We investigated the properties and catalytic activity of zeolites with MWW topology obtained by unprecedented liquid exfoliation of the MCM-56 zeolite into solutions of monolayers and isolation/reassembly of the dispersed layers by various methods, with optional purification by dialysis or ammonium exchange. The layers were recovered by flocculation with alcohol or ammonium nitrate and freeze-drying. Flocculation alone, even with ammonium nitrate, did not ensure removal of residual sodium cations resulting in catalysts with low activity. Dialysis of the solutions with dispersed monolayers proved to be efficient in removing sodium cations and preserving microporosity. The monolayers were also isolated as solids by freeze-drying. The highest BET area and pore volume obtained with the freeze-dried sample confirmed lyophilization efficiency in preserving layer structure. The applied test reaction, Friedel-Crafts alkylation of mesitylene, showed high benzyl alcohol conversion due to increased concentration of accessible acid centers caused by the presence of secondary mesoporosity. The applied treatments did not change the acid strength of the external acid sites, which are the most important ones for converting bulky organic molecules. Zeolite acidity was not degraded in the course of exfoliation into monolayers, showing the potential of such colloid dispersions for the formation of active catalysts.

An efficient and simple approach for the direct synthesis of aryl and heteroaryl sulfonic esters was developed using DMS and DES as alkoxysulfonylation reagents. The reaction is operationally simple and scalable. This protocol does not require solvent, expensive catalysts, base, ligand additives or other reagents. A wide range of sulfonic esters were synthesized in moderate to good chemical yields. This method has the advantage of low cost, facile and tolerated a wide range of substrates.

The Kamlet and Taft solvent basicity parameter, beta, and solvent polarity/polarizability parameter, pi*, were analyzed in terms of properties of the solvent molecules derived from computational chemistry. The analysis of beta, using a larger data set, confirms earlier conclusions that, for aprotic solvents, the basicity is determined by the partial charge on the most negative atom of the solvent molecule and by the energy of the highest energy molecular orbital associated with the donor site. For alcohols and nitrogen bases containing N-H moieties, the beta values deviate systematically from those for the non-hydrogen bonding solvents. Analysis of the polarity/polarizability parameter, pi*, shows that it depends directly on the dipole moment, and quadrupolar amplitude of the solvent and on the energy of the highest occupied molecular orbital, but decreases linearly with increasing solvent polarizability.

Pyridazinone analogues have been known to be potential candidates for anticonvulsant agents. We have identified several pyridazinone-based anticonvulsant agents. As a continuation to our previous research, a series of hybrid pyridazinone-thiazole connected through amide linkage were designed and synthesized. Among these, compound SP-5F demonstrated significant anticonvulsant activity with median effective dose of 24.38 mg/kg (MES) and 88.23 mg/kg (scPTz). Results of GABA estimation showed a marked increase in the GABA level when compared with control. Molecular docking studies at the active site of GABA receptor, further confirmed the GABA modulatory effects of SP-5F.

Annual air samples were collected at various sites in the Fildes Peninsula, West Antarctica from December 2010 to January 2018 using XAD-2 resin passive air samplers to investigate concentrations, temporal trends and potential sources of persistent organic pollutants (POPs) in Antarctic air. Relatively low concentrations of polychlorinated biphenyls (PCBs) (Sigma(19)PCBs: 1.5-29.7 pg/m(3)), polybrominated diphenyl ethers (PBDEs) (Sigma 12PBDEs: 0.2-2.9 pg/m(3)) and organochlorine pesticides (OCPs) (Sigma(13)OCPs: 101-278 pg/m(3)) were found in the atmosphere of West Antarctica. PCB-11, BDE-47 and hexachlorobenzene (HCB) were the predominant compounds in the atmosphere. The concentrations of PCBs, HCHs, DDTs and endosulfans were found to show decreasing temporal trends, whereas uniform temporal trends were observed for HCB. The atmospheric half-life values for PCBs, HCHs, DDTs and endosulfans in Antarctic air were estimated for the first time, using regressions of the natural logarithm of the concentrations versus the number of years, obtaining the values of 2.0, 2.0, 2.4 and 1.2 year, respectively. An increasing ratio of alpha-HCH/gamma-HCH indicated long residence time for alpha-HCH and possible transformation of gamma-HCH to alpha-HCH in the atmosphere. The ratios of p,p’-DDT/p,p’-DDE were mostly lower than unity in this study, which could be attributed to aged sources. It was found that long-range atmospheric transport was still considered to be the main contributing factor to the atmospheric levels of the POPs in West Antarctica whereas the contribution of human activities at the Chinese Great Wall Station was minor. The results of this study give a view on the most recent temporal trends and provide new insights regarding the occurrence of various POPs in the Antarctic atmosphere. (C) 2019 Elsevier Ltd.

