And the article was included in Journal of Molecular Liquids in 2022.Electric Literature of C25H54ClN The following contents are mentioned in the article:

Owing to their unique characteristics, deep eutectic solvents (DESs) have the potential to replace organic solvents in the extraction and separation of chems. from natural sources. In this study, a novel biphasic system composed of hydrophilic and hydrophobic DESs was designed for the selective separation of geniposidic acid (GPA) and aucubin (AU) from Eucommia ulmoides male flowers. Fifteen DESs with different hydrophilicity/hydrophobicity were used to design the biphasic system. The biphasic system designed using tetra-Bu ammonium chloride-hexanoic acid and choline chloride-D, L-malic acid was found to be an optimal extraction system. The influence of the phase volume ratio, system concentration, water content in the DESs, equilibrium temperature, and pH of the phosphate buffer solution was investigated through single-factor experiments Under optimal conditions, maximum extraction efficiencies were observed for GPA in the top phase (EGPA = 94.59%) and AU in the bottom phase (EAU = 80.41%). Further, d. functional theory calculations indicated that H-bond interaction was the main factor influencing the selective separation of GPA and AU. This DES-based biphasic system is efficient and environmentally friendly and could be used in the separation of other homologues present in natural products. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Electric Literature of C25H54ClN).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) 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. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Electric Literature of C25H54ClN

New metal-free nanolubricants based on carbon-dots with outstanding antiwear performance was written by Chimeno-Trinchet, C.;Pacheco, M. E.;Fernandez-Gonzalez, A.;Diaz-Garcia, M. E.;Badia-Laino, R.. And the article was included in Journal of Industrial and Engineering Chemistry in 2020.COA of Formula: C25H54ClN The following contents are mentioned in the article:

Nanoparticles have already demonstrated a good performance in improving the wear and/or coefficient of friction when used as nanolubricants. Nevertheless, they show two main drawbacks: most of them are metal-based and, therefore, eco-unfriendly, and they are mostly hydrophilic and, consequently, unstable in organic media, which finally drives to aggregation/sedimentation and the loose of the good properties. In this work, we carry out the synthesis of carbon-based nanoparticles for additives in lubricants from two different approaches: either using ionic liquids as carbons source, or using glutathione as carbon source and decorating the so-obtained carbon dots with the big organic cations of the ionic liquid The final materials (diameters between 2.2 and 3.5 nm) were characterized by TEM, FTIR, XPS, and luminescent methodologies, finding long-term stability of the suspensions in organic media (≥15 days). Carbon dots obtained directly from the ionic liquids, in particular from methyltrioctylammonium chloride (MTOACDs) have demonstrated to be the best candidate as additive in different base oils (0.1%, w/v) and lubrication regimes, reducing the coefficient of friction about 30% and wear scar in more than 60% in the most extreme of the tested conditions (120 N). Addnl., nanolubricants are metal-free and therefore, more eco-friendly than classic additives. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3COA of Formula: C25H54ClN).

K. M.;Mohammad, Abdul Wahab. And the article was included in Materials Today: Proceedings in 2021.Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

Glutamic acid (GA) is an amino acid which is usually appear in the zwitterionic form in solutions At present, cation and anion exchange carriers are widely use to extract this amino acids. However, the carriers only function either at high pH or low pH. Although, the pH can be adjusted by adding certain chem. to reach acidic or basic region, but it may lead to addnl. byproducts formation and affect the extraction process. In the current study, supported liquid membrane (SLM) was used to extract the zwitterionic form of GA from the aqueous solution without any pH adjustment. In the SLM process, the determination of the best carrier in liquid membrane formulation is important for achieving high extraction of GA. Hence, different types of carriers such as trioctylamine (TOA), tridodecylamine (TDA), tri-n-octyl phosphine oxide (TOPO), mixture of 50% TOA and 50% TDA, aliquat 336 and di-2-ethylhexyl phosphoric acid (D2EHPA) in 2-ethyl-1-hexanol were investigated. The polyethersulfone (PES) membrane with and without graphene membrane supports were prepared, characterized and used as the support in the SLM. The incorporation of graphene in PES membrane had increased the surface contact angle and tensile stress from 80.96 ± 1.92° to 97.8 ± 1.46° and 650.684 kPa to 1079.59 kPa, resp. Aliquat 336 was identified as the best carrier with 93% of GA extraction This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Safety of N-Methyl-N,N-dioctyloctan-1-aminium chloride).

The present investigation deals with separation of various types of nitrophenols using SILM technique. Several ionic liquids were developed and the SILM parameters such as role of ILs, feed and strip phase concentration, wastewater pH, salt effect and mixture of pollutants were thoroughly investigated. The percentage extraction and stripping, flux, apparent rate constants and selectivity were evaluated. The selected ammonium IL being more polar than the imidazolium IL showed better separation of 2-nitrophenol. The SILM constituting an ammonium IL with SCN anion exhibited extraction efficiency of >96% and Ka: 0.264 h^-1. The change in feed concentration showed maximum transport of nitrophenol at 300 ppm concentration (Ka: 0.673 h^-1). The membranes were repeated for 4 cycles which demonstrated good stability for runs of more than 48 h. The selectivity of 2-nitrophenol, 2,4-dinitrophenol, 2,4,6- trinitrophenol over nitrobenzene was 26, 36 and 58, resp. The morphol. of membranes was studied by using FTIR and FE-SEM and the transport mechanism was elucidated. With the optimized parameters, a concentration factor of 7 can be achieved in the present SILM system. The application of SILM including ammonium IL with SCN anion shows a promising potential for the treatment of various types of nitrophenol bearing wastewater.

