ABSTRACT:
The instant invention relates to a process for the oxidation of benzene to phenol which comprises contacting benzene and molecular oxygen with a dihydrodihydroxynaphthoquinone, optionally in the presence of an oxidation catalyst, and subsequently separating from the reaction product phenol and the corresponding naphthoquinone. The by-product napththoquinone is suitably recycled to the benzene oxidation step by hydrogenating the naphthoquinone to the dihydrodihydroxynapththoquinone.
