Diethylene Glycol/NaBr Catalyzed CO2 Insertion into Terminal Epoxides: From Batch to Continuous Flow

CO2 insertion reactions on terminal epoxides (styrene oxide, 1,2-epoxyhexane and butyl glycidyl ether) were performed in a binary homogeneous mixture comprising NaBr as the nucleophilic catalyst and diethylene glycol (DEG) as both solvent and catalyst activator (cation coordinating agent). The reaction protocol was initially studied under batch conditions either in autoclaves and glass reactors: quantitative formation of the cyclic organic carbonate products (COCs) were achieved at T=100 degrees C and p(0)(CO2)=1-40 bar. The process was then transferred to continuous-flow (CF) mode. The effects of the reaction parameters (T, p(CO2), catalyst loading, and flow rates) were studied using microfluidic reactors of capacities variable from 7.85 . 10(-2) to 0.157 cm(3). Albeit the CF reaction took place at T=220 degrees C and 120 bar, CF improved the productivity and allowed catalyst recycle through a semi-continuous extraction procedure. For the model case of 1,2-epoxyhexane, the (non-optimized) rate of formation of the corresponding carbonate, 4-butyl-1,3-dioxolan-2-one, was increased up to 27.6 mmol h(-1) equiv.(-1), a value 2.5 higher than in the batch mode. Moreover, the NaBr/DEG mixture was reusable without loss of performance for at least 4 subsequent CF-tests.

Surface and foam property of perfluoroalkyl polyoxyethylene ether phosphate salt in aqueous-ethanol system

Foam is used in many fields with excellent performance. Moreover, disinfectants with ethanol as the main ingredient have increasingly been used in people’s lives. However, the foam research of an ethanol water mixed system is still in the initial stage. In this work, a perfluoroalkyl polyoxyethylene ether phosphate salt surfactant (FEP-Na) was synthesized through a new molecular design. The surfactant has good interfacial adsorption behavior in 50% ethanol-water mixing system, and the approximately spherical aggregates are observed in the volume phase of the solution. Moreover, FEP-Na showed good foaming property in 50% ethanol-water mixed solution. Interestingly, high concentration solutions with high surface activity have lower foam stability. And under the microscope, we see that the bubble burst is dominated by the phenomenon of coalescence. In this regard, we explain the mechanism of foam stability by electrostatic double layer theory and interfacial dilation rheology. It provides a new choice for the synthesis of foaming agent in the ethanol-water mixed system at a concentration of 50%. (c) 2020 The Korean Society of Industrial and Engineering Chemistry.

Y Enhancing separation efficiency in European syngas industry by using zeolites

Syngas is traditionally used in industry for production of fuels in the kerosene, gasoline and diesel range via Fischer-Tropsch, for the manufacture of bulk chemicals like ammonia, methanol and dimethyl ether and for synthesis of a whole array of fine chemicals. The carbon monoxide/hydrogen ratio of the syngas is an important design variable to maximize production of these compounds. Therefore, the search of effective processes that enable said ratio adjustment as well as individual compound purification is an essential and ongoing effort for industry. In this work, we propose a development of a zeolite-based separation process to obtain carbon dioxide-neutral fuels and chemicals. The process designed is based on gas uptake and release, combining separation efficiency with low separation costs. Calculation of separation behavior has been done for mixtures generated by plasmolysis of CO2. Carbon dioxide dissociation into CO and O-2 and as a result a mixture of carbon monoxide, oxygen and a residual carbon dioxide is obtained. Therefore, the purification of CO becomes necessary. Here we provide a purification process design based in multicomponent adsorption and separation in commercial available zeolites. The process identifies NaX and NaY as the most suitable zeolites for separation in a wide range of operating conditions.

Synthesis and characterization of long-side-chain type quaternary ammonium-functionalized poly (ether ether ketone) anion exchange membranes

A series of quaternary ammonium salt poly(ether ether ketone) AEMs containing long ether substituents are successfully prepared, and their chemical structure is confirmed by H-1 NMR and FT-IR. The distinct microphase separation morphology of AEMs is observed by TEM. As the content of methylhydroquinone increases, the ion conductivity of AEMs gradually increases. When the content of methylhydroquinone increases to 80%, the hydroxide conductivity of PEEK-DABDA-80 membrane reaches 0.052 S/cm at 80 degrees C. Meanwhile, it exhibits excellent mechanical properties and anti-swelling ability, with tensile strength of 25 MPa, elongation at break of 8.12% and swelling ratio is only 17.4% at 80 degrees C. And AEMs also display the better thermal stability. After soaked in 1 M NaOH at 60 degrees C for 30 days, PEEK-DABDA-80 membrane shows acceptable ion conductivity of 0.021 S/cm at 60 degrees C. In view of these properties, PEEK-DABDA-x AEMs may display potential application as alkaline AEMs. (c) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.

