Indole is an important industrial substance that can be derived from coal tar. However, traditional acid-base separation method causes serious environmental problems. In this research, the indole separation abilities of different quaternary ammonium salts (QASs) from nitrogen-containing compounds and azeotrope systems were explored. Series of QASs with different substituent groups were investigated through examining the extraction efficiency, including tetraethylammonium chloride (TEAC), betaine hydrochloride (BHC), tetramethylammonium chloride (TMAC), tetraethylammonium bromide (TEAB), and benzyl trimethylammonium chloride (BTMAC). Among them, TEAC was found to be able to form deep eutectic solvents (DES) with indole. The effects of different exptl. conditions such as extraction time, extraction temperature, and mole ratio were studied and optimum extraction conditions were obtained. Quantum calculation was employed to explore the extraction mechanism. σ-profiles and σ-surfaces of QASs ions and related compounds were derived from COSMO database and analyzed to explore their interaction forces. The interaction energies between QASs ions and related compounds composed by misfit, van der Waals (VDW) and hydrogen bond (HB) were calculated based on COSMO-RS theory. Using these methods, the separation possibilities of indole through DES formation by QASs can be speculated. Ultimately, the bond lengths and interaction energies between QASs and indole were calculated concretely using Material Studio. The above quantum calculation proved the existence of hydrogen bonds between indole and QASs and the deductions obtained from quantum calculation were consistent with the exptl. results. According to the above anal., the separation method through DES formation was proved to have a relatively high requirement for extractant. The mechanism research in this article provided essential reference for the selection of applicable extractant, and the prediction of the separation efficiency. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0COA of Formula: C4H12ClN).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides.

Quaternary ammonium compounds with multiple cationic moieties (multiQACs) provide antimicrobial activity against Campylobacter jejuni was written by Gunther, Nereus W. IV;Abdul-Wakeel, Aisha;Reichenberger, Erin R.;Al-Khalifa, Saleh;Minbiole, Kevin P. C.. And the article was included in Food Control in 2018.Computed Properties of C25H46ClN The following contents are mentioned in the article:

Recently developed quaternary ammonium compounds (QACs) possessing multiple cationic moieties, referred to as multiQACs, were tested with strains of Campylobacter jejuni to determine their potential as antimicrobial compounds against this important foodborne pathogen. Eight multiQACs were tested against a cocktail of six C. jejuni strains isolated from environmental and clin. sources. The resulting reductions in C. jejuni numbers mediated by the multiQACs were compared to the reductions produced by the application of four com. available QACs, each of which bears a single cation. Multiple concentrations and exposure times were utilized for all compounds The compounds which yielded the maximum C. jejuni reductions at the lowest concentrations and applied over the shortest exposure times were judged to be the most successful. Of the eight multiQACs investigated, four demonstrated reductions in C. jejuni numbers superior to the com. QACs; these four are biscationic, and two of them bear an addnl. uncharged nitrogen atom. The remaining four multiQACs, which contain three or four cations, did not produce reductions in bacterial numbers comparable to com. QACs in the timeframes tested. At the intermediary compound concentration (0.05 mM) and exposure time (5 min) the most effective multiQACs (PQ-12,12 and 12(3)0(3)12) on average killed over 99% of the Campylobacter cells present while the best com. compound at those parameters (cetyl pyridinium chloride, CPC) only killed on average 84.56% of the Campylobacter cells. At the highest compound concentration tested (0.1 mM) and shortest exposure time (1 min), the same two biscationic multiQACs averaged mean percent reductions of Campylobacter cell numbers around 99.5% while CPC at the same concentration/exposure only managed a percent reduction of 91.3%. The biscationic multiQACs demonstrate the potential for providing a new group of antimicrobial compounds superior to current com. available QACs in their effectiveness against C. jejuni. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Computed Properties of C25H46ClN).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) 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 C25H46ClN

The effect of surface modification of gold nanotriangles for surface-enhanced raman scattering performance was written by Koetz, Joachim. And the article was included in Nanomaterials in 2020.Synthetic Route of C25H46ClN The following contents are mentioned in the article:

