Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. HPLC of Formula: C9H8O. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

This study combines the results of experimental measurements and theoretical computations to investigate the initial steps in the oxidation of dibenzo-. p-dioxin (DD). The aim is to discover new pathways leading to the formation of toxic species in combustion systems, as well as compounds that may act as precursors for polychlorinated dibenzo-. p-dioxins and polychlorinated dibenzofurans (PCDD/F). The experiments were performed in a tubular reactor equipped with sampling systems for condensable and gaseous products. The reaction conditions were characterised by a residence time of 5. s and a fuel equivalence ratio of 0.12. We investigated the effect of temperature (400-800C) on the type and the yield of the oxidative products, trapped in a cartridge, and gases collected in tedlar bags for subsequent FTIR analyses. The analyses of VOC, performed on a high resolution gas chromatograph-triple quadrupole mass spectrometer (HRGC-QQQMS), identified 2-methylbenzofuran and 3-hydro-2-methylenebenzofuran as the initial products. This has been confirmed by injection of authentic standards and the application of collision induced dissociation (CID) that fragmented the isolated parent ions into specific product ions affording the identification of parent species. The oxidative decomposition of DD initiated at around 450C, with the evolution of VOC peaking at between 650 and 700C. In excess of 750C, all VOC were completely oxidised. The potential energy surface (PES), based on the density functional theory (DFT) of B3LYP, mapped the initial steps involved in the oxidation of DD, and yielded a detailed reaction scheme for the onset of oxidation of DD that results in the formation of 2-methylbenzofuran and 3-hydro-2-methylenebenzofuran. Initial oxidation of DD is most likely to commence via addition of the singlet oxygen molecule and the subsequent facile formation of the propagating OH radical.

A trifluoroacetic acid promoted step-economical one-pot approach to the synthesis of furo-fused quinoxalines/pyrazines by the reaction of 2,3-dichloroquinoxalines/pyrazines with alkynes is described. The reaction involves a selective in-situ Sonogashira coupling step and a hydroxylation followed by a metal-free 5-endo-dig cyclization. Preliminary experiments show that trifluoroacetic acid acts as a source of oxygen for the oxyarylation step, and isotopic labeling studies support the proposal that the mechanistic pathway involves activation of the alkyne by the acidic medium. Various kinds of substituents are tolerated, which should prove valuable for structural and biological investigations.

ZSM-5 zeolite is an efficient catalyst for both biomass deoxygenation and polyolefins cracking in pyrolysis process. In this study, wood-plastic composite (WPC), composed mainly of woody materials and thermoplastic polymers, was pyrolyzed using Py-GC/MS over phosphorus-modified HZSM-5 (P-HZSM-5) with varying P loadings (from 0 to 10 wt.%). The catalysts were prepared by wet impregnation method and characterized by XRF, XRD and NH3-TPD. The effects of pyrolysis temperature, time, heating rate, catalyst to WPC ratio and P loadings on the hydrocarbon distribution of WPC pyrolysis were studied. Pyrolysis conditions have significant effects on hydrocarbon distribution. Parent HZSM-5 facilitated aromatics formation, while P-HZSM-5 favored the formation of light aliphatic hydrocarbons (C4-C12). The yields of C4-C12 increased first with rising pyrolysis temperature from 450 to 550 C, then decreased over 550 C. Similarly, C4-C12 yields increased during the pyrolysis time from 15 to 30 s and decreased with the further prolonged time. A low heating rate (0.002 C/ms) favored the formation of light aliphatic hydrocarbons, while high heating rates (>0.2 C/ms) favored the formation of aromatics. Increasing catalyst to WPC ratio augmented aromatic selectivity. Hydrocarbon distribution strongly depended on the catalyst’s acidity, adjusted by varying P loading in P-HZSM-5. The highest yield of C4-C12 was obtained while using P-HZSM-5 with P loading of 3.5 wt.%.

Humic substances (HS) isolated from swamp water, surface soil, peat and brown coal were characterized using elemental composition, solid state 13C CP/MAS NMR and Py-GC/MS analysis. A substantial amount of information with regard to the source, maturity, depositional environment and degree of degradation of humic substances was obtained. The elemental composition, atomic ratio, 13C NMR spectra and Py-GC/MS results indicated that vascular plant matter is the main contributor to humic substances. Humic substances from swamp water and from soil in the surrounding area of the swamp were found to be identical, suggesting that the swamp humic substances are derived from surrounding soils. Humic substances from brown coal were characterized by a higher degree of humification, including loss of polysaccharides, degradation in lignin content and increase in aromaticity. Compared with humic substances from brown coal, the humic substances from peat showed a lower degree of humification and were considerably more aliphatic in nature. (C) 2000 Elsevier Science Ltd.