The direct sulfonation is a cheap process but introduces the valuable sulfonic acid groups onto the backbone of aromatic polymers for proton exchange membrane fuel cell applications. However, the chain-scission during sulfonation degrades the polymer backbone by cleavage of the linkages between the arylene rings. If the sulfonation is conducted at a relatively high temperature for long time, the degradation may be significant. In this paper, the chain-scission mechanisms of the typical aromatic polymers are studied in terms of transition states and activation energies using density functional theory calculations, and the improvement of the overall performances of sulfonated proton conducting materials is discussed.

Bulk chemicals produced from renewable resources are receiving considerable attention due to the increase in sustainable practices. In this study, a novel, efficient, and sustainable strategy has been proposed to produce versatile petroleum based monophenols from the natural aromatic polymer, lignin, via the selective cleavage of its specific chemical linkages by a cost-effective catalyst, Ni/MgO. The results demonstrate that 93.4% of lignin is converted, yielding 15.0% monophenols in the presence of 20% Ni/MgO. Importantly, 42.3% of these volatile chemicals are found to be 4-ethyl phenol (the yield is 6.31%), a widely used fine chemical currently obtained from the petrochemical industry. Further comparative investigations on the raw and recovered lignin using heteronuclear single quantum correlation-nuclear magnetic resonance (HSQC-NMR), Fourier transform infrared (FT-IR), quantitative C-13 NMR, and the alkaline nitrobenzene oxidation method reveal that the selective breakage of the ester bond between the p-hydroxyphenyl structural unit and the other fragments followed by decarboxylation is responsible for the good performance of the 4-ethyl phenol formation process. Therefore, the results of this work would provide new insights for producing value-added petrochemicals from renewable lignin.

The Pd/C catalysts are widely used in synthesis of fine chemicals in industry, but their production suffers from a complicated two-step process involving impregnation and reduction, and requires large amounts of solvents and reductant, which would lead to a series of issues such as time consumption, resource waste and environmental pollution. Herein, ultra-small Pd nanoparticles uniformly anchored on carbon nanotubes (Pd/CNTs) were synthesized by using a one-pot and low-temperature reduction strategy. The present process/technology is very sensitive to and controlled by the supports and solvents, and the carbon support and acetic acid synergistically play crucial and decisive roles in the fast production of Pd/C catalysts. Also, the used solvents can be recycled and reutilized, which meets the requirements of sustainable chemistry and green economy. When the as-obtained Pd/CNTs catalyst was used to catalyze the oxidation of benzyl alcohol to benzaldehyde, it achieved a conversion efficiency as high as 99.3 % and a high selectivity up to >99.9 %. The simple, scalable and environmentally friendly strategy can be extended to anchor Pd nanoparticles on various carbon substrates, which sheds a new light on the synthesis of Pd/C catalysts.

Silica-coated magnetite nanoparticles were functionalized with aminopropylsilyl groups and then condensed with 2-benzoylthiophene to produce a NS Schiff base chelating ligand for complexation of Cu (II) species. Characterization of the synthesized nanocomposite was performed by several spectroscopic and microscopic analyses to reveal its physical and chemical properties. It was applied as an efficient heterogeneous catalyst in promoting O-arylation reaction of phenols with aryl halides for the synthesis of diaryl ethers using deep eutectic solvents (DESs) based on choline chloride as reaction media. The catalyst and DES could be easily recycled up to five times without a significant effect on the reaction progress. The use of green and recoverable reaction medium, easy work-up, easy separation of the catalyst with the assistance of an external magnetic field, short reaction times, and high yields of products are the main merits of this protocol.