A review. A surface modification of ultraflat gold nanotriangles (gold nanotriangles) with different shaped nanoparticles is of special relevance for surface-enhanced Raman scattering (SERS) and the photo-catalytic activity of plasmonic substrates. Therefore, different approaches are used to verify the flat platelet morphol. of the gold nanotriangles by oriented overgrowth with metal nanoparticles. The most important part for the morphol. transformation of the gold nanotriangles is the coating layer, containing surfactants or polymers. By using well established gold nanotriangles stabilized by a dioctyl sodium sulfosuccinate bilayer, different strategies of surface modification with noble metal nanoparticles are possible. On the one hand undulated superstructures were synthesized by in situ growth of hemispherical gold nanoparticles in the polyethyleneimine (PEI)-coated AOT bilayer of the AuNTs. On the other hand spiked gold nanotriangles were obtained by a direct reduction of Au³⁺ ions in the dioctyl sodium sulfosuccinate double layer in presence of silver ions and ascorbic acid as reducing agent. Addnl., crumble topping of the smooth gold nanotriangles can be realized after an exchange of the dioctyl sodium sulfosuccinate bilayer by hyaluronic acid, followed by a silver-ion mediated reduction with ascorbic acid. Furthermore, a decoration with silver nanoparticles after coating the dioctyl sodium sulfosuccinate bilayer with the cationic surfactant benzylhexadecyldimethylammonium chloride (BDAC) can be realized. In that case the UV-absorption of the undulated Au@Ag nanoplatelets can be tuned depending on the degree of decoration with silver nanoparticles. Comparing the Raman scattering data for the plasmon driven dimerization of 4-nitrothiophenol (4-NTP) to 4,4′-dimercaptoazobenzene (DMAB) one can conclude that the most important effect of surface modification with a 75 times higher enhancement factor in SERS experiments becomes available by decoration with gold spikes. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Synthetic Route of C25H46ClN).

The hydrophobic and the hydrophilic rims in the active site of human carbonic anhydrase IX (hCA IX) which as well contains a zinc ion as part of the catalytic core, were simultaneously matched to design and synthesize potent and selective inhibitors using a dual-tail approach. Seventeen new compounds, 5a-q, were designed to have the benzenesulfonamide moiety as a zinc binding group. In addition, N-substituted hydrazone and N-Ph fragments were chosen as the hydrophilic and hydrophobic parts, resp. to achieve favorable interactions with the corresponding halves of the active site. All synthesized compounds successfully suppressed the CA IX, with IC50 values in nanomolar range from 13.3 to 259 nM. Compounds, 5h, 5c, 5m, 5e, and 5k were the top-five compounds efficiently inhibited the tumor-related CA IX isoform in the low nanomolar range (KI = 13.3, 22.6, 25.8, 26.9 and 27.2 nM, resp.). The target compounds 5a-q developed remarkable selectivity toward the tumor-associated isoforms (hCA IX and XII) over the off-target isoforms (hCA I and II). Furthermore, they were assessed for their anti-proliferative activity, according to US-NCI protocol, against a panel of fifty-nine cancer cell lines. Compounds 5d, 5k and 5o were passed the criteria for activity and scheduled automatically for evaluation at five concentrations with 10-fold dilutions Compound 5k exhibited significant in vitro anticancer activity with GI50-MID; 8.68 μM compared to compounds 5d and 5o with GI50-MID; 25.76 μM and 34.97 μM resp. The most selective compounds 5h and 5k were further screened for their in vitro cytotoxic activity against SK-MEL-5, HCC-2998 and RXF 393 cancer cell lines under hypoxic conditions. Furthermore, 5k was screened for cell cycle disturbance, apoptosis induction and intracellular reactive oxygen species (ROS) production in SK-MEL-5 cancer cells. Finally, mol. docking studies were performed to gain insights for the plausible binding interactions and affinities for selected compounds within hCA IX active site.

