The work aims to establish high performance liquid chromatog. (HPLC) to determine the contents of three benzalkonium chlorides (dodecyl di-Me benzyl ammonium chloride, tetradecyl di-Me benzyl ammonium chloride, hexadecyl di-Me benzyl ammonium chloride) in packaging materials. Samples were extracted by methanol-water (volume ratio 1:1) ultrasound and centrifugal filtration, determined by diode array detector, and quantified by external standard method. The results showed that three benzalkonium chlorides had good linearity in the range of 10.0∼500.0 mg/L, and r² were less than or equal to 0.9996; the detection limit was 2.5∼5.0 mg/L; the limit of quantification was 10.0 ∼20.0 mg/L; the average recovery rate was 88.7%∼96.6%, and the relative standard deviation was 2.5%∼5.3%. The pretreatment of the proposed method is simple, and it is of high sensitivity and accuracy. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Application of 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. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water.

The phase behavior of alkyl ether carboxylate surfactants with cationic surfactant was studied. The effects of anionic surfactant structure, molar ratio, salinity and group number of polyether on the phase behavior of the anionic-cationic complex system were investigated by the phase behavior experiment The optimum salinities were found out for the different mixtures as 30 g/L, 100 g/L and 200 g/L. The critical micelle concentration (CMC) and surface tension of anionic surfactants, cationic surfactants and the mixture of anionic-cationic surfactants were tested. The results showed that these mixtures produced ultralow CMC (2 mg/L), low surface tension (32 mN/m), and high oil solubilization parameter (SP=12). The experiment results were possibly useful in developing new mixture of anionic/cationic surfactant used for enhanced oil recovery (EOR) application in different reservoir in the future.

Identification and subcellular localization analysis of two rubber elongation factor isoforms on Hevea brasiliensis rubber particles was written by Dai, Longjun;Nie, Zhiyi;Kang, Guijuan;Li, Yu;Zeng, Rizhong. And the article was included in Plant Physiology and Biochemistry in 2017.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Rubber elongation factor (REF) is the most abundant protein found on the rubber particles or latex from Hevea brasiliensis (the Para rubber tree) and is considered to play important roles in natural rubber (cis-polyisoprene) biosynthesis. 16 BAC (benzyldimethyl-n-hexadecylammonium chloride)/SDS-PAGE separations and mass spectrometric identification had revealed that two REF isoforms shared similar amino acid sequences and common C-terminal sequences. In this study, the gene sequences encoding these two REF isoforms (one is 23.6 kDa in size with 222 amino acid residues and the other is 27.3 kDa in size with 258 amino acid residues) were obtained. Their proteins were relatively enriched by sequential extraction of the rubber particle proteins and separated by 16 BAC/SDS-PAGE. The localization of these isoforms on the surfaces of rubber particles was further verified by western blotting and immunogold electron microscopy, which demonstrated that these two REF isoforms are mainly located on the surfaces of larger rubber particles and that they bind more tightly to rubber particles than the most abundant REF and SRPP (small rubber particle protein). This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).

Synthesis and stability of bimetallic Au@Ag nanorods was written by Wei, Jingjing;Kan, Caixia;Lou, Yeke;Ni, Yuan;Xu, Haiying;Wang, Changshun. And the article was included in Superlattices and Microstructures in 2016.Electric Literature of C25H46ClN The following contents are mentioned in the article:

Bimetallic Au@Ag nanorods (NRs) with high purity have been synthesized via Ag overgrowth on the surface of as-obtained Au nanobipypramid (Au NBP). With the presence of different surfactants (CTAC, CTAB and BDAC), the growth mechanism of Au@AgNRs was proposed. It is found that the formation of Au@AgNRs is highly dependent on halogen ion (Cl- or Br-) of the surfactants. The Ag overgrowth rate in BDAC is less than that in CTAC, and the aspect ratios of Au@AgNRs prepared by BDAC are larger than that by CTAC. The optical properties show that the SPR of Au@AgNRs can be tuned in a large Vis-NIR spectral region. FDTD simulation was used to investigate the plasmon properties and localized field distribution of Ag@AuNR monomer, indicating that Ag@AuNRs possess a high SPR quality factor. Compared with AuNRs, the stability of Au@AgNRs was investigated under laser (λ = 980 nm) irradiation with different power. It is found that Au@AgNRs have high stability in shape and optical property, while AuNRs transform into particle and the SPR damp quickly. This research will provide an important reference for the fabrication of Au@AgNRs and further application. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

