Nanostructured crystalline metal oxides are in great demand in industrial processes due to their unique physicochem. properties and ionic liquids (ILs) are promising solvent for synthesizing such materials. Herein, we report an IL-assisted, facile, and environmental benign approach to synthesize rutile phase of ruthenium oxide (RuO₂) nanoplatelets (NPLs) structure with a size distribution of a few tens of nm. The key to this synthesis methodol. is the use of imidazolium-based ILs as solvents and binder in the ionothermal process. The obtained RuO₂ phase is thoroughly characterized by spectroscopic and microscopic techniques. Further, the material is used as electrocatalyst toward electrochem. energy storage and conversion in an alk. solution The platelet morphol. of RuO₂ exhibits excellent supercapacitor performance and its capacitance value is âˆ?200 F g^-1 in 1 M KOH solution Besides, the as-synthesized RuO₂ NPLs shows superior water oxidation and chlorine evolution processes at a minimal overpotential, i.e., 1.47 V in 1 M KOH and 1.5 V in 3 M KCl (pH 3) electrolyte, resp., exhibiting its tri-functional electrochem. behavior toward production of renewable energies. The present study demonstrates that single-step production of the NPL morphol. of RuO₂ has potential implications in the field of electrolysis and supercapacitors.

Ding, Haoshu published the artcilePyrolytic characteristics of Fushun oil shale and its by-products, Recommanded Product: 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Thermal Analysis and Calorimetry (2022), 147(8), 5255-5267, database is CAplus.

FTIR, TG-DTG, TG-FTIR, and Py-GC-MS were employed to investigate the similarities and differences in the pyrolytic characteristics of Fushun oil shale and its byproducts, i.e., semi-coke and residual. The semi-coke was obtained by slowly pyrolyzing the oil shale to 450°C. The residual was a solid residue prepared by completely extracting the semi-coke with a 1-butyl-3-methylimidazolium chloride and N-Me pyrrolidon mixture The pyrolysis of three samples is related to the cleavages of weak bonds (200-400°C), decomposition of major organic structures (400-600°C), and the cleavages of 3-4 kinds of chem. bonds. Gaussian fitting methods was used to fit the DTG curves to evaluate the contributions of various covalent bonds to the pyrolysis. The flash pyrolysis products and typical gaseous products were identified, showing the most outstanding performances of the aliphatic compounds The differences in the pyrolytic characteristics of three samples are mainly attributed to the diverse forms of thermal bitumen. The attendance of thermal bitumen in the semi-coke, especially its light components generated from oil shale pyrolysis, prompts the more active mass loss behaviors at relatively low temperatures, while the absence of thermal bitumen results in a fairly low mass loss of the residual.

Kosmulski, Marek published the artcileZeta potential in dispersions of titania nanoparticles in moderately polar solvents stabilized with anionic surfactants, Application of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Molecular Liquids (2022), 118972, database is CAplus.

Electrophoretic mobility of titania nanoparticles in ethane-1,2-diol and in propane-1,2-diol in the presence of SDS and sodium octadecylsulfate was measured. Several dispersions were acidified with HCl or alkalized with NaOH. Addition of acid resulted in pos. and addition of base resulted in neg. zeta potential. Anionic surfactants have moderate effect on the zeta potential. They enhanced neg. zeta potential, but their effect became significant at surfactant concentrations as high as 1 g/L. Sodium octadecylsulfate was more efficient than SDS in shifting the zeta potential to more neg. values.

Podder, Nirmalya published the artcileAerobic oxidation of 2-aminophenol catalysed by a series of mononuclear copper(II) complexes: phenoxazinone synthase-like activity and mechanistic study, Synthetic Route of 4760-35-4, the publication is New Journal of Chemistry, database is CAplus.

