A STUDY OF THE KINETICS AND MECHANISM OF LIQUID-PHASE OXIDATION OF ETHYL¬BEN¬-ZENE IN THE PRESENCE OF COBALT-BASED POLYMER CATALYSTS WITH ACTIVE CENTERS TUNED TO HYDROCARBON SUBSTRATES

The focus of the present study is liquid-phase oxidation alkylaromatic hydrocarbons, particularly that ethylbenzene, in presence cobalt-based polymer complexes tuned to ethylbenzene and obtained based on cobalt salts a copolymer diethyl ether phenylphosphonic acid with acrylic acid. reaction was carried out without solvent at atmospheric pressure 900C temperature glass temperature-controlled equipped reactor. Oxidation by bubbling gaseous oxygen through mass. It shown tuning leads significant increase rate formation products. heterogeneous-homogeneous mechanism process, radicals surface their subsequent release into liquid volume products radical-chain have been established. We also studied specificity complexʹs ability tune α-phenylethyl hydroperoxide way identical its ethylbenzene. As result our study, hydroperoxide, methylphenylcarbinol acetophenone were
