Removal of organic micro-pollutants from water by β-cyclodextrin triazine polymers was written by Wang, Junzuo;Harrison, Mark. And the article was included in Journal of Inclusion Phenomena and Macrocyclic Chemistry in 2018.Formula: C25H46ClN The following contents are mentioned in the article:

β-Cyclodextrin (CD) polymers were synthesized by nucleophilic substitutions between β-CD with cyanuric chloride. Insoluble polymers were obtained. Polymers were characterized by DSC, TGA, FTIR, SS-¹³CNMR. Polymers and activated carbon (AC-Darco) were used to remove model micro-pollutants of bisphenol-A (BPA), 2-naphthol, 2-cholor-biphenyl (PCBNO1), benzene and di-Bu phthalate from water. The results showed that β-CD-triazine polymers showed better performance to adsorb BPA compared with activated carbon; β-CD-triazine polymer showed similar performance to activated carbon on removing benzene from water; however, it showed worse performance for removing 2-naphthol, PCBNO1 and dibutylphthalate by comparison with activated carbon. β-CD-triazine polymers with varying ratio of β-CD to cyanuric chloride were synthesized and their performance on model micro-pollutants were evaluated. Removal efficiency of micro-pollutants from water for β-CD-triazine polymers correlated with their CD concentration except for removing benzene which showed similar performance. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Formula: C25H46ClN).

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.

Gold nanostructures in general and gold nanorods in particular due to their plasmon resonance has been employed for many applications, such as biosensors. For the biosensors uses, gold nanorods remain popular and reproducibility of them is the most important and critical In the present work we used six different CTAB (Hexadecyltrimethylammonium bromide) products and one BDAC (Benzyldimethylhexadecylammonium chloride) with varying silver nitrate concentration in the seed-mediated growth of gold nanostructures. We synthesized gold nanorods with varying aspect ratio up to 5.5 with a longitudinal surface plasmon resonance peak from 670 to 950 nm. We obtained excellent rod-shape gold nanostructures witch were reliable and reproducible with our method based on common seed-mediated growth. The synthesized nanostructures were characterized by UV-visible spectroscopy, transmission electron microscopy (TEM) and X-ray diffraction (XRD). Here, we report our method in more detail as a user-friendly guide for the production of gold nanorods and tuning of their aspect ratios.

Three novel quaternary ammonium based poly(ionic liquid)s (PILs) were prepared and developed, expecting to increase the viscosity of liquid CO₂ (LCO₂). The Vinyl benzoate and various quaternary ammonium salts was used to provide CO₂-philicity group and viscosity-increasing groups resp. And the PILs products (TDBAS, HDBAS and SDBAS) were synthesized with three processes consisting of polymerization, sulfonation and ion exchange. The characterization results of gel permeation chromatog. (GPC), NMR spectrum (NMR), fourier transform IR spectrometer (FT-IR), element anal. (EA) and thermogravimetric anal. (TGA) confirmed the successful synthesis of the PILs. Based on the discussion of reverse micelle microstructures and interfacial tension of prepared PILs systems, the viscosity-increasing mechanisms of the prepared PILs were analyzed and explicated. The exptl. results indicated that the HDBAS presented an outstanding viscosity-increasing effect and acceptable water solubility among all the PILs, which may have a prosperous prospect in the near future.

Development of simple drift tube design for ion mobility spectrometry based on flexible printed circuit board material was written by Chantipmanee, Nattapong;Hauser, Peter C.. And the article was included in Analytica Chimica Acta in 2021.Synthetic Route of C25H46ClN The following contents are mentioned in the article:

A study on the use of flexible printed circuit board material for the construction of drift tubes for ion mobility spectrometry is reported. This is significantly less complicated than the conventional approach based on stacked electrode and insulator rings, as the material can simply be rolled up to obtain a string of circular electrodes. The size and spacing of the electrodes was found to have a strong effect on the resolving power. For an optimized geometry with electrodes of 1.5 mm width at a pitch of 3.5 mm resolving powers of up to 80 were achieved for quaternary amines introduced by electrospray ionization into a drift tube of 10 cm length and an applied voltage of 4200 V. This performance was found to be comparable to that of a conventional drift tube based on stacked rings with otherwise identical geometry and operating conditions. The entire instrument was constructed inhouse. Its utility was demonstrated with the determination of the C12, C14 and C16 benzalkonium ions in several com. cleaning products with limits of detection of 20, 25, and 38μg L^-1, resp.

