The study of cyclooctene oxidation with molecular oxygen catalyzed by VSi2

Abstract

Abstract:The catalytic effect of VSi 2 on initial stages of the liquid-phase oxidation of cyclooctene by molecular oxygen was studied. The vanadium disilicide influences on the oxidation process in the presence of hydroperoxide. VSi 2 takes part in a radical formation stage by catalysis of hydroperoxide decomposition reaction. The catalyst was investigated before and after reaction using FTIR spectroscopy. From the data obtained, the kinetic model of the catalytic oxidation process was proposed and the equation for the reaction rate was derived. The equation has described all observed dependences of reaction rate on the concentration of reactants and content of catalyst.

The Influence of Metal Carbides on the Oxidation Processes of 1-Octene by Molecular Oxygen and tert-Butyl Hydroperoxide

“…Taking into account the obtained results and based on data of literature [14,15] as well as data of our previous works [16][17][18], we can propose the next model of the radical formation process in the oxidation process of 1-octene by molecular oxygen in the presence of metal carbides and TBHP on the initial stages of the reaction…”

“…The overall scheme of the oxidation process of olefins by molecular oxygen in the presence of catalysts and TBHP on the initial stages of the reaction is described in [16][17][18].…”
