Kinetic studies of m-diisopropylbenzene oxidation catalyzed by basic ionic liquid[ BMIM]OH

The oxidation reaction kinetics of m-diisopropylbenzene catalyzed by ionic liquid [BMIM]OH was studied in a 2 L-stirring reactor under the condition of reaction temperature（ 80-95） ℃ and air flow rate 300 L·h-1. According to the thermodynamics analysis,the reaction network of the oxidation system was obtained,and the main reaction and side reaction of the reaction system were determined. Based on the reaction mechanism,the kinetic model equation was built by revising the rate equation of the power function. Kinetic parameters of the model equation were estimated based on the kinetic experimental data and the corresponding model tests were carried out. The obtained reaction kinetic models could well describe the oxidation reaction of m-diisopropylbenzene.