Biodegradable Surface Active D-Glucose Based Quaternary Ammonium Ionic Liquids in the Solventless Synthesis of Chloroprene was written by Erfurt, Karol;Markiewicz, Marta;Siewniak, Agnieszka;Lisicki, Dawid;Zalewski, Mariusz;Stolte, Stefan;Chrobok, Anna. And the article was included in ACS Sustainable Chemistry & Engineering in 2020.Synthetic Route of C25H46ClN The following contents are mentioned in the article:

Five ionic liquids based on a quaternary ammonium core substituted with a D-glucose moiety and alkyl chains of varying length were synthesized as prospective phase-transfer catalysts. The catalytic activity of the obtained ionic liquids was tested in the dehydrochlorination of 3,4-dichloro-1-butene to chloroprene. The reaction proceeded in a two-phase system in the presence of an aqueous solution of sodium hydroxide. The results showed that the longer the alkyl chain in the cation, the higher the activity of the ionic liquid as a phase-transfer catalyst. The tested ionic liquids gave an easily recyclable system compared to classical phase-transfer catalysts that were soluble in the reaction system, with no leaching observed over five cycles (chloroprene yield >99%). The cytotoxicity and biodegradability of a series of synthesized ionic liquids based on D-glucose were determined so that a preliminary hazard assessment could be undertaken.

The Use of AOBH-DEHP Molecular Probe to Characterize BHDC Reverse Micelles Interfaces. Insights on the Interfacial Water Structure was written by Crosio, Matias A.;Silber, Juana J.;Moyano, Fernando;Correa, N. Mariano;Falcone, R. Dario. And the article was included in ChemistrySelect in 2017.Synthetic Route of C25H46ClN The following contents are mentioned in the article:

This work presents the use of the mol. probe: 3,6-bis(dimethylamino) acridinium bis-(2-ethylhexyl) phosphate salt, AOBH-DEHP. This probe is used to gain insights into the properties of the benzene/benzyl-n-hexadecyldimethylammonium chloride (BHDC)/water reverse micelles (RMs) interfaces. The techniques employed were absorption and emission spectroscopy in addition to the steady-state and, time-resolved fluorescence emission. For BHDC RMs without water addition, AOBH-DEHP can be used to determine the critical micellar concentration, CMC. Upon addition of water, we detect, at concentrations of BHDC lower < 1×10^-2 M, a proton transfer process from the AOBH⁺ cation to the DEHP^– anion producing AOB species. However, for [BHDC] > 10^-2 M, when the RMs is completely formed this process is reverted because water mols. at the interface interact with the cationic polar head of BHDC through the oxygen non-bonding electron pair enhancing their hydrogen bond ability and acidity, hence it can easily transfer a proton to AOB species to form AOBH⁺.

Successive Resonances for Ion Ejection at Arbitrary Frequencies in an Ion Trap was written by Snyder, Dalton T.;Cooks, R. Graham. And the article was included in Journal of the American Society for Mass Spectrometry in 2016.Application In Synthesis of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

The use of successive resonances for ion ejection is demonstrated here as a method of scanning quadrupole ion traps with improvement in both resolution and sensitivity compared with single frequency resonance ejection. The conventional single frequency resonance ejection waveform is replaced with a dual-frequency waveform. The two included frequencies are spaced very closely and their relative amplitudes are adjusted so that the first frequency that ions encounter excites them to higher amplitudes where space charge effects are less prominent, thereby giving faster and more efficient ejection when the ions come into resonance with the second frequency. The method is applicable at any arbitrary frequency, unlike double and triple resonance methods. However, like double and triple resonance ejection, ejection using successive resonances requires the radiofrequency and AC waveforms to be phase-locked to retain mass accuracy and mass precision. The improved performance is seen in mass spectra acquired by radiofrequency amplitude scans (resonance ejection) as well as by secular frequency scans.

