摘要

研究了在 N-羟基邻苯二甲酰亚胺存在下，分子氧将对叔丁基积苯氧化成过氧化氢的动力学。通过分析过氧化氢和副产品的形成规律，构建了该过程的数学模型，该模型充分描述了反应中主要成分的浓度随时间的变化。N- 羟基邻苯二甲酰亚胺的主要作用是将过氧化物自由基转化为相应的氢过氧化物，从而通过降低二次链终止率来减少副产品的产量。此外，形成的 N-羟基邻苯二甲酰亚胺自由基会提高碳氢化合物的氧化速率。因此，在碳氢化合物氧化过程中使用 N-羟基邻苯二甲酰亚胺可提高过氧化氢的形成速率和选择性。

Kinetic Laws of Oxidation of para-tert-Butylcumene in the Presence of N-Hydroxyphthalimide

The kinetics of the oxidation of para-tert-butylcumene to hydroperoxide by molecular oxygen in the presence of N-hydroxyphthalimide was studied. By analyzing the laws of the formation of hydroperoxide and byproducts, a mathematical model of the process was constructed, which adequately describes the changes in the concentrations of the main components of the reaction over time. The main role of N-hydroxyphthalimide is to convert peroxide radicals into the corresponding hydroperoxides, thereby reducing the yield of byproducts by decreasing the quadratic chain termination rate. Moreover, the formed N-hydroxyphthalimide radicals increase the rate of hydrocarbon oxidation. Thus, the use of N-hydroxyphthalimide in hydrocarbon oxidation processes results in an increase in the rate and selectivity of hydroperoxide formation.
