Since the 1950s, the cumene-to-phenol process is the predominant synthetic route for the production of phenol with acetone as the co-product. Cumene is oxidized with oxygen to form cumene hydroperoxide (CHP). The peroxide is subsequently decomposed to phenol and acetone, using sulfuric acid as a catalyst.
