In the ferric sulfate solution, benzene can be oxidized to phenol with a good yield above 170°C, when not irradiated, but at lower temperatures, when irradiated. In the ferrous sulfate solution, the yield of phenol is independent of irradiation, and somewhat larger than in the irradiated ferric sulfate solution. Such a high yield of phenol is due to the complexing of hydroxycyclohexadienyl peroxy radical, produced with OH radical and oxygen dissolved, with ferrous ions.
