Cumene on reaction with oxygen

WebCumene (isopropylbenzene) is oxidised in the presence of air to produce cumene hydroperoxide. Phenol is produced by further treating cumene hydroperoxide with dilute acid. One of the by-products of this process is the production of acetone in large amounts. Therefore, it is necessary to purify the phenol that results from these processes. 2.
