THE INDUCTION PERIOD OF OXIDATION OF ETHYLBENZENE AS A STAGE OF FORMATION OF THE ACTIVE FORM OF THE CATALYST
In this work, the basic factors affecting the accumulation of trivalent cobalt in the oxidation reaction of ethyl benzene model were presented. It is known that, the conversion of hydrocarbon in the liquid phase oxidation reaction begins after transformation of the catalyst from divalent to trivalent form. The stage of accumulation of active form of the catalyst is considered to be the induction period of the process, which can range from few minutes to hours for various hydrocarbons and catalysts. The study of oxidation of cobalt (II) ion was carried out by varying the initial concentrations of cobalt (II) stearate, the oxygen contents in the oxidant gas in the presence and the absence of additives of intermediate products of hydrocarbon oxidation.
