WebBoth electron paramagnetic resonance (EPR) and classic quenching tests were carried out to investigate the mechanism of radical generation and evolution in phenol oxidation. Different from Co- and Mn-based catalysts in generation of sulfate radicals, Fe0/Fe3C@CS selectively induced hydroxyl radicals for phenol degradation. 展开 WebThe gas-phase oxidation mechanism of phenol initiated by OH radical was investigated using DFT and ab initio calculations. The initiation of the reaction is dominated by OH …

Web17. jan 2024 · The oxidative dearomatization commences with the ligand exchange between IBX and phenol, yielding a phenolate complex, followed by the first redox process, which reduces iodine(V) to iodine(III). Both the processes (the ligand exchange and the first redox reaction) were found to be mediated by a less stable isomer of iodine( V ) species. Web26. júl 2024 · The main oxidation product is phenol (up to 77.3 wt %). Small amounts of dihydric phenols (mainly hydroquinone) were found. Catechol, o‑hydroxybiphenyl, biphenyl, and other compounds have also been detected.The conversion of benzene per pass of the gas–vapor mixture through the reactor was 0.7 wt % in oxygen or 0.4 wt % in air, which … the nether inn dundee
