Sentence examples for methyl radicals which from inspiring English sources
Except for the coupling of methyl radicals, which occurs in the gas phase, surface reactions are responsible for most of the methane conversion.
The adsorbed NO2 would activate methane molecules and yield hydrogen and methyl radicals, which could in turn react with NO2 to generate nitromethane intermediates.
The reaction of methane production can involve methyl radicals, which come from propane combustion, as follows: CH 3 + C 6 H 5 cy − > C 6 H 5 I (34).
Additionally during the metabolism of MMH, N-methyl-N-formylhydrazine is produced; this then undergoes cytochrome p450 regulated oxidative metabolism which via reactive nitrosamide intermediates leads to formation of methyl radicals which lead to liver necrosis.
This assumption is valid if we take into consideration the reactive nature of the H radical relative to the methyl radical which may yield 3-methylpyridine (a minor product) [20, 29].
The rate-determining step is that of the metal-methyl dissociation leading to the formation of the methyl radical which determines a high activation energy of methane dehydrodimerization on oxide catalysts.
The sensitivity analysis points out the main reactional pathways involved in the thermal degradation of MEK in flame conditions and reveals the important production of methyl and ethyl radicals which lead, by recombination processes, to the formation of the oxygenated intermediate compounds.
Computational and experimental results support the hypothesis that the dominant pathway to C6H6 formation begins with the oxygenates decomposing into methyl radical (CH3), which combines with C2 species to form propargyl (C3H3), which reacts with itself to form C6H6.
The phenylalanine has been synthetically modified to carry a methyl group, which provides the majority of the sweetness.
The selectivity of the active catalyst is mainly due to very high rates of methyl radical production which couple in the gas phase.
In particular, H-atom abstraction from isobutene results in the formation of the 2-methyl allyl radical, which undergoes a β-scission reaction to form allene plus methyl.