Biphasic Bioelectrocatalytic Synthesis of Chiral β-Hydroxy Nitriles was written by Dong, Fangyuan;Chen, Hui;Malapit, Christian A.;Prater, Matthew B.;Li, Min;Yuan, Mengwei;Lim, Koun;Minteer, Shelley D.. And the article was included in Journal of the American Chemical Society in 2020.Electric Literature of C6H9ClO3 The following contents are mentioned in the article:

Two obstacles limit the application of oxidoreductase-based asym. synthesis. One is the consumption of high stoichiometric amounts of reduced cofactor. The other is the low solubility of organic substrates, intermediates, and products in the aqueous phase. In order to address these two obstacles to oxidoreductase-based asym. synthesis, a biphasic bioelectrocatalytic system was constructed and applied. In this study, the preparation of chiral β-hydroxy nitriles catalyzed by alc. dehydrogenase (AdhS) and halohydrin dehalogenase (HHDH) was investigated as a model bioelectrosynthesis, since they are high-value intermediates in statin synthesis. Diaphorase (DH) was immobilized by a cobaltocene-modified poly(allylamine) redox polymer on the electrode surface (DH/Cc-PAA bioelectrode) to achieve effective bioelectrocatalytic NADH regeneration. Since AdhS is a NAD-dependent dehydrogenase, the diaphorase-modified biocathode was used to regenerate NADH to support the conversion from Et 4-chloroacetoacetate (COBE) to Et (S)-4-chloro-3-hydroxybutanoate ((S)-CHBE) catalyzed by AdhS. The addition of Me tert-Bu ether (MTBE) as an organic phase not only increased the uploading of COBE but also prevented the spontaneous hydrolysis of COBE, extended the lifetime of DH/Cc-PAA bioelectrode, and increased the Faradaic efficiency and the concentration of generated (R)-ethyl-4-cyano-3-hydroxybutyrate ((R)-CHCN). After 10 h of reaction, the highest concentration of (R)-CHCN in the biphasic bioelectrocatalytic system was 25.5 mM with 81.2% enantiomeric excess (ee_p). The conversion ratio of COBE achieved 85%, which was 8.8 times higher than that achieved with the single-phase system. Besides COBE, two other substrates with aromatic ring structures were also used in this biphasic bioelectrocatalytic system to prepare the corresponding chiral β-hydroxy nitriles. The results indicate that the biphasic bioelectrocatalytic system has the potential to produce a variety of β-hydroxy nitriles with different structures. 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. 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.

Evaluating solid phase (micro-) extraction tools to analyze freely ionizable and permanently charged cationic surfactants was written by Timmer, Niels;Scherpenisse, Peter;Hermens, Joop L.

Working with and anal. of cationic surfactants can be problematic since aqueous concentrations are difficult to control, both when taking environmental aqueous samples as well as performing laboratory work with spiked concentrations For a selection of 32 amine based cationic surfactants (including C8- to C18-alkylamines, C14-dialkyldimethylammonium, C8-tetraalkylammonium, benzalkonium and pyridinium compounds), the extraction from aqueous samples was studied. Aqueous concentrations were determined using solid phase extraction (SPE; 3 mL/60 mg Oasis WCX-SPE cartridges) with recoveries of ≥80% for 30 compounds, and ≥90% for 16 compounds Sorption to glassware was evaluated in 120 mL flasks, 40 mL vials and 1.5 mL autosampler vials, using 15mM NaCl, where the glass binding of simple primary amines and quaternary ammonium compounds increased with alkyl chain length. Sorption to the outside of pipet tips (≤20% of total amount in solution) when sampling aqueous solutions may interfere with accurate measurements. Polyacrylate solid phase microextraction (PA-SPME) fibers with 2 coating thicknesses (7 and 35 μm) were tested as potential extraction devices. The uptake kinetics, pH-dependence and influence of ionic strength on sorption to PA fibers were studied. Changing medium from 100mM Na⁺ to 10mM Ca²⁺ decreases K_fw with one order of magnitude. Results indicate that for PA-SPME neutral amines are absorbed rather than adsorbed, although the exact sorption mechanism remains to be elucidated. Further research remains necessary to establish a definitive applicability domain for PA-SPME. However, results indicate that alkyl chain lengths ≥14 C atoms and multiple alkyl chains become problematic. A calibration curve should always be measured together with the samples. In conclusion, it seems that for amine based surfactants PA-SPME does not provide the reliability and reproducibility necessary for precise sorption experiments, specifically for alkyl chain lengths beyond 12 C atoms. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Category: chlorides-buliding-blocks).

