An efficient method to prepare aryl acetates by the carbonylation of aryl methyl ethers or phenols

Synthesis of valuable chemicals from lignin based compounds is critical for the application of biomass. Here, we develop a method of preparing aryl acetates by the carbonylation of aryl methyl ethers or phenols under low CO pressure. Good to excellent yields of aryl acetates were obtained using different substrates, and a possible reaction mechanism was proposed by conducting a series of control experiments. This method may provide a potential way for the utilization of lignin.

Transcriptome profiling of Pseudomonas aeruginosa YH reveals mechanisms of 2, 2 ‘, 4, 4 ‘-tetrabrominated diphenyl ether tolerance and biotransformation

Aerobic degradation of 2, 2 ‘, 4, 4 ‘-tetrabrominated diphenyl ether (BDE-47) by Pseudomonas aeruginosa YH (P. aeruginosa YH) were investigated in this study. BDE-47 degradation was mainly through the biological action of intracellular enzymes, and the metabolites included debrominated metabolites (BDE-28 and BDE-7), hydroxylated metabolites (6-OH-BDE-47, 5-OH-BDE-47, 2 ‘-OH-BDE-28 and 4 ‘-OH-BDE-17), and brominated phenols (2,4-DBP and 4-BP). P. aeruginosa YH also exhibited exceptional ability to degrade intermediates, and the degradation rates of 50 mu g/L BDE-28, BDE-7, and 2,4-DBP were 68.4%, 82.3% and 92.7% on the 5th day, separately. Transcriptome sequencing revealed that 991 genes were up-regulated, and 923 genes were down regulated in P. aeruginosa YH after exposure to 0.5 mg/L BDE-47 (FDR <= 0.001, vertical bar log(2)Ratio vertical bar >= 1). The differentially expressed genes were related to transport, metabolism and stress response. Harf inhibitory concentration (IC50) of BDE-47 decreased from 167.5 mg/L to 68.4 mg/L when multidrug efflux pump was inactivated by 20 mg/L andrographolide, indicating that it helped the bacterial tolerance against BDE-47. Moreover, efflux pump inhibition would accelerate the adsorption of BDE-47. The adsorption rate obtained equilibrium at approximately 70% in 2 days, while 5 days in the control group. Degradation efficiency of 2 mg/L BDE-47 decreased from 26.8% to 13.9% when multidrug efflux was suppressed.

Concentrations and source identification of PAHs, alkyl-PAHs and other organic contaminants in sediments from a contaminated harbor in the Laurentian Great Lakes

As a result of historical industrial activity, the sediments in the inner harbor of Owen Sound Bay in the northeastern part of Lake Huron in Ontario, Canada are contaminated with organic compounds. The present study showed that the concentrations of Sigma PAH(16-EPA) in all sediments in the inner harbor were above the sediment quality guidelines for the province of Ontario, Canada, with mean. Sigma PAH(16-EPA) concentrations at the most contaminated site of 46,000 mu g/kg dry weight. The concentrations of polychlorinated biphenyls, brominated diphenyl ethers, and organochlorine compounds were all below sediment quality guidelines. The patterns of PAH and alkyl-PAH compounds in sediment cores indicated that contamination is from mixed sources, with a strong indication of pyrogenic contamination from industries that used to operate in the area, including a coal gasification plant. Other areas of the bay are impacted by petrogenic contamination, potentially from spills of fuel. The even distribution of PAH and alkyl-PAH compounds throughout core profiles at depths up to 25 cm indicates that this is a dynamic system and contaminated sediments are not being covered by deposition of less contaminated sediments. This study illustrates the value of determining the patterns of both PAH and alkyl-PAH compounds in sediments for regulatory purposes and also for forensic source tracking. (C) 2020 Elsevier Ltd.

