Systems and methods for the production of phenol and acetone from cumene oxidation products. One method includes reacting cumene and an oxidizing agent to produce a cumene oxidation product including cumene hydroperoxide and dimethyl benzyl alcohol, converting at least a portion of the dimethyl benzyl alcohol to cumene hydroperoxide by reacting the at least a portion of the dimethyl benzyl alcohol with hydrogen peroxide in both an organic phase and an aqueous to produce a converted cumene oxidation product, and cleaving the converted cumene oxidation product to produce an output product including one or more of phenol, acetone, and alpha-methylstyrene.
