Abstract
A process for the continuous preparation of a cumene feed for cumene oxidation from a fresh cumene stream and a recycle cumene stream containing trace quantities of at least one organic acid compound by a dilute caustic wash of the contaminated cumene streams followed by a water wash of the cumene streams in a single vessel with multiple contacting sections. A portion of the water wash is supplied by a waste water stream from an oxidate wash zone having trace quantities of cumene hydroperoxide.