Characterization of Olfactory Receptor Repertoires in the Endangered Snow Leopard Based on the Chromosome-Level Genome

Olfaction is a complicated process that begins with the specific binding of volatile odorant molecules to dedicated olfactory receptors (ORs) in the olfactory epithelium and plays a pivotal role in the survival of mammals. The OR subgenome of the snow leopard has remained largely unexplored, and thus, investigation of the OR system would shed light on the evolutionary dynamics of the snow leopard OR repertoires and genetic evidence for environmental adaptation. In this study, we conducted genome-wide identification and characterization of OR genes in the snow leopard and compared them to all other Panthera species. A total of 213, 294, 624, 305, and 253 functional OR genes were identified in the snow leopard, lion, jaguar, leopard, and tiger, respectively. The phylogenetic relationships of functional Panthera OR genes were illustrated, which comprised 69 families and 350 subfamilies distributed in two classes (Class I and Class II). Comparative analysis of the five Panthera species indicated 115 shared and 5 snow leopard-specific clusters. The potential odorant specificity of certain snow leopard OR genes was identified by similarities to human protein sequences and we identified odorants such as eugenol methyl ether that had the most OR genes. Since our references for odorants were from human studies, possible odorants from snow leopard-specific OR genes need further investigation. The lowest number of OR genes for the snow leopard among Panthera species possibly revealed the association between OR gene family contraction and high-altitude adaptation, which needed further and deeper investigation. This systematic study of OR genes in the snow leopard will provide a solid foundation for further study of olfactory function and variation in the snow leopard.

Extractives of Stemwood and Sawmill Residues of Scots Pine (Pinus sylvestris L.) for Biorefining in Four Climatic Regions in Finland-Phenolic and Resin Acid Compounds

This study aimed to identify and quantify phenolic and resin acid extractive compounds in Scots pine stemwood and sawmill residues in four climatic regions of Finland to evaluate their most optimal sources for bio-based chemical biorefining and bioenergy products. The sample consisted of 140 trees from 28 stands, and sawdust lots from 11 log stands. NMR for the overall extractive analysis and HPLC for the quantitative estimation of phenolic and resin acid compounds were employed. Correlation analysis, multivariate factor analysis, principle component analysis and multiple linear regression modelling were applied for statistical analysis. HPLC identified 12 extractive compounds and NMR five more resin acids. Pinosylvin (PS), pinosylvin monomethyl ether (PSMME), and partly neolignans/lignans occurred in the largest concentrations. Wood type caused the most variation, heartwood having larger concentrations than sapwood (sawdust between them). Regional differences in the concentrations were smaller, but factor analysis distinguished the northern and the southern regions into their own groups. The results indicated higher concentrations of PS, PSMME, and vanillic acid in southern regions and those of, e.g., PSMME glycoside, lignan 2, and neolignan 1 in northern regions. The rather low concentrations of extractives in stemwood and sawdust imply value-added products, efficient sorting and/or large raw material volumes.

Epoxidized soybean oil modified using fatty acids as tougheners for thermosetting epoxy resins: Part 2-Effect of curing agent and epoxy molecular weight

A series of bio-rubber (BR) tougheners for thermosetting epoxy resins was prepared by grafting renewable fatty acids with different chain lengths onto epoxidized soybean oil at varying molar ratios. BR-toughened samples were prepared by blending BRs with diglycidyl ether of bisphenol A resins, Epon 828 and Epon 1001F, at different weight fractions and stoichiometrically cured using an amine curing agent, 4, 4 ‘-methylene biscyclohexanamine (PACM). Fracture toughness properties of the unmodified and BR toughened polymer samples-including critical strain energy release rate (G(Ic)), and critical stress intensity factor (K-Ic)-were measured to investigate the toughening effect of prepared BRs. It was found that the degree of phase separation and toughening were more controllable relative to similar polymers cured using the aromatic curing agent Epikure W, and the use of higher molecular epoxy resins produces a synergistic effect increasing the toughness much more than similar polymers made with lower molecular weight epoxy resins. Average BR domain sizes ranging from 200 to 900 nm were observed, and formulations with G(Ic), values K-Ic as high as 1.0 kJ/m(2) and 1.4 MPa m(1/2) were attained respectively for epoxy systems with T-g greater than 130 degrees C.

Synthesis, structure and property of two D-f heteronuclear Eu-TM (TM = Zn and Cd) complexes with open-chain ether Schiff base ligand

