of mucoadhesion of cationic nanoparticles and mucous permeability of MPPs on ocular bioavailability. Cationic nanosuspensions and drug-core MPP nanosuspensions were developed using the anti-solvent precipitation method. The results of X-ray diffraction revealed that CsA was amorphous. In vitro mucoadhesion evaluation demonstrated that cationic nanosuspensions enhanced the interaction with pig mucin about 5.0-6.0 fold compared to drug-core MPP nanosuspensions. A mucus permeation study by the transwell diffusion system showed that the P_app values of drug-core MPP nanosuspensions were 5.0-10.0 times higher than those of cationic nanosuspensions. In vivo ocular bioavailability evaluation of those CsA formulations was conducted in rabbits using a conventional nanosuspension as a comparison. The CsA concentrations in the cornea following the administration of a cationic nanosuspension and a drug-core MPP nanosuspension were 13,641.10 ng/g and 11,436.07 ng/g, resp., significantly higher than that of the conventional nanosuspension (8310.762 ng/g). The results showed that both the cationic and MPP nanosuspensions were able to deliver CsA to anterior ocular tissues in effective therapeutic concentrations (10-20μg/g) with topical drop instillation. The cationic nanosuspension could achieve relatively higher bioavailability than the MPP nanosuspension. The cationic nanosuspension would be a promising ocular drug delivery system.

A facile and low-cost wet-chemistry artificial interface engineering for garnet-based solid-state Li metal batteries was written by Leng, Jin;Liang, Hongmei;Wang, Huaying;Xiao, Zunqiu;Wang, Shitong;Zhang, Zhongtai;Tang, Zilong. And the article was included in Nano Energy in 2022.Name: Lithium chloride The following contents are mentioned in the article:

Solid-state lithium metal batteries (SSLMBs) have been widely predicted as an “enabler” for the next-generation high-energy-d. batteries. To perform this goal, both solid electrolytes (SEs) and metallic Li anodes are the keys. Li-rich garnet SEs exhibit many unique advantages for enabling SSLMBs, such as high Li-ion conductivity, superior mech., chem. and electrochem. properties. However, the garnet-based SSLMBs suffer from intractable interfacial problems including poor-contact-induced high interfacial impedance and dendrite-induced fast short circuit, which greatly hinder their practical application. In this work, a facile and low-cost artificial interface engineering is proposed to improve Li/SEs interface. Benefitted from the superior wettability of isopropanol InCl₃ solution on the Li₆.₄La₃Zr₁.₄Ta₀.₆O₁₂ (LLZTO) surface, a homogeneous and tightly-adhering lithiophilic interface consisting of InLix and LiCl is efficiently constructed. As a result, the interface impedance was decreased from 189 to 10 Ω, and the critical c.d. for the LLZTO is increased from 0.2 mA cm^-2 to 0.7 mA cm^-2. The Li/Li sym. cells can work stably above 4000 h at a c.d. of 0.2 mA cm^-2. At a higher c.d. of 0.45 mA cm^-2, no obvious dendritic Li proliferation and interfacial contact failure is observed after cycling for more than 1000 h. The full cells with LiFePO4 as cathode exhibit a superior electrochem. performance with a reversible capacity of 127 mAh g^-1 at 0.5 C after 475 cycles, and a rate capability of 101 mAh g^-1 at 1 C. This effective, simple and economical wet-chem. strategy for constructing Li/SEs artificial interface may provide an alternative route for solve the interfacial issues of other SSLMBs.
