Abstract
The present invention is concerned with an improved process for the molecular oxygen oxidation of ethylbenzene in the liquid phase to ethylbenzene hydroperoxide. The improved process is particularly concerned with carrying out the oxidation in a series of separate oxidation zones at substantially constant pressure with the temperature being progressively reduced from zone to zone in the liquid phase, the temperature reduction and control being accomplished by recycle of inert gases.