Two heteronuclear Zn-Eu and Cd-Eu complexes with open-chain ether Schiff base ligand (bis(5-bromine-3-methoxysalicylidene)-3-oxapentane-1,5-diamine (H2L) and isonicotinate (IN), with composition [ Zn2EuL2(OAc)(IN)](NO3)center dot(CH2Cl2) (1) and ([CdEuL(IN)(OAc)(NO3)(CH3OH)]center dot 3(CH2Cl2)}(n) (2), have been synthesized and characterized. The structure analysis reveals that the Zn-Eu complex is heterotrinuclear cluster and lanthanide ion acts as a joint bridging of two Zn-L coordination units, whereas the Cd-Eu complex is infinite 1D zigzag coordination polymer formed by Cd-Eu-L secondary units through bridging of isonicotinate. Fluorescence properties of complexes 1-2 in the solid state and DMF solution at room temperature were studied. It has been found that the emission spectra of complexes 1-2 do not exhibit corresponding Eu-III ion characteristic emission bands and the fluorescence properties of complexes 1-2 are different due to the introduction of different transition metal ions. Antioxidant properties of the ligand and complexes 1-2 were also studied, the results showed that the ligand and complexes 1-2 display high scavenging activity against hydroxyl (OH center dot) and superoxide (O-2(-)center dot) radicals, and the order of the activity is complex 2 > complex 1 > H2L. Therefore, the structures and properties of D-f heteronuclear complexes can be adjusted by selecting different transition metal ions such as Zn-II and Cd-II ions. (C) 2020 Elsevier B.V.

Structure and properties of sulfonated poly(arylene ether)s with densely sulfonated segments containing mono-, di- and tri-tetraphenylmethane as proton exchange membrane

Multiple factors affecting the sulfonated poly (arylene ether) proton exchange membrane materials are worthy of being systematically explored. In order to investigate the variation of membrane materials based on ion exchange capacity (IEC) and hydrophilic segment length, three series of dense sulfonated poly (arylene ether)s (mt-SPAE-y, dt-SPAE-y and tt-SPAE-y) containing mono-, di- and tri-sulfonated tetraphenylmethane structural units were synthesized. Each series contains three sulfonated copolymers with different IEC values. Small angle X-ray scattering and transmission electron microscopy results show that increasing the IEC value is conducive to the aggregation of hydrophilic ion clusters, while the growth of hydrophilic segment length helps to the formation of larger hydrophilic ion clusters. Both variations favor the construction of connected hydrophilic ion channels. Based on the highest IEC value and the longest hydrophilic segment length, the tt-SPAE-1.94 membrane forms a connected hydrophilic channel that allows it to exhibit the highest proton conductivity and lowest activation energy of the proton conductivity. Good thermal properties, mechanical properties and oxidation resistance lay the foundation for the durability of the membrane in fuel cells. Finally, the tt-SPAE-1.94 membrane was used for membrane electrode assembly at 80 degrees C and 95% relative humidity, exhibiting a power density of 418 mW cm(-2) in H-2/air fuel cell test. In summary, both the increase in the IEC value and the length of the hydrophilic segment contribute to the formation of good hydrophilic-hydrophobic phase morphology, thereby enhancing the macroscopic properties of the sulfonated poly (arylene ether) proton exchange membrane material. The results prove that these three series of membranes show outstanding prospects in actual fuel cell operation and have considerable research value.

A Giese reaction for electron-rich alkenes

A general method for the hydroalkylation of electron-rich terminal and non-terminal alkenes such as enol esters, alkenyl sulfides, enol ethers, silyl enol ethers, enamides and enecarbamates has been developed. The reactions are carried out at room temperature under air initiation in the presence of triethylborane acting as a chain transfer reagent and 4-tert-butylcatechol (TBC) as a source of hydrogen atom. The efficacy of the reaction is best explained by very favorable polar effects supporting the chain process and minimizing undesired polar reactions. The stereoselective hydroalkylation of chiral N-(alk-1-en-1-yl)oxazolidin-2-ones takes place with good to excellent diastereocontrol.

Ignition delay times of iso-butane activated by DME under various equivalence ratios in the shock tube

The ignition delay time of the high cetane number dimethyl ether (DME), high octane number i-butane, and their binary blends were investigated in a shock tube over the temperature range of 1091-1797 K, pressures of 2-10 atm, and equivalence ratios of 0.5-2.0. The LLNL iso-Octane Model and the DME sub-set of the Aramco3.0 Model were assembled together to reproduce the ignition delay behavior of the binary blends. Chemical kinetic analyses were conducted to understand the interplay between DME and i-butane at high temperatures. The ignition delay of DME and i-butane show the opposite equivalence ratio dependence under the current conditions. The promoting effect of DME addition on the ignition delay of i-butane becomes more significant as the equivalence ratio increases. The research result shows that there is no significant fuel to fuel interactions between DME and i-butane in the present conditions. The high reactivity of DME and its rapid accumulation of the free radicals lead to the promoted auto-ignition of i-butane.
