The present article describes the synthesis of a new magnetic polyacrylonitrile-based Pd catalyst involving polyacrylonitrile modified via 2-aminopyridine as an efficient support to immobilize Pd nanoparticles. The simple reusability, easy separation and high stability of this Pd complex make it an excellent candidate to generate a C-O bond via Ph-X activation which is a really important subject in achieving biologically active compounds. It is worth to note access to good and high yields as well as broad substrate scope have resulted from superior reactivity of this catalyst complex. Furthermore, the structure of the magnetic polyacrylonitrile-based heterogeneous catalyst was characterized by fourier transmission infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), X-ray diffraction (XRD). Also, its thermal properties were studied by thermogravimetric analysis (TGA). (C) 2020 Elsevier B.V. All rights reserved.

Electrocatalytic hydrogenation (ECH) provides a green route to upgrade oxygenated bio-oil under mild conditions, but is still challenged with the issues of low working current density (<60 mA cm(-2)) and low faradaic efficiency (usually 20-60%) that seriously hinder its practical applications. Herein, we present a dual-catalyst electrochemical route that achieves extremely high faradaic efficiency (>99% for many chemicals) and high working current density (up to 800 mA cm(-2)) in the hydrogenation of model bio-oil compounds. More importantly, efficient deoxygenation to alkanes, often thought to be very difficult in conventional ECH, was achieved in the aqueous electrolysis. The dual-catalyst system consists of a suspended noble-metal catalyst and soluble polyoxometalate (POM). The theoretical calculations indicate that the POM functions as a superacid, changing the common hydrogenation route to a carbocation mechanism and resulting in effective electrolytic deoxygenation of oxygenates. Because no current flows through the catalyst, even a non-conductive catalyst can be used, which provides a great opportunity for extension to general applications.

Bis(NHC)-Pd-catalyzed competitive asymmetrical C-C*C-C, C-C*C-O, C-C*C-N, and O-C*C-N cross-coupling reactions were performed via the one-pot strategy in the presence of a new ionic liquid, which played the roles of solvent, base, and ligand simultaneously. The ionic liquid was prepared based on a methyl imidazolium moiety with hydroxyl counter anions via a Hofmann elimination on a 1,3,5-triazine framework (TAIm[OH]). Pd ions could be efficiently coordinated through the bis(NHC)-ligand moiety in the ionic liquid. Based on differences in the competitive kinetics of C-C cross-coupling reactions (Heck, Suzuki, and Sonogashira) with C-N and C-O cross-coupling reactions, and also differences in the kinetics of aryl halides, the coupling reactions could be selectively performed with a low amount of by-products. The competitive cross-coupling reactions were thus performed with high selectivity under mild reaction conditions.

The kinetics of the hydrolysis of heavy hydrocarbons in supercritical water were probed using density function theory (DFT) and molecular dynamics (MD) simulation of the probe molecule dibenzyl ether (DBE). The focus of the study was the effect of solvent on the reaction kinetics. The DFT studies were aimed at the estimation of the kinetic parameters and the transition-state structure, whereas the MD studies were aimed at the estimation of the solubility parameters used in a model of the reaction nonidealities. Both DFT results, with an imposed dielectric constant to represent the solvent polarity, and the MD results, where the solubility parameter was estimated, indicated that the fastest kinetics were attained at the highest polarity. The COSMO-sigma profiles obtained from DFT calculations revealed that the transition state for the reaction was more polar than the reactants. The MD simulation provided estimates of the solubility parameters of reactants and the transition state, which allowed a complementary estimate of the rate of the reaction in a supercritical water solution via transition-state theory. The rates of reaction estimated from DFT and MD calculations at 674 K were in fair agreement with experimental data at low values of the dielectric constant.