Highly efficient capture of uranium from seawater by layered double hydroxide composite with benzamidoxime

Through swelling/restoration reaction, benzamidoxime (BAO) is introduced into MgAl-LDHinterlayers to assemble a new composite of MgAl-BAO-LDH (abbr. BAO-LDH). Wet samples of the BAO-LDH obtained by washing with diverse solvents are present in colloidal state, which facilitates the fabrication of thin film adsorbents convenient for actual application. After drying, the assembled sample exhibits floral morphology composed of thin nanosheets, much different from hexagonal morphology of NO3- intercalated MgAl-LDH precursor (NO3-LDH), demonstrating a phenomenon rarely found in swelling/restoration. The BAO-LDH depicts an extremely large maximum sorption capacity (q(m)(U)) of 327 mg.g(-1) and ultra-high selectivity for U. At low U concentrations (5-10 ppm), nearly complete capture (similar to 100%) is achieved in a wide pH range of 3-11, while at high U concentrations (110 ppm), quite high U removals (>= 93.0%) are obtained at pH = 6-8, meaning perfect suitability for trapping U from seawater. For natural seawater containing trace amounts of U (3.93 ppb) coexisting with high concentration of competitive ions, the BAO-LDH displays significantly high U removal (87%). Complexation between interlayer BAO (N and O as ligands) with UO22+ and synergistic interactions of LDH layer hydroxyls with UO22+ contribute to the highly effective uraniumcapture. All results demonstrate the BAO-LDH is a promising adsorbent applied in seawater uranium extraction and nuclear wastewater disposal. (C) 2020 Elsevier B.V. All rights reserved.

Living cationic polymerization of vinyl ethers initiated by electrophilic selenium reagents under ambient conditions

We present a living cationic polymerization of vinyl ethers utilizing electrophilic selenium reagents as initiators and pentacarbonylbromomanganese (Mn(CO)(5)Br) as the catalyst. The polymerization could be carried out under ambient conditions, i.e. no strict purification of reagents, non-inert atmosphere and room temperature. Poly(vinyl ether)s were obtained with controlled molecular weights while maintaining narrow molecular weight distributions (D < 1.2). In this way, different selenium-containing structures could be introduced into chain ends of polymers by using suitable electrophilic selenium reagents. Poly(styrene) prepared by atom transfer radical polymerization (ATRP) followed by brominated selenization was further utilized as a macro-initiator to form the corresponding poly(styrene)-b-poly(isobutyl vinyl ether) copolymers, which offered a new avenue for mechanism transformation polymerization.

Extraction, Evaluation and Structure Elucidation of Bioactive Metabolites of Lactobacillus helveticus CNRZ 32

There is no previous work that utilizes the multi-solvent extraction and structure elucidation of Lactobacillus helveticus cell-free supernatant (CFS). In this study, the CFS of Lb. helveticus CNRZ 32 was extracted by ethyl acetate, diethyl ether, dichloromethane, and n-hexane solvents. The extracts of considerable antimicrobial activities were characterized through GC/MS clarify metabolic profiles, TLC for compounds separation, and bio-autography to determine the number and R-f of effective compounds. Ethyl acetate extract possessed the strongest effect on all tested pathogens with inhibition diameter reached 38 mm in the case of Staphylococcus sciuri, while Diethyl ether and Dichloromethane extracts came secondly. The extract of Ethyl acetate mainly included butyl lactate with area % (59.45), while 9,12-Octadecadienoic acid (Z,Z)-, methyl ester and different health beneficial compounds were identified in both Diethyl ether and Dichloromethane extracts. Due to the strong synergism among Chitosan Nanoparticles and different extracts, the MIC values were lowered by about 20 – 50%.

