Study of the kinetic regularities of the process of liquid phase oxidation of sec-butylbenzene in the presence of N-hydroxyphthalimide

Abstract

The kinetic patterns of liquid-phase aerobic oxidation of sec-butylbenzene to its tertiary hydroperoxide in the presence of N-hydroxyphthalimide as a catalyst have been studied. The influence of temperature, reaction duration and catalyst content on the rate of sec-butylbenzene oxidation was studied. Based on the experimental data obtained, a kinetic (mathematical) model of the process under study was compiled, which adequately describes the change in the concentration of the main components during the reaction. The numerical values of the rate constants of the main stages of the process are calculated. It was revealed that the oxidation of sec-butylbenzene in the presence of N-hydroxyphthamilide allows you to intensify the oxidation process of this hydrocarbon while maintaining high rates and selectivity of the formation of its hydroperoxide.