Superparamagnetic nanoparticles (SPIONs) can be used as nuclear magnetic resonance (NMR) signal enhancement agents for petroleum exploration. This enhancement effect is uniform if SPIONs are monodisperse in size and in composition; yet it is challenging to synthesize mono disperse particles that do not aggregate in high salinity petroleum brine. Here, we report a method to synthesize individual SPIONs coated with tunable surface coating densities of poly(2-acrylamido-2-methyl-1-propanesulfonic acid (pAMPS) with a catechol end-group (pAMPS*). To establish parameters under which pAMPS*-coated SPIONS do not aggregate, we compared computational predictions with experimental results for variations in pAMPS* chain length and surface coverage. Using this combined theoretical and experimental approach, we show that singly dispersed SPIONs remained stabilized in petroleum brine for up to 75 h with high surface density pAMPS*.

This paper describes the pyrolysis of Poplar fluff (from Populus alba) using on-line apparatus, and carbonization process at 850 degrees C using the fixed bed reactor. Characteristics of pyrolysis products were examined. Elemental and chemical analyses were shown that Poplar fluff has higher energy content characterized by increased content of fibrous structure (particularly cellulose). Independent parallel reactions model very well describes devolatilization process. It was found that increased amount of extractives can significantly affect on increased release of light gaseous products, but declining hydrocarbons, mostly the alkanes. Liquid product is mainly composed of phenolics, aldehydes, acids, esters and ketones. The carbonization process produces the great abundance of polycyclic aromatic hydrocarbons (PAH’s), where naphthalene is the most abundant. Mechanism for PAH’s formation was suggested. This study represents the first step in a much wider and more comprehensive way in thermal conversion processes of this type of fuel.

Synthesis of size-controlled anisotropic magnetite (Fe3O4) nanoparticles allows designing next-generation magnetic nanosystems with predetermined magnetic properties suited for particular applications in the biomedical, information, and environment fields. In this work, we report a reproducible and economical approach for fabricating anisotropic Fe3O4 nanoparticles via the thermal decomposition method. Controlling the reaction environment, i.e. the degassing pressure, is essential to obtain the reproducible synthesis of anisotropic Fe3O4 nanoparticles along with monodispersity in the size and shape. At low degassing pressure, Fe3O4 nanocubes are formed, and an increase in degassing pressure leads to the formation of Fe3O4 octahedral nanoparticles. To achieve good reproducibility (with respect to size and shape) between different batches, our finding reveals the importance of maintaing the same degassing pressure. The size of the anisotropic Fe3O4 nanoparticles can be varied by changing the heating rate and the solvent amount. The amount of solvent has also an influence on the shape of the nanoparticles, and Fe3O4 nanoparticles of flower morphology are obtained at a high solvent amount. The work also provides new conceptual fundamental insights into understanding the growth mechanism of anisotropic Fe3O4 nanoparticles and thus advancing the field of materials chemistry for rationally designing anisotropic nanoparticles with tunable magnetic properties.

COA of Formula: C14H14O. The Name is Benzyl ether. Through research, I have a further understanding and discovery of 103-50-4.

Nano ferrites (AFe(2)O(4), A = Zn, Co, Mn, Cu) were supported on the surface of gamma-Al2O3 support by hydrothermal synthesis to prepare a series of novel composite catalysts (AFe(2)O(4)/gamma-Al2O3) for catalytic ozonation for elimination of high concentration toluene at ambient temperature. The characterization results showed that the high-purity nano-AFe(2)O(4) particles were uniformly loaded on mesoporous gamma-Al2O3. Further, it was confirmed that among the several catalysts prepared, the amount of oxygen vacancies (O-vs), Lewis acid sites (LAS), and BrOnsted acid sites (BAS) of the ZnFe2O4/gamma-Al2O3 catalyst were the highest. This meant that the ZnFe2O4/gamma-Al2O3 catalyst had a strong adsorption capacity for toluene and ozone (O-3), and had a strong catalytic activity. When the temperature was 293 K and the space velocity was 1500 h(-1), the mol ratio of O-3 to toluene was 6, the degradation rate of toluene (600 mg m(-3)) can reach an optimum of 99.8%. The results of electron paramagnetic resonance (EPR) and Fourier infrared (FT-IR) proved superoxide radicals and hydroxyl radicals by catalytic ozonation. Moreover, the GC-MS analysis results indicated that the toluene degradation began with the oxidation of methyl groups on the benzene ring, eventually producing CO2 and H2O. After repeated experiments, the toluene degradation rate remained stable, and the residual content of O-3 in each litre of produced gas was less than 1 mg L-1, thereby indicating that the ZnFe2O4/gamma-Al2O3 catalyst had excellent reusability and showed great potential for the treatment of toluene waste gas.

