Initiation of Radical-Chain Aerobic Oxidation of Cumene by Potassium Permanganate and N-Hydroxysuccinimide
摘要
The kinetics of the liquid-phase oxidation of cumene (RH) with molecular oxygen in the presence of KMnO4 and N-hydroxysuccinimide (NHSI) is studied. An increase in the reaction rate when adding acetic acid is established. An synergistic effect of KMnO4 and NHSI in aerobic oxidation of RH is found. This can be associated with the formation of C-centered (R⦁) and O-centered (SINO⦁) radicals that participate in the chain initiation stage and the catalysis of the chain propagation stage by the SINO⦁ radical.
