- Аннотация: The article investigates the kinetics of the oxidation reaction of dimethyl cumene to hydroperoxides with molecular oxygen in the presence of N-hydroxyphthalimide.. In order to obtain information on the kinetic laws related to the process of dimethyl cumene oxidation in the presence of N-hydroxyphthalimide, a series of experiments was conducted. The experimental data related to the kinetics of hydroperoxides and non-reaction products formation provided the mathematical model that adequately describes the change of all components of the reaction at the time. It was established that the role of N-hydroxyphthalimide as the initiator of the process is determined by the fact that its interaction with oxygen results in the stationary concentration of N-phthalimide radicals, which initiate oxidation process in their interaction with hydrocarbon. The experimentally tested high-selective method used for the synthesis of hydroperoxides by liquid-phase catalytic dimethyl cumene oxidation can become the basis of a single universal method for producing xylenols that meets the latest environmental and economic requirements. The suggested mathematical model of the dimethyl cumene oxidation to hydroperoxides in the presence of NHPI is original and may be of interest for calculating the kinetics of similar reactions involving other alkylaromatic hydrocarbons.
