It is very challenging to completely break the corona symmetry of polymer vesicles as usually their inner and outer coronas have the same constituents. Herein, we propose a novel micelle-to-vesicle strategy to achieve this goal. First, a poly(ethylene oxide)₁₁₃-b-poly[N-iso-Pr acrylamide₄₅-stat-7-(2-methacryloyloxyethoxy)-4-methylcoumarin₁₀]-b-poly(2-(diethylamino)ethyl methacrylate)₂₈ [PEO₁₁₃-b-P(NIPAM₄₅-stat-CMA₁₀)-b-PDEA₂₈] triblock copolymer was synthesized and self-assembled into micelles, which were then transformed into asym. vesicles. The PEO block formed the outer corona of the vesicles, the PDEA block formed the inner corona of the vesicles (initially acted as the core-forming block of micelles), and the P(NIPAM-stat-CMA) block formed the membrane of vesicles (initially acted as the middle corona or the shell of micelles). Symmetry breaking was achieved during the micelle-to-vesicle transition where the locations of the inner and the outer coronas of vesicles were predetermined This asym. structure was confirmed by selective decoration with gold nanoparticles on the PDEA inner coronas. Furthermore, the inner coronas could efficiently prevent unwanted doxorubicin (DOX) leakage at physiol. conditions by turning themselves into an inner wall. Overall, we have hereby demonstrated a novel approach to prepare well-defined asym. vesicles through a finely controlled micelle-to-vesicle transition. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3HPLC of Formula: 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) 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. This gives them a high tenancy to accumulate in the food chain (biomagnification).HPLC of Formula: 5137-55-3

Use of Ionic Liquid Pretreated and Fermented Sugarcane Bagasse as an Adsorbent for Congo Red Removal was written by Ejaz, Uroosa;Wasim, Agha Arslan;Khan, Muhammad Nasiruddin;Alzahrani, Othman M.;Mahmoud, Samy F.;El-Bahy, Zeinhom M.;Sohail, Muhammad. And the article was included in Polymers (Basel, Switzerland) in 2021.Formula: C25H54ClN The following contents are mentioned in the article:

A large amount of industrial wastewater containing pollutants including toxic dyes needs to be processed prior to its discharge into the environment. Biol. materials such as sugarcane bagasse (SB) have been reported for their role as adsorbents to remove the dyes from water. In this study, the residue SB after fermentation was utilized for the dye removal. A combined pretreatment of NaOH and methyltrioctylammonium chloride was given to SB for lignin removal, and the pretreated SB was utilized for cellulase production from Bacillus aestuarii UE25. The strain produced 118 IU mL^-1 of endoglucanse and 70 IU mL^-1 of β-glucosidase. SEM and FTIR spectra showed lignin and cellulose removal in fermented SB. This residue was utilized for the adsorption of an azo dye, congo red (CR). The thermodn., isotherm and kinetics studies for the adsorption of CR revealed distinct adsorption features of SB. Untreated SB followed Langmuir isotherm, whereas pretreated SB and fermented SB obeyed the Freundlich isotherm model. The pseudo-second-order model fitted well for the studied adsorbents. The results of thermodn. studies revealed spontaneous adsorption with neg. standard free energy values. Untreated SB showed a 90.36% removal tendency at 303.15 K temperature, whereas the adsorbents comprised of pretreated and fermented SB removed about 98.35% and 97.70%, resp. The study provided a strategy to utilize SB for cellulase production and its use as an adsorbent for toxic dyes removal. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Formula: C25H54ClN).

