Macrokinetic Coherence Of Gas-Phase Ethylene Monooxidation Reaction By Hydrogen Peroxide

The gas-phase monooxidation of ethylene by hydrogen peroxide on a biomimetic heterogeneous catalyst, perfluorinated iron (III) tetraphenylporphyrin, deposited on alumina (per-FTPhPFe3+OH/Al2O3)was studied under comparatively mild conditions. The biomimetic oxidation of ethylene with hydrogen peroxide was shown to be coherently synchronized with the decomposition of H2O2. Depending on reaction medium conditions, one of two desired products was formed, either ethanol or acetaldehyde. The probable mechanism of ethylene transformation was studied. A kinetic model that fits the experimental data is studied on the basis of the most probable mech-anism of ethylene oxidation by hydrogen peroxide over a biomimetic catalyst (per-FTPhPFe3+OH/Al2O3). Effective rate constants for the catalase and monooxygenase reactions and their effective activation energies are found
