The peroxidase activity of the synthesized heterogeneous biomimetic catalysts, PPFe3+OH/Al2O3, TPhPFe3+OH/Al2O3 and per-FTPhPFe3+OH/Al2O3 in the reaction of ethyl alcohol oxidation to acetaldehyde with hydrogen peroxide has been studied, which showed high catalase activity and unique resistance to the action of highly active intermediate reaction products. As a result of studying the kinetic regularities of the selective biomimetic oxidation of ethyl alcohol with hydrogen peroxide, a coherent-synchronized nature of the reaction was established, consisting of two: 1) catalase and 2) peroxidase reactions. The kinetics of coherent-synchronized peroxidase oxidation of ethyl alcohol to acetaldehyde on heterogenized biomimetic catalysts, PPFe3+OH/Al2O3, TPhPFe3+OH/Al2O3 and per-FTPhPFe3+OH/Al2O3 has been studied. Based on the determinant equation, which makes it possible to qualitatively and quantitatively evaluate the coherent nature of synchronously occurring reactions and the reaction coherence ratio, a kinetic model of the process has been compiled. On the basis of the compiled kinetic model, the effective rate constants of the catalase and peroxidase reactions were derived, respectively. The derived kinetic model of the process is characterized by a high adequate description of the experimental data
