This work reports an experimental and kinetic modelling investigation on flow reactor pyrolysis jet-stirred oxidation of o-xylene. The experiments were conducted over 1050–1600 K at 0.04 1.0 atm. Key products related to fuel decomposition such as o-xylyl radical, o-xylylene, benzocyclobutene styrene, well polycyclic aromatic hydrocarbons (PAHs), detected by using synchrotron vacuum ultraviolet ...
We report the detection, for first time in space, of a new non-functionalised hydrocarbon cycle direction TMC-1: o -C 6 H 4 (ortho-benzyne). derive column density this (5.0 ± 1.0) × 10 11 cm −2 . The abundance species is around 30 times lower than that cyclopentadiene and indene. compare benzyne with other pure hydrocarbons, cycles or chains, find it could be formed from neutral-radical reactio...
Binary collisions of ground state carbon atoms, C(3P j), with benzene, C6H6(XA1g), and of phenyl radicals, C6H5(XA1), with methylacetylene, CH3CCH(XA1), were investigated in crossed beam experiments, ab initio calculations, and via RRKM theory to elucidate the underlying mechanisms of elementary reactions relevant to the formation of polycyclic aromatic hydrocarbons (PAHs) in extraterrestrial e...
In order to better understand land application of sewage sludge, the characterization of heavy metals, PCDD/F and PAHs in sewage sludge was investigated from six different wastewater treatment plants (WWTP) in Beijing City, China. It was found that the total concentrations of Zn in Wujiacun (WJC) sewage sludge, and Cd and Hg in sewage sludge generated from all of the six different places are hi...
The aminoalkylindoles (AAIs) are agonists at both the cannabinoid CB1 and CB2 receptors. To determine whether the s-trans or s-cis form of AAIs is their receptor-appropriate conformation, two pairs of rigid AAI analogues were studied. These rigid analogues are naphthylidene-substituted aminoalkylindenes that lack the carbonyl oxygen of the AAIs. Two pairs of (E)- and (Z)-naphthylidene indenes (...
