WebCorrect option is C) To prepare phenol, cumene is first oxidized in the presence of air to cumene hydroperoxide. Now, cumene hydroperoxide is treated with dilute acid to prepare phenol and acetone as by-products. By this method, acetone is obtained in large quantities. So, the correct option is 'C'. Solve any question of Alcohols Phenols and ... WebNov 15, 2001 · Industrial phenol-production process generally involves the following three steps (Scheme 1) [1]: 1. Isopropylation of benzene to cumene. 2. Auto-oxidation of cumene to cumene hydroperoxide (CHP). 3. Acid cleavage of CHP to phenol and acetone. Among these three steps, the cumene auto-oxidation step affords the lowest efficiency [2].