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

Seedless co-surfactant-based dimensional and optical tunability of gold nanorods with simultaneous pH regulation was written by Kaur, Parveer;Chudasama, Bhupendra. And the article was included in Journal of Materials Science in 2017.Electric Literature of C25H46ClN The following contents are mentioned in the article:

Intense electromagnetic fields generated by the gold nanorods (GNRs) owing to their strong plasmon resonance make them promising candidate for applications in cancer diagnostics, photothermal therapy, single-mol. detection, drug delivery, etc. Use of GNRs in these applications as plasmon resonance probes depends on the extent to which their plasmon resonance band can be tuned into NIR region. The authors propose a facile seedless approach to synthesize GNRs in a cetyltrimethyammonium bromide (CTAB)-benzyledimethylhexadecylammonium chloride (BDAC) co-surfactant system with simultaneous pH regulation that yields GNRs with tunable plasmon resonance in tissue transparent NIR region. The role of binary co-surfactants, pH of the growth solution, and influence of the volume of the reducing agent on GNRs growth has been studied. Under optimized conditions, the longitudinal plasmon resonance band of GNRs can be tuned from 780-1300 nm by regulating the pH of the growth solution from 2.5 to 1.3. The role of co-surfactants and pH in the regulation of dimensions and thus plasmonic properties of GNRs synthesized by single-step seedless approach has been evaluated. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

Quantitative determination of multiple surfactants in water using HPLC-MS/MS was written by Wang, Xiaomeng;Kasperski, Kim. And the article was included in Analytical Methods in 2018.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Process water from oil sand operations contains chems. such as scale or corrosion inhibitors added during bitumen processing as well as soluble organics from the bitumen. Under a zero discharge policy, all process water must be stored on-site in tailings ponds. Since the environmental fate of many of these chems. is unknown, their widespread use has raised increasing concerns due to their potential impact on downstream aquatic ecosystems when the water containing these chems. seeps into the environment during operations or when it is discharged into the environment after operations (although some sort of water treatment will almost certainly be needed before such release is allowed). To determine the fate of these chems., one should selectively detect them and quantify their amount in the environment. In this study, a new HPLC-MS/MS method was developed to measure some typical process chems. Using this method, inorganic salts were separated from the chems. without any sample pre-treatment, and the ionic and non-ionic surfactants were detected and quantified. This method will be useful in the determination of potential impacts of individual process chems. on the environment. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).

Nanostructured polyelectrolyte-surfactant complex pervaporation membranes for ethanol recovery: the relationship between the membrane structure and separation performance was written by Zheng, Pei-Yao;Zhang, Ping;Sun, Zhi-Wei;Zhu, Chen-Hui;An, Quan-Fu. And the article was included in Chinese Journal of Polymer Science in 2018.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Polyelectrolyte-surfactant complexes (PESCs) were fabricated through the interaction of poly(acrylic acid) and four different cationic surfactants or their mixtures PESC membranes were prepared by solution casting method and were applied in ethanol recovery from aqueous solution via pervaporation. Elemental anal. (EA), Fourier transform IR spectroscopy (FTIR), water contact angle (CA) measurement, differential scanning calorimetry (DSC) and X-ray scattering were employed to characterize the composition, structure and properties of PESCs. The results reveal that the investigated PESCs are similar in hydrophobicity but different in hierarchical nanostructures. In separating 5 wt% ethanol/water mixture, PESC membranes with high crystallinity will have both low flux and ethanol selectivity because of the high packing d. and low permeability of crystalline regions. Meanwhile, the hierarchical nanostructures of PESC membranes change under pervaporation environment as was revealed by in situ synchrotron radiation X-ray scattering measurement. That is, the crystalline region could melt at high temperature in swelling state, thus consequently enhancing the ethanol selectivity. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).

