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).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.

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. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

Degradation of cationic surfactants using immobilized bacteria: Its effect on adsorption to activated sludge was written by Bergero, Maria F.;Lucchesi, Gloria I.. And the article was included in Journal of Biotechnology in 2018.COA of Formula: C25H46ClN The following contents are mentioned in the article:

Adsorption of cationic surfactants (QACs) Br-tetradecyltrimethylammonium (TTAB), Cl-tetradecylbenzyldimethylammonium (C₁₄BDMA) and Cl-hexadecylbenzyldimethylammonium (C₁₆BDMA) to activated sludge from a wastewater treatment plant was tested. Adsorption equilibrium was reached after 2h, and for initial 200mgL^-1 81%, 90% and 98% of TTAB, C₁₄BDMA and C₁₆BDMA were resp. adsorbed. After six successive desorption cycles, 21% of TTAB and 12.7% of C₁₄BDMA were desorbed from the sludge. In agreement with the percentage of QACs pre-adsorbed, the more hydrophobic the compound, the lesser the extent of desorption. Wastewater samples with activated sludge were supplemented with TTAB 200mgL^-1 and Ca-alginate beads containing the QACs-degrading microorganisms Pseudomonas putida A (ATCC 12633) and Aeromonas hydrophila MFB03. After 24h, 10mgL^-1 of TTAB were detected in the liquid phase and 6-8mgL^-1 adsorbed to the sludge. Since without Ca-alginate beads or with empty beads total TTAB amount (phase solid and liquid) did not change, the 90% reduction of the initial 200mgL^-1 after treatment with immobilized cells was attributed to the bacterial consortium’s capacity to biodegrade QACs. The results show the advantages of using immobilized bacteria to achieve complete QACs elimination from wastewater systems, thus preventing them from reaching the environment.

A number of techniques, including conductivity, surface tension, dynamic light scattering, transmission electron microscopy, and ¹H NMR (¹H NMR), Fourier transform IR (FT-IR), and ¹H-¹H 2D nuclear Overhauser effect spectroscopy (¹H-¹H 2D NOESY), have been used to investigate the effect of amide bonds on the interfacial and assembly properties of a cationic surfactant, N-anilinoformylmethyl-N-cetyl-N,N-dimethyl ammonium chloride (AMC-C₁₆), in aqueous solutions The adsorption of AMC-C₁₆ has been found to be much better than that of the conventional cationic surfactant, benzyl cetyldimethylammonium chloride (BAC-16) at the air/water interface and in solution The surface tension measurements show the presence of two critical aggregation concentrations (CAC₁ and CAC₂) for AMC-C₁₆. The presence of a strong intermol. hydrogen bond of AMC-C₁₆ was confirmed by ¹H NMR and FT-TR. The mol. interactions of AMC-C₁₆ were detected by ¹H-¹H 2D NOESY. The results show that the rigid group (phenyl) of AMC-C₁₆ was partially overlapped with its alkyl chain in aqueous solution, and the possible aggregation behavior for AMC-C₁₆ was proposed. The effects of an inorganic salt (NaCl) and an organic salt (C₆H₅COONa) to the aggregates of AMC-C₁₆ have been discussed.

Gold nanoparticles optical properties induced by water and an ionic liquid (bmimBF₄) inside cationic reverse micelles was written by Blach, Diana;Martinez O., Fernando. And the article was included in New Journal of Chemistry in 2017.Electric Literature of C25H46ClN The following contents are mentioned in the article:

The authors report the effect of a polar solvent entrapped in benzyl-n-hexadecyldimethylammonium chloride (BHDC) reverse micelles (RMs) as nanoreactors for the synthesis of gold nanoparticles (AuNPs). We evaluate how the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF₄) and water inside the RMs could control the interactions at the interface as a key factor that affects the final properties of the synthesized nanoparticles. The results show that the bmimBF₄ supramol. network under confinement plays an important role in the nucleation and growth mechanism of AuNPs. In addition, the results show how the polar solvent could induce a specific interaction at the interface, including ionic segregation, which affects the BHDC chloride (Cl^–) counterion availability at the interface, droplet size, interface flexibility and thus the material exchange rate between droplets. These factors strongly influence the AuNPs size, polydispersity, morphol. and crystallinity. The RTIL bmimBF₄ in BHDC RMs induces a decrease in ionic segregation of the Cl^– ions available at the interface which favors sphericity and monocrystallinity in the AuNPs formed. Moreover, water does not affect the availability of Cl^– ions at the interface, and the insertion of these ions in the previous crystalline layer is a key factor in the anisotropy and polycrystallinity of the AuNPs obtained. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