Carbon dioxide reduction to synthetic fuel on zirconia supported copper-based catalysts and gibbs free energy minimization: Methanol and dimethyl ether synthesis

Thermodynamic equilibria of carbon dioxide recycling via CO2 hydrogenation were predicted by minimization of Gibbs free energy at given conditions, where all existing components were in the gaseous state, for comparison with experimental results obtained with zirconia supported copper-based catalysts. Carbon dioxide hydrogenated to synthetic fuel, i.e. methanol, was investigated at 10 bar and 150-400 degrees C. The CuZnZrO2 catalyst was highly selective towards methanol at low temperatures (up to 99% selectivity), offering the highest yield of 12.6 g CH3OH kg-catalyst(-1) h(-1). However, carbon monoxide was the product with higher selectivity at temperatures above > 210 degrees C. Physically mixing CuZnZrO2 with potassium-modified HZSM5 zeolite increased the CO2 conversion. The synergetic effect between potassium-modified HZSM5 zeolite improved the production of methanol which can be subsequently transformed into dimethyl ether. The bi-functional catalyst allowed the synthesis of valuable products at 50.3 g kg-catalyst(-1) h(-1) (CH3OH, dimethyl ether, and hydrocarbon), while mixing pure HZSM5 with CuZnZrO2 was inherently selective towards hydrocarbons (up to 80%) and allowed the synthesis of valuable products at 14.6 g kg-catalyst(-1) h(-1).

Protective effects of dietary synbiotic supplementation on meat quality and oxidative status in broilers under heat stress

This study evaluated protective effects of synbiotic on meat quality and oxidative status of breast muscle in heat-stressed broilers. Twenty 2-day-old broilers were allocated in a 2×2 factorial design, and the main factors consisted of synbiotic level (0 (basal diet) or 1.5 g/kg synbiotic) and temperature (thermoneutral or high temperature), resulting in 4 treatments. From 22 to 42 days, chickens were raised at thermoneutral temperature (22 degrees C) or subjected to cyclic high temperature (heat stress, HS) by keeping them at 32-33 degrees C for 8 h and 22 degrees C for rest 16 h daily. Cyclic HS decreased relative weight, redness (45 min), and pH values (45 min and 24 h) but increased contents of moisture and ether extract, lightness (45 min and 24 h), drip loss (24 h and 48 h), and cooking loss in breast muscle of broilers compared with those under thermoneutral temperature. It also increased malondialdehyde content and mRNA abundances of heat shock protein 70 (HSP70) and HSP90 but decreased glutathione (GSH) concentration and activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), as well as mRNA abundances of nuclear factor (erythroid 2)-like 2 (Nrf2), NAD(P)H quinone dehydrogenase 1 (NQO1), GSH-Px, and copper and zinc superoxide dismutase in breast muscle in broilers. Dietary synbiotic supplementation was effective in increasing weight and reducing lightness (45 min), drip loss (24 h and 48 h) and cooking loss of breast muscle in heat-stressed broilers compared with those fed the basal diet. It also reduced malondialdehyde content and HSP70 mRNA abundance and increased GSH-Px activity, GSH content, and mRNA abundances of Nrf2, NQO1 and GSH-Px in breast muscle of heat-stressed broilers. These results suggested that synbiotic supplementation at a level of 1.5 g/kg could ameliorate compromised meat quality and oxidative status in broilers under cyclic HS.

Influence of surface-modified glass fibers on interfacial properties of GF/PEEK composites using molecular dynamics

In this paper, molecular dynamics (MD) simulations are carried out to explore the influence of surface modification of glass fiber on interfacial binding energy and failure behavior of GF/PEEK composites. The silane coupling agent and sulfonated PEEK (SPEEK) are employed to modify the surface of glass fibers (GF), and the results reveal that the SPEEK can be employed as an adhesive sizing agent to improve the interfacial bonding strength of GF/PEEK composites. In addition, the synergistic mechanism of non-bonding and mechanical interlocking is investigated by using MD simulations. The interface shear simulation results demonstrate that the interfacial shear strength of composite increased and more resin molecules are found on the surface after SPEEK is incorporated into the GF surface. Moreover, compared with surface-untreated short GF-reinforced PEEK composite, the experimental results demonstrate that the tensile and bending strength of SGF/PEEK composite are improved after interface modification with SPEEK by 21.4% and 30.2%, respectively. The current study presents the utilization of MD simulation for interface design to enhance the mechanical properties of fiber reinforced PEEK composites.
