PECULIARITIES OF CYCLOHEXANE OXIDATION MECHANISM BY MEANS OF “GREEN OXIDIZER” HYDROGEN PEROXIDE ON per-FTPhPFe3+OH/Al2O3

Abstract

In the process of gas-phase coherently synchronized oxidation of cyclohexane by hydrogen peroxide in the presence of a heterogeneous biomimetic catalyst per-FTPhPFe 3+ OH/Al 2 O 3 , the reaction products were cyclohexanol, cyclohexanone and cyclohexene. An experimental study aimed at clarifying the routes of cyclohexane conversion into cyclohexanone and cyclohexene made it possible to determine mechanisms for producing cyclohexanone and cyclohexene. The study went to show that the conversion of cyclohexane into cyclohexanone takes no place through the formation of cyclohexanol, and the formation of cyclohexene occurs by dehydration of cyclohexanol. The mechanism of cyclohexanone formation is manifest through the formation of an intermediate biomimetic -substrate complex Imt-O-C 6 H 11 which is formed as a result of intermediate (ImtOOH) interaction with cyclohexane.
