Isotope experiments with 18O2, H2 18O, and D2O suggest that 1-phenethyl alcohol is oxidized to acetophenone by a minor reaction involving desaturation ...
WebJan 1, 2024 · Oxidation of ethylbenzene (EB) is one of the promising methods to synthesize AP in liquid and vapor phases reaction using heterogeneous catalysts, which plays a vital role for selective production of AP. WebThe selective conversion of EB into AcPO is attributed to the oxidative radicals generated from the decomposition of PMS molecules via the electron transfer between Co atoms and PMS. Sulfate radicals (SO 4 ˙ −) make a greater contribution than others to activate the C–H bond in EB oxidation.