The impact and mechanism of quaternary ammonium compounds on the transmission of antibiotic resistance genes was written by Han, Yue;Zhou, Zhen-Chao;Zhu, Lin;Wei, Yuan-Yuan;Feng, Wan-Qiu;Xu, Lan;Liu, Yang;Lin, Ze-Jun;Shuai, Xin-Yi;Zhang, Zhi-Jian;Chen, Hong. And the article was included in Environmental Science and Pollution Research in 2019.SDS of cas: 122-18-9 The following contents are mentioned in the article:

The emergence of antibiotic resistance genes (ARGs) in microbes can be largely attributed to the abuse and misuse of antibiotics and biocides. Quaternary ammonium compounds (QACs) have been used worldwide as common disinfectants and detergents; however, their potential impact on the spread and diffusion of ARGs is still unknown. In this study, we detected the QAC resistance gene (qacEΔ1), the 1 integron gene (intI1), and 12 ARGs (sul1, sul2, cfr, cml, fexA, tetA, tetG, tetQ, tetX, ermB, bla_TEM, and dfrA1) in 48 water samples from three watersheds by quant. PCR (qPCR). We investigated the evolution of bacterial antibiotic resistance under QAC and antibiotic environmental pressures by long-term continuous culture. The changes in bacterial cell membrane and production of reactive oxygen species (ROS) were detected by flow cytometry, revealing the mechanism by which QAC affects the spread of antibiotic resistance. Our results showed that the QAC resistance gene was ubiquitous in watersheds and it had significant correlation with intI1 and seven ARGs (r = 0.999, p < 0.01). QACs could increase the resistance of bacteria to multiple antibiotics. QACs enhanced membrane permeability of bacterial cells and stimulated bacteria to produce ROS, which potentially promoted the transfer of plasmids between bacteria. In conclusion, this study demonstrated that QACs may facilitate the evolution and gene transfer of antibiotic resistance gene among microbiome.

Shape-Control of Pt-Ru Nanocrystals: Tuning Surface Structure for Enhanced Electrocatalytic Methanol Oxidation was written by Huang, Liang;Zhang, Xueping;Wang, Qingqing;Han, Yujie;Fang, Youxing;Dong, Shaojun.

Despite the fact that both electrochem. experiments and d. functional theory calculations have testified to the superior electrocatalytic activity and CO-poisoning tolerance of PtRu alloy nanoparticles toward the MeOH oxidation reaction (MOR), the facet-dependent electrocatalytic properties of PtRu nanoparticles are scarcely revealed because it is extremely difficult to synthesize well-defined facets-enclosed PtRu nanocrystals. We, for the 1st time, report a general synthesis of ultrathin PtRu nanocrystals with tunable morphologies (nanowires, nanorods, and nanocubes) through a 1-step solvothermal approach and a systematic study of the structure-directing effects of different surfactants and the formation mechanism by control experiments and time-dependent studies. We use these {100} and {111} facets-enclosed PtRu nanocrystals as model catalysts to evaluate the electrocatalytic characteristics of the MOR on different facets. Remarkably, {111}-terminated PtRu nanowires exhibit much higher stability and electrocatalytic mass activity toward MOR, which are 2.28 and 4.32 times higher than those of {100}-terminated PtRu nanocubes and com. Pt/C, resp., indicating that PtRu {111} facets possess superior MeOH oxidation activity and CO-poisoning resistance relative to {100} facets. This work provides a series of well-defined PtRu nanocrystals with tunable facets which would be ideal model electrocatalysts for fundamental research in fuel cell electrocatalysis.

