Abstract:
1. A process for the preparation of phenol, comprising: hydrodeoxygenating one or more polyhydroxylated benzene derivatives or selectively hydroxylating benzene in the presence of a catalyst comprising: one or more multi-component metal oxides having at least one active oxide phase having a scheelite crystalline structure, and one or more materials with a non-scheelite crystalline structure or an amorphous structure, wherein the scheelite crystalline structure is one or more of the following compositions: wherein the selective hydroxylation of benzene is carried out by feeding oxygen or other oxidizing agents in lower or null amounts with respect to the stoichiometric quantity due to the hydroxylated benzene, and wherein the complementary stoichiometric oxygen is provided by the catalyst.