Design and evaluation of polarity controlled and recyclable deep eutectic solvent based biphasic system for the polarity driven extraction and separation of compounds was written by Tang, Weiyang;Row, Kyung Ho. And the article was included in Journal of Cleaner Production in 2020.Computed Properties of C25H54ClN The following contents are mentioned in the article:

Deep eutectic solvent (DES) based extraction methods have promising applications in extracting and separating compounds from plants. In this study, a polarity controlled biphasic extraction system consisting of a hydrophilic DES phase (Hexafluoroisopropanol-choline chloride: HFIP-ChCl) and a hydrophobic DES phase (Menthol-tricaprylylmethylammonium chloride: Menthol-N8881Cl) was constructed. The DES based biphasic system was successful in the simultaneous extraction and separation of high polarity compounds, such as chlorogenic acid (CHA), quercetin (QUE) and anthocyanidins (ANT), and a low polarity compound artemisinin(ART), from Artemisia annua Leaves in a single step by the polarity driven recognition targets. By adjusting the mole ratio of the component in each DES phase, the HFIP-ChCl(1:1)/Menthol-N8881Cl(2:1) biphasic system showed the best extraction and separation performance. A conductor-like screening model for real solvents (COSMO-RS) was used to monitor and analyze the changes in the surface polarity dynamics of each DES. The results showed that the non-polar intensity increased from 11.89 to 21.06 Å2 with increasing proportion of HFIP in HFIP-ChCl and the non-polar intensity weakened from 16.47 to 10.01 Å2 with increasing proportion of Menthol in Menthol-N8881Cl. This model can be efficient for screening suitable DESs in a DES based biphasic extraction system to accommodate compounds with a range of polarities. Supported by the model and exptl. data of the DES based biphasic system, 6.21 mg/g ART was transferred to the upper layer (Menthol-N8881Cl with 2:1 mol ratio) and 7.89 mg/g CHA, 5.5 mg/g QUE, and 8.9 mg/g ANT were transferred to the lower layer (HFIP-ChCl with 1:1 mol ratio) under the optimal condition (15/1 solvent/solid ratio, 40°C extraction temperature, 1:1 vol ratio and 30 min extraction time). Therefore, the polarity controlled DES based biphasic extraction system was used to expand the application of DESs in the extraction and separation of bioactive compounds with various polarities.

Conceiving a simple, green, and mild one-pot route to grow and construct anisotropic bimetallic 3D architectures with multilevel structures and promising functions is highly desirable and tech. important in many applications. Herein, a facile ionic liquid-modulated strategy is presented for the preparation of hyperbranched Au₃Pd₁ bimetallic nanodendrites (NDs) in aqueous solution at room temperature To implement this protocol, HAuCl₄ and Na₂PdCl₄ are used as precursors and ascorbic acid as a reductant, and a common ionic liquid 1-butyl-3-methylimidazolium chloride ([C₄mim]Cl) is utilized to direct the anisotropic growth of 3D Au₃Pd₁ NDs, which exhibits an eco-friendly feature. It is shown that the alloy Au₃Pd₁ NDs possess multilevel architectures, i.e., primary 3D large flowers (with diameters of about 2.5-4.0μm), secondary 2D leaves, tertiary sym. branches, and quaternary sym. petals. A series of factors influencing morphologies and properties of the products are investigated, and the results indicate that both [C₄mim]Cl and Au/Pd at. ratios are crucial to the formation of 3D Au₃Pd₁ NDs. Owing to the well-defined morphol. and probable electronic effects between Au and Pd, the 3D Au₃Pd₁ NDs display high catalytic selectivity and good durability toward stepwise hydrogenation of 4-nitrophenylacetylene with a 100% conversion and 99.5% selectivity to 4-nitrostyrene in the first step and then 100% conversion from 4-nitrostyrene and 96.7% selectivity to 4-nitroethylbenzene in the second step. It is believed that the well-defined 3D Au₃Pd₁ NDs would also exhibit promising applications in other catalysis and eletrocatalysis applications.