Spontaneous catanionic vesicles formed by the interaction between an anionic β-cyclodextrins derivative and a cationic surfactant was written by Silva, O. Fernando;de Rossi, Rita H.;Correa, N. Mariano;Silber, Juana J.;Falcone, R. Dario. And the article was included in RSC Advances in 2018.Synthetic Route of C25H46ClN The following contents are mentioned in the article:

The present work shows the synthesis of a new type of catanionic surfactant, ModCD14-BHD, which involves an anionic amphiphilic cyclodextrin and the cationic benzyl-n-hexadecyldimethylammonium (BHD). It is obtained from the simple association of the cationic surfactant benzyl-n-hexadecyldimethylammonium chloride (BHDC) and β-cyclodextrin (β-CD) monosubstituted with an alkenyl succinate group (Mod-β-CD14). ModCD14-BHD form unilamellar vesicles spontaneously in water, while the individual components (BHDC and Mod-β-CD14) do not. The vesicles were character-ized by dynamic light scattering (DLS), transmission electron microscopy (TEM), SEM (SEM) and ¹H NMR techniques. We suggest that the formation of an inclusion complex between some of the cyclodextrins units and the long hydrocarbon moiety of the cationic surfactant play a crucial role in the vesicles formation. Besides, some or the cavities are available to interact with an external guest. We think that the new surfactant mol. has properties that may lead to important applications in biomedical and pharmaceutical sciences.

And the article was included in Analytical Methods in 2021.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

The discharge of wastewater containing surfactants and other industrial pollutants is contaminating the world’s water resources which should be taken seriously. This paper describes a paper spray mass spectrometric (PS-MS) method for rapid and quant. anal. of anionic and cationic surfactants in water samples. Eight cationic surfactants and four anionic surfactants can be simultaneously determined in pos. or neg. mode without sample pretreatment and chromatog. separation The PS-MS anal. time was only 10 s. Under optimized conditions, the method presented a suitable linear range (1-80μg mL-1, linear regression coefficients (R2) higher than 0.995 for cationic surfactants, R2 higher than 0.990 for anionic surfactants), a low limit of detection (0.05-0.35μg mL-1 for cationic surfactants and 0.20-0.35μg mL-1 for anionic surfactants), and satisfactory recovery values (97.3-106.1%). The method validation indicated that the method precision and accuracy were satisfactory. The results demonstrated that PS-MS is especially suitable for the high-throughput anal. of surfactants in water samples.

Extended delivery of non-steroidal anti-inflammatory drugs through contact lenses loaded with Vitamin E and cationic surfactants. was written by Torres-Luna, Cesar;Hu, Naiping;Tammareddy, Tejaswi;Domszy, Roman;Yang, Jeffrey;Wang, Nam Sun;Yang, Arthur. And the article was included in Contact lens & anterior eye in 2019.Computed Properties of C25H46ClN The following contents are mentioned in the article:

The purpose of this study is to extend drug release from ACUVUE Oasys® and ACUVUE TruEye® silicone hydrogel contact lenses by incorporation of vitamin E in conjunction with a cationic surfactant. In ACUVUE Oasys® and ACUVUE TruEye®, the release of ketorolac tromethamine and flurbiprofen sodium is extended from hours to several days for 11% and 21% vitamin E, (weight of vitamin E / weight of dry lens) but with a considerable reduction in the amount of drug released. Cetalkonium chloride and stearylamine increased the drug loading capacity which was otherwise compromised by the addition of vitamin E in the contact lenses. In the case of diclofenac sodium, a sustained release over 150 h for both contact lenses can be achieved. It was found that the release-time-increase factor due to vitamin E has a linear dependence with the octanol-water partition coefficient of the drug in ACUVUE Oasys®. The results in this study show that contact lenses loaded with vitamin E in conjunction with cationic surfactants achieved sustained release of non-steroidal anti-inflammatory drugs (NSAIDs) within the therapeutic window.