And the article was included in Journal of Luminescence in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

As an emerging light-harvesting and light-emitting materials, all-inorganic perovskite nanocrystals (AIPNCs) have attracted widespread attentions in optoelectronic materials and devices. However, great challenges exist for the fabrication of novel AIPNCs demonstrating magnetic properties. Here, magnetic AIPNCs (M-AIPNC) with well-defined hybrid nanostructures of Fe₃O₄@SiO₂@AIPNC are proposed. The core-shell structured chem. encapsulation and the in-situ crystal growth are designed to fabricate the magnetic substrate of Fe₃O₄@SiO₂ and to link the AIPNCs, resp. The as-prepared M-AIPNCs display brilliant blue, green and red photoluminescence by adjusting the chem. compositions of AIPNCs. The M-AIPNCs also demonstrate enhanced water stability due to their surficial hydrophobicity. The photoluminescence of Fe₃O₄@SiO₂@AIPNC in the heating process exhibits a power exponential temperature response, and can be recovered in the cooling process. Most importantly, the M-AIPNCs can realize the mobile photoluminescence driven by a remote magnetic field. The M-AIPNCs with multi-colored fluorescence, excellent fluorescence stability, reversible temperature response and non-contact motion control provide a brand-new strategy to create the next generation of intelligent optical materials.

And the article was included in Chemosphere in 2020.HPLC of Formula: 5137-55-3 The following contents are mentioned in the article:

Determining bioavailable trace concentrations of mercury (Hg) in water is still a challenging anal. task. In this study, we report a methodol. for determining labile Hg in natural waters using newly developed sorbents. Silicon dioxide at a nanoparticle range (Si-np) and cellulose powder at a microparticle range (Cel-p), both modified with the ionic liquid trioctylmethylammonium thiosalicylate (TOMATS), have been tested as sorbents (sorb-TOMATS) for Hg(II) uptake from solution These novel sorb-TOMATS materials were characterized, and parameters affecting the uptake were examined A similar Hg(II) uptake efficiency (97%) and binding capacity (9 mg Hg/g) was obtained for both sorb-TOMATS, while only a 25% of Hg(II) was taken up using non-impregnated materials. Moreover, these sorb-TOMATS were effectively embedded in agarose gel and were tested as a novel binding phase for the Diffusive Gradients in Thin Films (DGT) technique. Research revealed Si(np)-TOMATS sorbent as a suitable binding phase in the DGT technique for Hg(II) measurements, since it also allowed the efficient elution of the bound Hg(II). This new binding phase showed strong linear correlation between the accumulated Hg(II) mass and deployment time, which is in agreement with the DGT principle. In summary, this novel sorbent has a great potential to improve Hg monitoring in natural waters when integrated it in the DGT design. 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).

Several important parameters influencing extraction efficiency were investigated and optimized, including the type and volume of extractant in ultrasound stage, sonication time, the type and volume of D. E. S, sample solution pH and effect of salt addition Under optimal exptl. conditions, the method showed good linearity with correlation coefficients (R²) of 0.9985 – 0.9991 in the linear range of 4-1500μg kg^-1, low limits of detection of 1.5-2μg kg^-1 and acceptable extraction recoveries in the range of 76-92%. Enrichment factor was in the range of 95-115.

In situ product recovery (ISPR), in the form of an extractive fermentation process, can increase productivity and product titers in the sustainable production of platform chems. To establish a guideline for the development of industrially relevant production processes for such bio-based compounds, a wide screening was performed, mapping the potential of an extensive range of solvents and solvent mixtures Besides solvent biocompatibility with Saccharomyces cerevisiae, distribution coefficients of three organic acids (protocatechuic acid, adipic acid and para-aminobenzoic acid) and four fragrance compounds (2-phenylethanol, geraniol, trans-cinnamaldehyde and β-ionone) were determined While for highly hydrophobic fragrance compounds, multiple pure solvents were identified that were able to extract more than 98%, reactive extraction mixtures were proven effective for more challenging compounds including organic acids and hydrophilic alcs. For example, a reactive mixture consisting of 12.5% of the extractant CYTOP 503 in canola oil was found to be biocompatible and showed superior extraction efficiency for the challenging compounds as compared to any biocompatible single solvent. This mapping of biocompatible solvents and solvent mixtures for the extraction of various classes of industrial platform chems. can be a tremendous step forward in the development of extractive fermentations This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Recommanded Product: 5137-55-3).

And the article was included in International Journal of Biological Macromolecules in 2020.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

Cellulose, the most abundant feedstock of chems. and energy is extracted from various agro-industrial wastes, such as sugarcane bagasse (SB). Pretreatment of SB with ionic liquids improves extraction of cellulose, yet the use of ionic liquid is hindered by its high cost. In this study, cellulose was extracted from SB pretreated with methyltrioctylammonium chloride under relatively mild conditions. The extracted cellulose from pretreated SB (PTB) and untreated SB (UTB) was characterized by SEM and FTIR. Fermentation of cellulose extracted from PTB by a thermophilic bacterium, Bacillus aestuarii UE25, yielded 245.16% higher titers of cellulase than cellulose extracted from UTB. The recyclability of the IL was assessed to make the pretreatment process cost effective and was monitored through TLC and FTIR. The results of this research demonstrated the potential of ionic liquid pretreated SB for cellulose extraction and for its subsequent utilization in thermostable cellulase production 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).
