摘要

研究了在 KMnO4 和 N-hydroxysuccinimide (NHSI) 的存在下，分子氧对积雪烯 (RH) 的液相氧化动力学。结果表明，加入醋酸后反应速率会增加。研究发现 KMnO4 和 NHSI 对 RH 的有氧氧化具有协同作用。这可能与 C-centered (R⦁) 和 O-centered (SINO⦁) 自由基的形成有关，C-centered 自由基参与了链的起始阶段，而 SINO⦁ 自由基则催化了链的扩展阶段。

Initiation of Radical-Chain Aerobic Oxidation of Cumene by Potassium Permanganate and N-Hydroxysuccinimide

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.
