Abstract

The oxidation of ethylbenzene to products comprised of ethylbenzene hydroperoxide and acetophenone is modified in order to enhance acetophenone production by reducing the alkali content of the oxidation mixture below 0.1 ppm and by incorporation of 0.05 to 2 wt. % water in the oxidation mixture.
