ABSTRACT:
A process is described for the preparation of phenol by the hydrodeoxygenation of polyhydroxylated benzene derivatives or by the selective hydroxylation of benzene under depletive conditions, characterized in that the above-mentioned reactions are carried out in the presence of a catalyst based on multi component metal oxides comprising at least one metal selected from the groups VB, VIB, VIII, IB, IIB, IVA, VA.
