Polyoxymethylene dimethyl ethers (PODE, with the formula of CH3O-(CH2O)(n)-CH3), as a promising environmentally benign diesel fuel or additive with an enormous potential in the reduction of soot and NIC, emissions, can be efficiently synthesized from methanol derivatives such as dimethoxymethane (DMM) and trioxymethylene (TOM), which requests a proper catalyst of high performance. In this work, the catalytic performance of graphene oxide (GO) in the synthesis of PODEn as well as its relation to the catalyst structure was thoroughly investigated. The results indicate that GO is an excellent catalyst in the synthesis of PODEn from DMM and TOM; a TOM conversion of 94.6% and selectivity of 86.0% to PODE2-8 are achieved under mild reaction conditions, which is superior to the majority of the state-of-the-art catalysts. Meanwhile, the active species and characteristic layer structure of GO sheets catalytically responsible for PODEn formation were discriminated through selectively removing certain surface functional groups, thermally annealing at different temperatures, and carefully comparing with a series of model compounds. The results illustrate that the superior catalytic performance of GO in the PODEn synthesis should be ascribed to a synergy between the surface sulfonyl, hydroxyl and carboxyl groups present on the GO surface and the unique layered structure of GO sheets, wherein the surface sulfonyl groups act as the main active sites. The insights shown in this work are beneficial to a deep understanding on the catalytic principle of GO and development of efficient catalyst for the synthesis of PODEn.

A metal-free organocatalytic system has been developed for highly efficient benzylic C-H oxygenations of cyclic ethers using oxygen as an oxidant. This oxidation reaction utilizes alpha-angelica lactone as a low cost/low molecular weight catalyst. The optimized reaction conditions allow the synthesis of valued isocoumarins and phthalides from readily available precursors in good yields. Mechanistic studies indicate that the reaction pathway likely involves a radical process via a peroxide intermediate.

The activation of NLRP3 inflammasome is closely related to ischemic brain injury and inhibition of NLRP3 inflammasome activation may be a new therapeutic strategy for ischemic stroke. Our previous studies showed that ligustilide (LIG) had a dose-dependent neuroprotective effect on various models of cerebral ischemia and dementia in vivo and in vitro. CD21, a kind of phthalide derivative, was modified from LIG. In this study, we established a global cerebral ischemia-reperfusion model in mice by bilateral common carotid artery ligation (2VO), and explored the neuroprotective effect of CD21 and its anti-inflammatory mechanism on cerebral ischemia mice. CD21 significantly improved weight loss, neurobehavioral deficits and neurons loss in hippocampal CA1 and caudate putamen (CPu) subregions, which were induced by 2VO in mice. CD21 significantly inhibited the overactivation of astrocyte and microglia, and decreased the mRNA level of IL-6, TNF-alpha and IL-1 beta. Moreover, CD21 significantly inhibited the activation of TLR4/NF-kappa B signaling pathway mediated by HMGB1 and NLRP3/ASC/Caspase-1 signaling pathway mediated by Cathepsin B, thus inhibiting the activation of NLRP3 inflammasome. Our results demonstrated that CD21 may exert a neuroprotection by inhibiting NLRP3 inflammasome activation after cerebral ischemia. These findings provide a new strategy for the treatment of ischemic stroke.

A ligand-free iron-catalyzed method for the oxygenation of benzylic sp(3) C-H bonds by molecular oxygen (1 atm) using a thiyl radical as a cocatalyst has been developed. This transformation provides a facile access to amides, esters and ketones from readily accessible corresponding amines, ethers and alkanes. It features high regioselectivity, mild oxidative conditions and excellent functional group compatibility, providing good opportunities to the site-selective functionalization of complex molecules. Preliminary mechanistic studies suggest that this reaction may not undergo a benzylic cation intermediate pathway and the carbonyl oxygen atom in the products may be derived from molecular oxygen.

In this study, the biological activities and mode of action of 3-butylidene phthalide (3-BPH) were studied. 3-BPH had a superior efficiency against microsclerotia of Macrophomina phaseolina compared to the commercial fungicide tricyclazole. The microsclerotia formation and pigmentation were inhibited at 100 mu g/mL. Moreover, the fungicide exhibited in silico affinity toward trihydroxy naphthalene reductase (3HNR). Both 3-BPH and tricyclazole showed congruence in the orientation and interaction within the 3HNR active site. 3-BPH displayed a strong interaction with SER-164, TYR-178, and TYR-223, with estimated binding energy and inhibition constant of -6.78 kcal mol(-1), and Ki = 12.6 mu M, respectively. Furthermore, it showed in vitro and in silico inhibitory activity against Drosophila melanogaster acetylcholinesterase in a concentration-dependent manner with IC50 = 730 mu g/mL. It also impaired Galleria mellonella phenol oxidase enzyme, which corresponds with the insect’s immune system. Phytotoxicity of 3-BPH was evident against Lemna minor at 1000 mu g/mL; nevertheless, it was nontoxic at the concentrations inhibiting M. phaseolina microsclerotia and dark pigments suggest that it may be safe for use on other plants at low doses. Further assays are wanted to develop 3-BPH as a novel crop protection compound.

