phenols can be prepared by the following methods. 1) hydrolysis of cholorobenzene: in this process, chlorobenzene which can be obtained by the cholorinationof benzene, is heated at 350*C under high pressure with aqueous sodium hydroxide to get sodium phenoxide, which on acidification yields phenol. 2) pyrolosis of sodium benzenesulphonate: this, the first commercial process for industrial synthesizing phenol , was developed in Germany in 1890. sodium benzenesulphonate is melted with sodium hydrooxide at 350*C to produce sodium phenoxide, which on acidification yields phenol. 3) oxidaton of cumene: benzene is alkylated with propene to produce cumene, which is oxidized with air to produce cumene hydroperoxide, which on treatment with 10% sulfuric acid undergoes a hydrolytic rearrangement to yield phenol and acetone.
