Fast pyrolysis with cheap Ni-based catalysts was evaluated to produce bio-oil from jatropha residues. By Py-GC/MS method with catalyst/jatropha weight ratio of 6.2, Ni/zeolite-based catalysts such as NiMo(O)/Y(14) were found to be promising candidates for total hydrocarbon formations. But, with low catalyst/jatropha ratio of 0.35-0.76, the total hydrocarbon selectivities were NiMo(O)/Y(14)(71.7%) > PtPd/ZSM(38)(68.8%) > Ni2P/Y(14)(65.4%) > NiMo(O)/Beta(27)(63.9%) > NiMo(O)/ZSM(38) (60.1%) > none (36.4%), when the pyrolysis was carried out using a stainless-steel reactor under N2 gas flow. When jatropha residues (50 g) was used with NiMo(O)/Y(14) at 500 C, total liquid yield was as high as 49.9%, including 21.3% of organic liquid. Taking into account higher Aromatic/Aliphatic selectivities, lower acid selectivities at both 600 C and 500 C, Ni-based catalysts such as NiMo(O)/Y(14) were found to be effective and comparable to PtPd/ZSM(38). The acid values of organic liquids obtained at 600 C were 2.74-7.02 mg-KOH kg-1, being much lower than 28.2 mg-KOH kg-1 in the absence of catalyst. The estimated higher heating values (HHV) of the liquid were 32-33 MJ/kg. The NiMo(O)/Y(14), NiMo(O)/ZSM(38) and Ni2P/Y(14) catalysts could be regenerated by calcination at 600 C, followed by subsequent hydrogenation, and the organic liquid product yields remained constant at fresh and regenerated catalysts and total hydrocarbon selectivities were also constant within the experimental error. Thus, under these pyrolysis conditions, Ni-based catalysts seems to be better and cheaper candidates than PtPd systems.

A library of 2,5-disubstituted 1,3,4-oxadiazole derivatives of (E)-2-aryl-5-(3,4,5-trimethoxystyryl)-1,3,4-oxadiazoles 4(a-o) and (E)-2-aryl-5-(2-benzo[d][1,3]dioxol-5-yl)vinyl)-1,3,4-oxadiazoles 5(a-q) were synthesized and evaluated for their in vitro acetylcholinesterase (AChE) inhibitory activity. All the synthesized compounds exhibited moderate to good inhibitory activity toward the AChE enzyme. Among the oxadiazole derivatives examined, compounds 4a, 4g, 5c, and 5m (IC50 values of 24.89, 13.72, 37.65, and 19.63 muM, respectively) were found to be promising inhibitors of AChE.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. SDS of cas: 4265-25-2. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

In this study, sawdust was selected as the raw material for biomass pyrolysis to obtain organic products. The catalyst was modified with two elements (Fe and Zn). Through analysis of the catalytic products, we attempted to identify a pyrolysis catalyst that can improve the yield of aromatic hydrocarbon products. ZSM-5, modified with Fe and Zn, was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and Brunauer?Emmett?Teller (BET) measurements. Tube furnace and flash pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) were used to comprehensively investigate the characteristics of the products of biomass pyrolysis. The highest yield of phenols was obtained using the Fe-modified ZSM-5 catalyst, which was 18.30% higher than the yield obtained by the pure ZSM-5 catalyst. The lowest yield of acid products was obtained by single-metal-supported catalytic pyrolysis with Fe or Zn, which was 50.66% lower than the yield obtained by direct pyrolysis. During the pyrolysis of biomass using metal-modified catalysts, the production of aromatic hydrocarbons was greatly improved. Among them, compared with direct pyrolysis, the Fe-Zn co-modified ZSM-5 catalyst exhibited the weakest promotion of aromatic hydrocarbon formation, but there was still a 68.50% improvement. Although the co-modified catalyst did not show absolute advantages under the conditions used for this experiment, the improvements in the production of aromatics and phenolic products also showed its potential for improving bio-oil products. Under the action of Fe-modified catalysts, the most abundant components in the gas product were CO and CO2, which reached levels as high as 53.45% and 15.34%, respectively, showing strong deoxidation capabilities. Therefore, Fe-modified ZSM-5 catalysts were found to better promote the formation of aromatic hydrocarbon products of biomass pyrolysis.

The cyanation of arylboronic acids by using acetonitrile as the “CN” source has been achieved under a Cu(cat.)/TEMPO system (TEMPO=2,2,6,6-tetramethylpiperidine N-oxide). The broad substrate scope includes a variety of electron-rich and electron-poor arylboronic acids, which react well to give the cyanated products in high to excellent yields. Mechanistic studies reveal that TEMPO-CH2CN, generated in situ, is an active cyanating reagent, and shows high reactivity for the formation of the CN- moiety. Moreover, TEMPO acts as a cheap oxidant to enable the reaction to be catalytic in copper.

Biohydrogen production potential (BHP) depends on several factors like inoculum source, substrate, pH, among many others. Batch assays are the most common strategy to evaluate such parameters, where the comparison is a challenging task due to the different procedures used. The present method introduces the first internationally validated protocol, evaluated by 8 independent laboratories from 5 different countries, to assess the biohydrogen potential. As quality criteria, a coefficient of variation of the cumulative hydrogen production (Hmax) was defined to be <15 %. Two options to run BHP batch tests were proposed; a manual protocol with periodic measurements of biogas production, needing conventional laboratory materials and analytical equipment for biogas characterization; and an automatic protocol, which is run in a device developed for online measurements of low biogas production. The detailed procedures for both protocol options are presented, as well as data validating them. The validation showed acceptable repeatability and reproducibility, measured as intra- and inter-laboratory coefficient of variation, which can be reduced up to 9 %.

Despite the prevalence of head-to-side chain threonine linkages in natural products, their incorporation has been underexplored in synthetic cyclic peptides. Herein we investigate a cyclic peptide scaffold able to undergo an N-O acyl rearrangement. Upon acylation of the amine with diverse carboxylic acids, the resulting cyclic depsipeptides displayed favorable cellular permeability and a conformation similar to the parent peptide. The rearrangement was found to be scaffold and conformation dependent as evidenced by molecular dynamics experiments.

An efficient lipase-catalyzed desymmetrization of prochiral 2,2-disubstituted 1,3-propanediols was developed using 1-ethoxyvinyl 2-furoate 1b, for which the well-known method using vinyl or isopropenyl acetate has had limited success due to low reactivity and easy racemization of the products through acyl group migration. The reagent 1b is highly reactive and converts various prochiral 1,3-diols to the monoesters having a chiral quaternary carbon center with 82-99% ee. These products were stable against racemization under acidic conditions, and their furoyl groups were compatible with oxidative conditions. Prolonging the reaction time led to the kinetic resolution of the monoesters resulting in an increase of their optical purity. The similar desymmetrization of meso cis-1,2-cycloalkanediols gave the monoesters with 82-97% ee without racemization.
