This paper summarizes the main synthesize methods of phenol,such as benzene sulfonic acid, chlorobenzene hudrolyze,cyclohexanone-cyclohexanol,cyclohexanone-cyclohexanol:toluene-benzoic acid, cumene and direct catalytic hydroxylation of benzene to phenol etc.It also analyzes the atom utilization by the perspective of green chemistry and points out the advantages and disadvantages of all the methods.Of all the methods cumene is the most effective in the world and its production accounts for 92%.Now phenol synthesize is developing to the technic of little and no producing waste,high atom utilization and no co-production of acetone that is called direct catalytic hydroxylation of benzene to phenol.