Flame atomic absorption spectrometric determination of total chromium and cadmium in bean samples after ultrasonic-assisted microextraction using ionic liquid Aliquat-336 was written by Elik, Adil;Karakoy, Tolga;Cilesiz, Yeter;Altunay, Nail. And the article was included in Journal of the Iranian Chemical Society in 2021.Synthetic Route of C25H54ClN The following contents are mentioned in the article:

Abstract: A new and rapid microextraction approach termed as ultrasonic-assisted ionic liquid-based microextraction (UA-ILME) was developed using ionic liquid Aliquat-336 as extraction solvent for the extraction of chromium and cadmium in bean samples collected from different regions in Turkey. The total amounts of analytes in the samples were measured by flame at. absorption spectrophotometry. The basis of the extraction step is based on the complexation of Cr(III) and Cd(II) with diethyldithiocarbamate at pH 4.0. The hydrophobic ternary complexes containing analytes were then rapidly extracted from the sample solution to the ionic phase under the ultrasonic effect using tricaprylylmethylammonium chloride (Aliquat-336). Some exptl. variables (pH, ligand amount, extraction solvent volume, ultrasound time, extraction temperature and sample volume) were optimized in detail. Following the optimization steps, the limits of detection (LODs, 3Sblank/m) for Cr(III) and Cd(II) were calculated as 0.45 ng mL-1 with linear range of 1.5-380 ng mL-1 and 0.25 ng mL-1 with linear range of 0.8-220 ng mL-1, resp. Enrichment factors and average recoveries were ranged from 125.8-96.4 to 92.7-106.5%, resp. The accuracy and precision of the method were validated by analyzing a certified reference material and spiked recovery tests. The UA-ILME method was successfully applied to the determination of Cd and Cr in the samples, highlighting that the matrix ions under consideration do not affect the extraction and determination steps. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Synthetic Route of C25H54ClN).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides readily react with amines to give substituted amines.

New Insights on the Effects of Water on Polymer Inclusion Membranes Containing Aliquat 336 Derivatives as Carriers was written by Fontas, Claudia;Vera, Ruben;Antico, Enriqueta;Martinez de Yuso, Maria del Valle;Rodriguez-Castellon, Enrique;Benavente, Juana. And the article was included in Membranes (Basel, Switzerland) in 2022.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

Surface characterization of polymer inclusion membranes (PIMs) using the polymers cellulose triacetate and polyvinyl chloride, containing different ionic liquids (ILs) as carriers, has been performed. Three different ILs have been tested: com. trioctyl methylammonium chloride (Aliquat 336^–AlqCl^–) and two derivatives bearing the counter anion NO3- or SCN- (AlqNO₃ and AlqSCN, resp.). Surface anal. was performed by SEM (SEM) and XPS for both dry membranes and PIMs immersed for 4 days in ultrapure water to investigate the effect of the interaction of water with the membrane’s morphol. and composition XPS anal. of the PIMs revealed that immersion in ultrapure water causes a decrease in the at. concentration percentage (A.C.%) of the specific IL atoms (Cl, S, and N) when compared with dry samples. Moreover, SEM images of the PIMs containing the IL AlqNO₃ showed an alteration in the morphol. of the membrane due to water contact at surface level, whereas no changes were observed at a bulk level. These changes in the surface composition of the water equilibrated PIMs may be associated with the solubilization of the IL in the water solution, which, therefore, may affect the reactivity of the membrane’s surface. To better understand this effect, PIMs containing both AlqCl and AlqNO₃ as carriers were used for arsenic (V) transport. It was found that AlqCl was the most effective IL and that the effectivity of the PIM on As(V) removal was not affected after five cycles of the membrane’s reuse.

Tuning the ¹H NMR paramagnetic relaxation enhancement and local order of [Aliquat]⁺-based systems mixed with DMSO was written by Cordeiro, Rui;Beira, Maria J.;Cruz, Carlos;Figueirinhas, Joao L.;Corvo, Marta C.;Almeida, Pedro L.;Rosatella, Andreia A.;Afonso, Carlos A. M.;Daniel, Carla I.;Sebastiao, Pedro J..