And the article was included in Polymer Chemistry in 2017.Application of 122-18-9 The following contents are mentioned in the article:

A novel fluoropolymer having triazine rings and thermo-crosslinkable benzocyclobutene units is prepared by a facile phase transfer catalyzed interfacial polycondensation reaction between a diphenol and a dichloro-s-triazine. This is the first example of thermo-crosslinkable fluoropolymer containing triazine units. The polymer shows a high mol. weight (M_n) of more than 70 000, good solubility and film-forming ability, as well as high storage stability. When treated at a high temperature (>200 °C), the polymer easily converts to a crosslinked network, showing a low dielec. constant (D_k) of 2.58 at a range of frequencies from 0.1 to 30.0 MHz. Moreover, the crosslinked network exhibits a dielec. strength of 157.7 kV cm^-1, which is comparable with that of a widely used resin poly(2,6-dimethyl-1,4-phenylene ether). D-E loop tests indicate that the cured polymer possesses linear dielec. properties. The cured polymer also exhibits high hydrophobicity, which endows the polymer with a low water uptake of 0.11% after immersing it in water at room temperature for 72 h. Moreover, the crosslinked network exhibits high thermo-stability with a glass transition temperature of 264 °C and a 5 wt% loss temperature of 426 °C, as well as good mech. properties with an average hardness of 0.48 GPa and an average Young’s modulus of 11.92 GPa.

The aggregation and adsorption properties of metallosurfactant, benzyldimethylhexadecylammonium tetrachloromanganate(II) (BDHA₂[MnCl₄], where BDHA represents benzyldimethylhexadecylammonium group) in binary aqueous mixtures of ethylene glycol (EG) were investigated by tensiometric, conductometric, dynamic light scattering (DLS) and transmission electron microscopy (TEM) methods at 298.15 K. The percentage of EG (by weight) was varied between 0 and 100%. The physicochem. properties determined and discussed include critical micelle concentration (cmc), counterion binding constant (β), Gibbs free energy of micellization (), surface excess at cmc (), min. area per surfactant mol. (), surface pressure (πcmc), min. free energies (Gmin) and size of aggregates. This study revealed that with increase in percentage of EG the cmc of BDHA₂[MnCl₄] metallosurfactant increases and the cmc of BDHA₂[MnCl₄] in EG is about 158 times higher than that in water. The counterion binding constant values increase with increase in percentage of EG from 10% to 70% and thereafter decrease. The adsorption of metallosurfactant at the air-solution interface decreases as the EG content in the bulk increases. The values were found to be neg. and the neg. value decreases with increase in percentage of EG. Gordon parameter and ratio of surface tension of medium to that of the metallosurfactant solution at cmc are used to represent solvophobicity of the medium.

Reconfigurable hybrid nanoparticles made by decorating flexible polymer shells on rigid inorganic nanoparticle cores can provide a unique means to build stimuli-responsive functional materials. The polymer shell reconfiguration has been expected to depend on the local core shape details, but limited systematic investigations have been undertaken. Here, two literature methods are adapted to coat either thiol-terminated polystyrene (PS) or polystyrene-poly(acrylic acid) (PS-b-PAA) shells onto a series of anisotropic gold nanoparticles of shapes not studied previously, including octahedron, concave cube, and bipyramid. These core shapes are complex, rendering shell contours with nanoscale details (e.g., local surface curvature, shell thickness) that are imaged and analyzed quant. using the authors’ customized anal. codes. It is found that the hybrid nanoparticles based on the chosen core shapes, when coated with the above two polymer shells, exhibit distinct shell segregations upon a variation in solvent polarity or temperature It is demonstrated for the PS-b-PAA-coated hybrid nanoparticles, the shell segregation is maintained even after a further decoration of the shell periphery with gold seeds; these seeds can potentially facilitate subsequent deposition of other nanostructures to enrich structural and functional diversity. These synthesis, imaging, and anal. methods for the hybrid nanoparticles of anisotropically shaped cores can potentially aid in their predictive design for materials reconfigurable from the bottom up.
