ESR study of the dynamics of adsorbed nitroxide radicals on porous surfaces in the dehydration process

The dynamics of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy (Tempyo), 4-oxo-2,2,6,6-tetramethyl-1-piperinyloxy (4-oxo-Tempo) and 4-acetamide-2,2,6,6-tetramethyl-1-piperidin-yloxy (4-acetamide-Tempo) nitroxide radicals in aqueous solutions adsorbed on hydrophilic and hydrophobic SiO2, Al2O3 and NaY zeolites with respect to dehydration degree were studied by ESR spectroscopy. The viscosity and the correlation times for the rotational motion of the adsorbed radicals depend on the dehydration degree, the nature of the support surfaces and the characteristics of the spin probe molecules.

Co-pyrolysis of textile dyeing sludge and red wood waste in a continuously operated auger reactor under microwave irradiation

The eco-friendly disposal of textile dyeing sludge (TDS) has become a worldwide environmental issue due to their complexity and toxicity. In this study, co-pyrolysis of TDS and red wood waste (RWW) in a continuously operated auger reactor under microwave irradiation was investigated, which was more environmentally friendly and created higher value added products. Effects of pyrolysis temperature and RWW ratio were studied to evaluate product distribution and properties. Increase of temperature and RWW ratio resulted in decrease in char yield and increase in gas yield. The contents of CO, CH4, and H-2 increased significantly with RWW ratio increased at 650 degrees C. The content of pyridines, amines, and nitriles enhanced sharply with increasing temperature from 450 to 750 degrees C. Co-pyrolysis promoted the Maillard reaction and cracking of nitrogen-containing pigments, forming large quantities of N-heterocyclics in bio-oil. Sludge char obtained by pyrolysis of TDS at 650 degrees C had a greater sulfur retention ability than chars from co-pyrolysis. The highest methylene blue number (372.25 mg/g) and iodine adsorption value (332.42 mg/g) were achieved from TDS and biochar (750 degrees C, 30 wt% RWW ratio), respectively. Fe(III) in Fe2O3 was reduced to Fe(II) in Fe3O4 and further partially reduced to metallic Fe in biochar. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis and characterization of a crosslinked membrane based on sulfonated poly(aryl ether sulfone) and sulfonated polyvinyl alcohol applied in direct methanol fuel cells

Vinyl-terminated sulfonated poly (arylene ether sulfone) (VSPAES) and sulfonated polyvinyl alcohol containing vinyl group (VSPVA) have been prepared. The VSPVA and VSPAES were crosslinked by adding AIBN as initiator. The results of FT-IR and H-1-NMR indicated the existence of sulfonic acid groups and crosslinked structure in these crosslinked membranes. The microphase structures of the membranes are analyzed by SEM. The proton conductivities of membranes were above 10 mS cm(-1), which indicated that it basically meet the needs of fuel cells. The methanol permeability coefficients of CSPAES membrane is 2.8×10(-7) cm(2) s(-1), remarkably lower than neat SPAES (8.5×10(-7) cm(2) s(-1)) and Nafion117 (14.1×10(-7) cm(2) s(-1)). Moreover, the proton selecticity of CSPAES membrane is close to 2 times higher than that of Nafion 117 membrane. The crosslinked membrane showed better stability than the linear SPAES membrane.

Synthetic Processes toward Nitriles without the Use of Cyanide: A Biocatalytic Concept Based on Dehydration of Aldoximes in Water

While belonging to the most fundamental functional groups, nitriles represent a class of compound that still raises challenges in terms of an efficient, cost-effective, general and, at the same time, sustainable way for their synthesis. Complementing existing chemical routes, recently a cyanide-free enzymatic process technology based on the use of an aldoxime dehydratase (Oxd) as a biocatalyst component has been developed and successfully applied for the synthesis of a range of nitrile products. In these biotransformations, the Oxd enzymes catalyze the dehydration of aldoximes as readily available substrates to the nitrile products. Herein, these developments with such enzymes are summarized, with a strong focus on synthetic applications. It is demonstrated that this biocatalytic technology has the potential to cross the bridge between the production of fine chemicals and pharmaceuticals, on one hand, and bulk and commodity chemicals, on the other.

Synthetic Studies on Cyclocitrinol: Construction of the ABC Ring System Based on Epoxy-Nitrile Cyclization

The stereoselective synthesis of a model compound containing the ABC ring system of cyclocitrinol was accomplished. After connecting a C ring allyltitanium segment with an A ring bi-cyclo[4.1.0]heptanone segment, the seven-membered B ring moiety was constructed by an intramolecular cyclization reaction of an epoxy nitrile. The enone moiety was introduced through an oxidative decyanation reaction, and the bicyclo[4.4.1]undecane skeleton with the highly strained olefin moiety was formed through a ring-opening reaction of the bicyclo[4.1.0]heptane substructure.

Cross-Linking of Rubber Matrices with Dicumyl Peroxide and Zinc Dimethacrylate. Part I: Effect of Co-Agent Content

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.

Iron-Catalyzed Carbenoid-Transfer Reactions of Vinyl Sulfoxonium Ylides: An Experimental and Computational Study

A method for the generation of unprecedented vinyl carbenoids from sulfoxonium ylides has been developed and applied in the synthesis of a diverse array of heterocycles such as indolizines, pyrroles, 3-pyrrolin-2-ones, and furans. The reactions proceed by FeBr2 catalysis under mild reaction conditions with a broad substrate scope. A reaction pathway involving iron carbenoids is proposed based on a series of control experiments and DFT calculations.

Tribological properties of hydrogenated nitrile rubber in confrontation with hard particles under different axial loads

The influence of different axial loads on the tribological properties of Hydrogenated Nitrile Rubber (HNBR) under oil-based mud containing hard particles is studied through experimental and theoretical approaches. Friction and wear tests were performed by using pin-on-disc friction pairs. The findings indicate that the tribological properties of HNBR vary with axial load and wear time. The total friction coefficient can be divided into an adhesion term, a hysteresis term and an abrasive term through the analysis of tribological mechanism. The hysteresis term is due to micro-strain on the HNBR surface and overall deformation of the HNBR specimen. The variation of tribological properties can be well explained through the above theory and the hysteresis term is the main influence factor.