Understanding the behavior of a chem. compound at a mol. level is fundamental, not only to explain its macroscopic properties, but also to enable the control and optimization of these properties. The present work aims to characterize a set of systems based on the ionic liquids [Aliquat][Cl] and [Aliquat][FeCl₄] and on mixtures of these with different concentrations of DMSO by means of ¹H NMR relaxometry, diffusometry and X-ray diffractometry. Without DMSO, the compounds reveal locally ordered domains, which are large enough to induce order fluctuation as a significant relaxation pathway, and present paramagnetic relaxation enhancement for the [Aliquat][Cl] and [Aliquat][FeCl₄] mixture The addition of DMSO provides a way of tuning both the local order of these systems and the relaxation enhancement produced by the tetrachloroferrate anion. Very small DMSO volume concentrations (at least up to 1%) lead to enhanced paramagnetic relaxation without compromising the locally ordered domains. Larger DMSO concentrations gradually destroy these domains and reduce the effect of paramagnetic relaxation, while solvating the ions present in the mixtures The paramagnetic relaxation was explained as a correlated combination of inner and outer-sphere mechanisms, in line with the size and structure differences between cation and anion. This study presents a robust method of characterizing paramagnetic ionic systems and obtaining a consistent anal. for a large set of samples having different co-solvent concentrations This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3COA of Formula: C25H54ClN).

To investigate the tensile and flexural strength of poured, subtractive, and additive manufactured denture base methacrylates bonded to soft and hard relining materials after hydrothermal cycling and microwave irradiation This study included a conventional (CB), subtractive (SB), and additive (AB) base material as well as a soft (SCR) and hard (HCR) chairside and one hard laboratory-side (HLR) relining material. Reference bodies of the base materials and bonded specimens to the relining materials were produced with a rectangular cross-section. The specimens were either pre-treated by water storage (50 h, 37 °C), hydrothermal cycling (5000 cycles, 5 °C and 55 °C, 30 s each), or microwave irradiation (6 cycles, 640 W, 3 min, wet). A tensile and four-point bending test were performed for a total of 504 specimens. Data were analyzed using multivariate anal. of variance (MANOVA) with post-hoc Tukey tests (α = 0.05). In comparison with the other reference groups SB showed marginally higher tensile and flexural strength (p < 0.047). Bond strength to SCR was affected neither by the base material nor by the pre-treatment (p > 0.085). HCR demonstrated twice the bond strength to AB compared with SB and CB (p ≤ 0.001). HLR showed the highest bond strength to CB (p ≤ 0.001). There was no difference between the specimens after hydrothermally cycling and microwave irradiation (p > 0.318). The bond strength of hard relining materials to subtractive and additive manufactured denture bases differ compared with conventional pouring.

Kinetic study on extraction of metal-cyanide complex ions by the N263-TBP system was written by Song, Yonghui;Li, Yifan;Zhang, Hongju;Zhou, Min;Liu, Gang. And the article was included in Journal of Molecular Liquids in 2022.Formula: C25H54ClN The following contents are mentioned in the article:

In this study, the extraction of metal-cyanide complex ions in gold-leaching, cyanide-containing wastewater by a trioctylmethylammonium chloride (N263)-tri-Bu phosphate (TBP)-n-octanol-sulfonated kerosene system was investigated. The effects of N263 and TBP concentrations, the aqueous phase pH, and phase ratio (O/A) on the extraction were investigated by adopting the response surface methodol., and the operating parameters were optimized. The optimal solution was obtained by solving the model optimally. A Cu ion concentration of 3,000 mg/L, an N263 concentration of 0.459 mol/L, a TBP concentration of 0.214 mol/L, an initial pH of the aqueous phase of 10.064, and O/A of 0.900 were determined to be optimal for realizing an extraction yield of 99%. The effects of column height, oil droplet volume, metal ion concentration, N263 and TBP concentrations, and temperature on the mass transfer rate were investigated using the single droplet method. Kinetic studies showed that the kinetic equation for the extraction system was Rf (Mass transfer rate) = 1.57 x 10^-4·CCu·CTBP·CN263. The apparent activation energy of Cu(I) was 15.186 kJ/mol. The extraction process was controlled by the diffusion process. Furthermore, the chem. reaction occurred at the two-phase interface, where the copper cyanide complex ions preferentially bound to TBP at the interface between the two phases, and the bound anion cluster then reacted with the N263 cation to form the extractive complex, which then entered the organic phase from the interface.

