Study on oxidation mechanism of cumene based on GC-MS analysis

Based on the gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS) spectra, the analysis of the products of the catalytic oxidation and its mechanism can be elucidated. Here, the analysis of the aerobic oxidation products of cumene catalyzed by the polymer ferric complex through GC-MS has been performed. The main products are 2-phenyl-2-propanol (PP), 2-phenyl-2-iso-propyl hydroperoxide. From the analysis, the radical reaction mechanism was presumed. The relationship between the selectivity of cumene hydroperoxide and PP has been studied. (C) 2000 Elsevier Science B.V. All rights reserved.