Three mononuclear copper(II) complexes of types [Cu(L¹)(Cl)₂]·MeOH (1·MeOH), [Cu(L²)(Cl)₂]·H₂O (2·H₂O) and [Cu(L³)(Cl)₂] (3) have been synthesized from three reduced Schiff base tridentate N₃ ligands, namely N-(pyridin-2-ylmethyl)quinolin-8-amine ([H₂]L¹), N-(1-methylbenzimidazol-2-ylmethyl)quinolin-8-amine ([H₂]L²), and N-(1-methylimidazol-2-ylmethyl)quinolin-8-amine ([H₂]L³), resp., having variable donor moieties. During metalation all three reduced Schiff base ligands undergo oxidative dehydrogenation in situ under aerobic conditions to yield the corresponding Schiff base ligated mononuclear copper(II) complexes. All complexes have been characterized using various spectroscopic techniques such as IR, HRMS-ESI, UV-vis, and EPR. Structural characterization of each complex by single crystal x-ray diffraction reveals that the coordination environment around the copper ion is distorted square pyramidal. The three complexes effectively catalyze the aerial oxidation of 2-aminophenol (H₂AP) to 2-amino-phenoxazine-3-one (APX), thus mimicking the catalytic function of the enzyme phenoxazinone synthase. Kinetic studies have been done to arrive at the following catalytic efficiency order: 3 â‰?2·H₂O > 1·MeOH. The observed trend can be explained by considering the structure-function relation of the catalytic activity. Intramol. charge distribution (valence tautomerism) within a complex-substrate adduct leads to the generation of a “Cu^I-(substrate radical)” tautomer. This phenomenon has been established by EPR spectroscopy, particularly using 2-anilino-4,6-di-tert-butylphenol (H₂AP^Ph,t-Bu, a structural analog of H₂AP) as a substrate. Such a “Cu^I-(substrate radical)” species is believed to promote dioxygen activation. The effects of temperature and pH on the reaction rates have been studied. Activation parameters (E_a, ΔH^{â€?/sup>, and ΔSâ€?/sup>) have been evaluated from temperature-dependent kinetic measurements. A plausible reaction pathway has been proposed on the basis of stoichiometry determination, spectroscopic data and kinetic anal.}

Li, Shiye published the artcileIonic liquid-modulated aerobic oxidation of isoeugenol and β-caryophyllene via nanoscale Cu-MOFs under mild conditions, Safety of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Molecular Catalysis (2022), 112416, database is CAplus.

Novel synergistic systems based on Cu-1,3,5-benzenetricarboxylate and ionic liquid are developed for the convenient conversion of renewable olefins, isoeugenol and β-caryophyllene, under very mild conditions (i.e. 313 K and 1 atm O₂). Using acidic ionic liquid [C₄mim][HSO₄] (5.0 mol%) as co-catalyst, Cu₃(BTC)₂-Lauric acid (LA) afforded high selectivity (95.8%) and excellent yield (86.3%) for vanillin Me ketone during the aerobic oxidation of isoeugenol. In comparison, 91.1% selectivity for vanillin together with 28.9% conversion of isoeugenol was obtained over Cu₃(BTC)₂-LA in the presence of amino acid ionic liquid, [C₄mim][Ala]. Addnl., 91.3% selectivity and 86.5% yield for β-caryophyllene epoxide were provided by Cu₃(BTC)₂-LA with the aid of neutral [C₄mim]Cl (5.0 mol%), indicating the importance of different types of ILs in tuning the microenvironments of designed Cu₃(BTC)₂-LA nanosystems. Simultaneously, Cu₃(BTC)₂-LA/IL showed superior stability during above-mentioned transformations, as verified by TEM, FT-IR and XRD analyses. Insights into the synergistic free radical routes were supported by fluorescence and DRUV-Vis characterizations.

Sulaimon, Aliyu Adebayo published the artcilePredicting naphthenate precipitation and evaluating the effect of ionic liquids on its deposition, Related Products of imidazoles-derivatives, the publication is Journal of Petroleum Science & Engineering (2022), 109865, database is CAplus.

Naphthenic acids that are naturally carboxylic compounds contained in heavy crude oil are the main source of corrosion and blockage in a crude oil pipeline. The blockage is due to the formation of naphthenate deposits through a reaction of naphthenic acid with metal ions present in the crude oil. In the present study, model oil is used to evaluate the effect of water cut in the range of 10%-90%, brine pH in the range of 6-10, Ca²⁺ concentration in the range of 0.5%-2.5% and temperature in the range of 30 °C-60 °C towards naphthenate deposition with the aid of response surface methodol. NMR (NMR) and Fourier Transform IR (FTIR) were used to evaluate the structure of the naphthenic acids used. Results show that Ca²⁺ concentration contributes mostly to the naphthenate deposition, followed by brine pH, water cut and temperature Two math. models were developed to predict the final pH of the oil-brine system and the mass of precipitates with average relative errors (AREs) of 0.0328 and 0.0325 resp. The effects of two ionic liquids (ILs), 1-ethyl-3-methylimidazolium chloride (EMIM-Cl) and 1-butyl-3-methylimidazolium chloride (BMIM-Cl), on naphthenates precipitation, were also evaluated. Anal. showed that both ILs can reduce the amount of naphthenate deposited, with the BMIM-Cl showing better performance than the EMIM-Cl.