Plasma catalysis has been utilized in many environmental applications for removal of various hydrocarbons including tars. The aim of this work was to study the tars removal process by atmospheric pressure DBD non-thermal plasma generated in combination with packing materials of various composition and catalytic activity (TiO2, Pt/gamma Al2O3, BaTiO3, gamma Al2O3, ZrO2, glass beads), dielectric constant (5-4000), shape (spherical and cylindrical pellets and beads), size (3-5 mm in diameter, 3-8 mm in length), and specific surface area (37-150 m(2)/g). Naphthalene was chosen as a model tar compound. The experiments were performed at a temperature of 100 degrees C and a naphthalene initial concentration of approx. 3000 ppm, i.e., under conditions that are usually less favorable to achieve high removal efficiencies. For a given specific input energy of 320 J/L, naphthalene removal efficiency followed a sequence: TiO2 > Pt/gamma Al2O3 > ZrO2 > gamma Al2O3 > glass beads > BaTiO3 > plasma only. The efficiency increased with the increasing specific surface area of a given packing material, while its shape and size were also found to be important. By-products of naphthalene decomposition were analyzed by means of FTIR spectrometry and surface of packing materials by SEM analysis.

The present study analyses the thermowell system for monitoring temperatures in a fixed bed catalytic reactor for the highly exothermic partial oxidation of o-xylene to phthalic anhydride. Particle-resolved computational fluid dynamics (CFD) simulations are presented for the cases of randomly-packed spheres inside cylindrical tubes with tube-to-particle diameter ratios (N) of 3.96, 5.96 and 7.99. Results are obtained for each N value for cases with inner thermowell radius to outer tube radius ratios of 0.0 (no thermowell), 0.05, 0.1 and 0.2. Comparisons of radial void fraction and axial velocity profiles, axial pressure drop and axial temperature profiles under reaction conditions are presented. The presence of the thermowell did change the mass and heat transfer and reaction inside and around the particles, especially at the bed center. The configurations of catalyst particles were rearranged, leading to changes in voidage, flow and temperature profile. The axial temperature profiles from the thermowells differed from the profiles in the undisturbed beds. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Chemoselective hydrogenation of phthalic anhydride is regarded as the most promising route for producing downstream high-performance phthalide. A series of intermetallic cobalt-nickel silicide catalysts embedded in a carbon matrix (CoxNi2-xSi@C) with acid-tolerance prepared by microwave-assisted chemical vapor deposition have been investigated in this reaction system. Activity measurements show a remarkable positive synergistic effect, forming a volcano-shaped plot over the nominal Co metal fraction for CoxNi2-xSi@C catalysts with a peak at x = 1.5, which corresponds to a 4.5-fold enhancement of the yield of phthalide over Co2Si@C and a 2.0-fold enhancement over the Ni2Si@C monometallic silicide catalysts, which can be correlated with the interaction of cobalt-nickel and metal-silicon bonds. In addition, the cobalt-rich bimetallic silicide exhibits an equal activity to the reference noble metal catalysts (Au, Pd, and Pt) and a significantly higher activity than transition metal catalysts. Moreover, the bimetallic silicide as an intermetallic compound catalyst has demonstrated robust acid corrosion resistance compared to the corresponding metal catalysts.

Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC x GC-TOF-MS) was combined with conventional mono-dimensional GC-MS to differentiate Croatian virgin olive oils (VOO) according to variety and geographical origin, based on the profile of volatile aroma compounds isolated by HS-SPME. More than 1000 compounds were detected after untargeted profiling and 256 were identified or tentatively identified, providing one of the most detailed profiles of volatile aroma compounds in VOO up to date. Among them, 131 volatile compounds were significantly different across monovarietal VOOs, while 60 were found useful for the discrimination according to geographical origin. Many major lipoxygenase and minor non-lipoxygenase-generated compounds were shown to have discriminating ability with respect to both factors. Multivariate statistical analysis extracted twenty-one volatile markers with the highest discriminant power for varietal differentiation. The approach reported may have practical application in better understanding, defining, managing, and communicating the varietal or geographical typicity of monovarietal VOOs.
