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. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3SDS of cas: 5137-55-3).

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. 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).SDS of cas: 5137-55-3

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.

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.

Inhibition of asphaltene precipitation using hydrophobic deep eutectic solvents and ionic liquid was written by Sanati, A.;Malayeri, M. R.;Busse, O.;Weigand, J. J.. And the article was included in Journal of Molecular Liquids in 2021.Application of 5137-55-3 The following contents are mentioned in the article:

Precipitation and subsequent deposition of asphaltene in oil reservoirs may cause severe flow assurance problems due to clogging/blocking of pore spaces and wettability alteration of reservoir rocks towards oil-wetness. The present study focuses, for the first time, on the potential application of three hydrophobic deep eutectic solvents (HDESs) prepared by mixing methyltrioctylammonium chloride (N81Cl) as their hydrogen bond acceptor (HBA) with alc. hydrogen bond donors (HBDs), namely 1-propanol, 1,3-propanediol, and glycerol. The performance of HDESs was compared with a phosphonium-based hydrophobic ionic liquid (IL), Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate (TTPBP), as well as dodecylbenzene sulfonic acid (DBSA), a conventional asphaltene precipitation inhibitor. Initially, the kinetic and onset of asphaltene precipitation were evaluated using an UV-visible (UV-Vis) spectrophotometer to determine the chems.’ inhibition propensity. Next, Fourier-transform IR (FTIR) spectroscopy, thermogravimetric (TGA), and elemental analyses were used for the recovered asphaltenes from HDESs and TTPBP solutions to examine their structures. Spectrophotometry results revealed that glycerol-based HDES (HDES 3) and TTPBP could effectively inhibit the asphaltene precipitation, where their performances were comparable to that of DBSA. Besides, aromaticity index, thermal degradation, and H:C and oxygen contents provided evidence that HDES 3 and TTPBP could disrupt the asphaltenes structure, thus stabilizing them in the oleic environment.

Enhanced removal of sulfamethoxazole antibiotics from aquatic samples by electromembrane extraction process was written by Olasupo, Ayo;Ahmed, Naser;Kamil, Wan Maryam Wan Ahmad;Suah, Faiz Bukhari Mohd. And the article was included in Reactive & Functional Polymers in 2022.Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

The antibiotic sulfamethoxazole (SMZ) is an emerging organic contaminant of concern. Residual amounts of this contaminant have been reported at different concentrations in aquatic environments due to the inability of wastewater treatment plants to remediate this compound completely. In this study, a classical polymer inclusion membrane (PIM) comprised of the base polymer cellulose triacetate (CTA), the carrier Aliquat 336, and the plasticiser dioctyl phthalate (DOP) was used for SMZ remediation. After an extraction time of 40 h at pH 9, the PIM completely removed SMZ with a transport efficiency of 82%. In order to improve the transport of SMZ across the membrane, we investigated the impact of an elec. voltage through electromembrane extraction (EME) at 20-120 V. At an extraction time of 15 h and a voltage of 50 V, SMZ was removed completely with a transport efficiency of 100%. However, excessive bubbling at the electrode under higher voltages (≥70 V) led to membrane instability. Subsequently, the stability of the membrane was investigated by subjecting the same membrane to 12 cyclic mass transfers under the same conditions; there was a slight difference in the efficiencies of the membrane. A gradual loss of membrane mass was recorded after each exptl. cycle, attributed to the loss of the membrane liquid phase. Finally, the fabricated PIM was successfully used to preconc. SMZ from real environmental samples, with preconcentration factors ranging from 22.9-24.1. Hence, applying a voltage was essential to achieving the total recovery of SMZ.

Praseodymium (Pr) and neodymium (Nd) are considered as the light rare earth elements that have received significant attention due to their many applications. The extraction of Pr and Nd from NdFeB magnet-leaching solution using nitrate form of Aliquat 336 was investigated to show the interactive effects in solvent extraction process. The response surface methodol. (RSM) based on central composite design (CCD) was used for exptl. modeling and optimization. The studied variables included Aliquat 336 concentration of 0.30 to 0.85 mol/L, organic to aqueous phase ratio (O/A) of 1 to 3, pH of 2.0 to 5.0, and nitrate concentration of 2.2 to 5.6 mol/L. According to the results, it was found that there were effective inter-parameter interactions in which justified different feedbacks of the system under different operational conditions. Furthermore, two separated optimizations (i.e., co-extraction efficiency and operational selectivity) were also performed by desirability function method. In the optimization of co-extraction efficiency, the Pr and Nd extraction efficiencies were obtained 99.7% and 93.9%, resp., while, the above responses in the optimization of operational selectivity were obtained 74.8% and 61.2%, resp. The values of separation factor were determined same (i.e., 2.1) for both the optimizations. Meanwhile, it was found the stripping of Pr and Nd ions from the loaded organic phase can be effectively conducted under the 0.02 mol/L hydrochloric acid solution within a contact time of 5 min conditions.
