Explain the preparation of phenol from cumene.

Solution

Preparation of phenol from cumene $$\rightarrow$$
To prepare phenol, cumene is first oxidised in the presence of air to cumene hydroperoxide.
$$\underset{\left( \text{Isoprophyl benzene} \right)}{\text{Cumene}} \xrightarrow[]{{O}_{2}} \text{Cumene hydroperoxide}$$
Now, cumene hydroperoxide is treated with dilute acid to prepare phenol and acetone as by-products.
$$\text{Cumene hydroperoxide} \xrightarrow[323-363 \; K]{{H}^{+}} \text{Phenol} + \text{Acetone}$$
By this method, acetone is obtained in large quantities.