Background: Polybrominated diphenyl ethers (PBDEs) are dangerous for the environment and human health because of their persistent organic pollutant (POP) characteristics, which have attracted extensive research attention. Raman spectroscopy is a simple highly sensitive detection operation. This study was performed to obtain environmentally friendly non-POP PBDE derivatives with simple detection-based molecular design and provide theoretical support for establishing enhanced Raman spectroscopic detection techniques. Methods: A three-dimensional quantitative structure-activity relationship (3DQSAR) pharmacophore model of characteristic PBDE Raman spectral was established using 20 and 10 PBDEs as training and test sets, respectively. Full-factor experimental design was used to modify representative commercial PBDEs, and their flame retardancy and POP characteristics were evaluated. Results: The pharmacophore model (Hypol) exhibited good predictive ability with the largest correlation coefficient (R-2) of 0.88, the smallest root mean square (RMS) value of 0.231, and total cost of 81.488 with a configuration value of 12.56 (<17).74 monosubstituted and disubstituted PBDE derivatives were obtained based on the Hypo 1 pharmacophore model and full-factor experimental design auxiliary. Twenty PBDE derivatives were screened, and their flame-retardant capabilities were enhanced and their migration and bio-concentration were reduced (log(K-OW) <5), with unchanged toxicity and high biodegradability. The Raman spectral intensities increased up to 380%. In addition, interference analysis of the Raman peaks by group frequency indicated that the 20 PBDE derivatives were easily detected with no interference in gaseous environments. Conclusion: Nine pharmacophore models were constructed in this study; Hypo 1 was the most accurate. Twenty PBDE derivatives showed Raman spectral intensities increased up to 380%; these were classified as new non-POP environmentally friendly flame retardants with low toxicity, low migration, good biodegradability, and low bio-concentrations. 2D QSAR analysis showed that the most positive Milliken charge and lowest occupied orbital energy were the main contributors to the PBDE Raman spectral intensities. Raman peak analysis revealed no interference between the derivatives in gaseous environments. Recommanded Product: Diphenyl oxide.

Polycarbonate (PC) is an engineering thermoplastic that is widely used in electrical and electronic equipment. This plastic often contains tetrabromobisphenol A (TBBA), the most common brominated flame retardant. Thermal degradation of the PC-TBBA leads to generation of numerous bromo-organic products in the pyrolytic oil, hindering its appropriate utilization, as well as corrosive hydrogen bromide gas. The purpose of this study was to experimentally investigate and compare the pyrolysis products of PC-TBBA and PC-TBBA + Cu2O at various temperatures, with an emphasis on the yield and distribution of brominated compounds. In pyrolysis of PC-TBBA + Cu2O, at the maximum degradation temperature (600 degrees C), as much as 86% of total Br was trapped in the residue, while 3% and 11% were distributed in the condensate and gas fractions, respectively. In contrast, the distribution of Br from non-catalytic pyrolysis of PC-TBBA (600 degrees C) was 0.5% residue, 40% condensate, and 60% gas. The results of this study revealed that in the presence of Cu2O, organo-bromine products were most likely involved in Ullman-type coupling reactions, leading to early cross-linking of the polymer network that efficiently hinders their vaporization. HBr in the gas fraction was suppressed due to effective fixation of bromine in residue in the form of CuBr.
