Summary
-
1.
In the oxidation of ethylbenzene catalyzed by nickel stearate, the activity of the catalyst gradually falls as a result of reaction of nickel stearate with acids formed during, the oxidation.
-
2.
The anomalous course of the kinetic curve of hydroperoxide accumulation during the catalyzed reaction is associated with deactivation of the catalyst.