And the article was included in Desalination and Water Treatment in 2018.Computed Properties of C25H46ClN The following contents are mentioned in the article:

Metronidazole (MNZ) is an antiparasitic that has been found in wastewater. In this paper, the removal of MNZ by using modified zeolitic tuffs with two different surfactants (hexadecyltrimethylammonium bromide and benzyl hexadecyl di-Me ammonium chloride) was studied. These modified materials were characterized by IR spectroscopy, X-ray diffraction, SEM/energy dispersive X-ray spectroscopy and Brunauer-Emmett-Teller anal. The cation exchange capacities and the points of zero charge were determined The sorption kinetics show that the equilibrium times for all systems were similar about 15 h, the exptl. data were best adjusted to the Ho-McKay model. The isotherms were linear indicating partition mechanism and the maximum adsorption capacity was in the order of 0.5 mg/g with an initial concentration of 20 mg/L of MNZ; the adsorption behavior of MNZ data at different temperatures was exothermic and the maximum adsorption capacity was observed between pH 5 and 6. The results show that the sorption efficiency depends on the origin of the zeolitic tuff and the surfactant used for the modification. These modified materials are effective to remove MNZ from aqueous solutions This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Computed Properties of C25H46ClN).

Recently, two-dimensional materials have gained increasing research attention due to their large surface area, high phys. and chem. stability, and excellent electrocatalytic performances. Herein, we reported a simple and fast one-pot aqueous method for synthesis of two-dimensional porous bimetallic PtPd alloyed nanosheets (NSs) using benzyldimethylhexadecylammonium chloride (HDBAC) as the capping agent and stabilizer. The formation mechanism involved the oriented attachment and self-assembly. The PtPd NSs exhibited excellent oxygen reduction reaction (ORR) activity with the pos. shift (c.a. 43 mV) of the half-wave potential in 0.1 M KOH solution, clearly outperforming that of com. Pt/C (50 wt%). Moreover, the as-prepared catalyst displayed 2.4 times enlargement in mass activity (MA, 382.10 mA mg^-1) and 3.5 times enhancement in specific activity (SA, 0.95 mA cm^-2) relative to those of Pt/C at 0.80 V. Meanwhile, the as-obtained catalyst demonstrated highly boosted hydrogen evolution reaction (HER) in 0.5 M H₂SO₄ electrolyte, surpassing that of Pt/C.

And the article was included in Electroanalysis in 2017.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

The present study described a novel application of simple potentiometric enzymic method for anal. of surfactants based on their inhibitory effect on acetylcholinesterase enzyme (AChE). The enzymic activity was measured through monitoring hydrolysis of acetylcholine (ACh) with a disposable acetylcholine potentiometric sensor. Comprehensive investigations were carried out including the effect of incubation time, cholinesterase enzyme and the working calibration ranges. Based on inhibition of AChE, different cationic, anionic and nonionic surfactants were determined in the concentration range from 0 to 40 μg mL^-1 with detection limits reaching 0.07 μg mL^-1 depending on the nature of surfactants. The degree of AChE inhibition caused by different tested surfactants were as follows: cetylpyridinium chloride (CPC)>benzyldimethylhexadecyl ammonium chloride (BDHAC)>Hyamine (Hy)>cetyltrimethylammonium bromide (CTAB)>Triton X-100 (TX-100)>sodium dodecyl sulfate (SDS). The proposed method was applied for determination of surfactants in pharmaceutical formulation, detergents products and environmental samples with acceptable sensitivity and reproducibility.