Molecular Simulation and Experimental Study on Low-Viscosity Ionic Liquids for High-Efficient Capturing of CO₂ was written by Zhao, Zhijun;Gao, Jubao;Luo, Mingsheng;Liu, Xinyue;Zhao, Yongsheng;Fei, Weiyang. And the article was included in Energy & Fuels in 2022.COA of Formula: C25H54ClN The following contents are mentioned in the article:

In recent decades, ionic liquids (ILs) have been developed as an ideal and reversible decarbonization solvent. However, some pitfalls, such as the low CO₂ capacity and high viscosity of ILs, limit their further scale up and industrial application. Therefore, in this work, three novel functional ILs [N₈₈₈₁][NIA], [N₈₈₈₁][For], and [N₈₈₈₁][Ac] were synthesized after using a mol. design method to capture CO₂ at 303.15-333.15 K and pressures up to 1000 kPa. The exptl. results illustrate that [N₈₈₈₁][NIA] presents the smallest viscosity and the highest CO₂ solubility The capacity order is [N₈₈₈₁][NIA] > [N₈₈₈₁][For] > [N₈₈₈₁][Ac] under the same exptl. conditions. The CO₂ recyclability experiments using [N₈₈₈₁][NIA] show the stability of CO₂ solubility after 5 cycles. The quantum chem. simulations at the level of DFT/B3LYP with 6-311++G(d,p) basis sets were used to study the CO₂ absorption mechanism in the studied ILs from the mol. viewpoint. Simulation results illustrated that the higher interaction energy between CO₂ and ILs means more CO₂ absorbed in these ILs, which agreed well with the exptl. results. The atoms in mols. theory and the function of the reduced d. gradient were also used to calculate the interactions in these IL-CO₂ systems. Results show that the majority of these interactions present an electrostatic character.

Systematic investigation on the abnormal surface and interfacial activity of fatty acid ionic liquids was written by Jia, Han;Wang, Shaoyan;Xu, Yingbiao;Wang, Tingyi;Zhang, Lingyu;Song, Jinyong;Zhang, Xuehao;Song, Lin;Jia, Haidong;Yan, Hui.

Ionic liquids are regarded as the promising and efficient additives to use in various aspects of petroleum industry, especially in chem. EOR. In this investigation, three novel fatty acid ionic liquids (FAILs), methyltrioctylammonium octanoate ([N8881][C8:0]), methyltrioctylammonium laurate ([N8881][C12:0]) and methyltrioctylammonium palmitate ([N8881][C16:0]), were selected and evaluated for their performances in terms of surface/interfacial activity, temperature and salt resistances. The three FAILs could cause remarkable reduction of surface tension to ∼30mN/m in their aqueous solutions, and the [N8881][C8:0] with the shortest anionic alkane chain exhibited the greatest surface activity among three FAILs. Then the size-match effect and intermol. interaction were employed to explain the abnormal variations, which were confirmed by the control experiments using mixed surfactants and the mol. dynamics simulation. It was found that the binding energy in [N8881][C8:0] (-28.961 kcal/mol) was larger than that in [N8881][C16:0] (-22.942 kcal/mol), which should be responsible for their different surface activity. Moreover, the crude oil/water interfacial tension (IFT) could be decreased to the much level (4.9 x10^-3 mN/m and 1.7 x 10^-2 mN/m) even at high-temperature conditions (80 °C) and at high-salinity conditions (100,000 mg/L), indicating the FAILs might be the ideal candidate for the EOR used surfactants with great temperature and salt tolerances. Meanwhile, the variations of IFT results further verified our proposed mechanism.
