ABSTRACT:
A process is disclosed for the catalytic hydroxylation of aromatic hydrocarbons which comprises contacting aromatic feedstock with oxidant comprising molecular oxygen, under suitable reaction conditions, in the presence of a catalyst comprising three essential components: a support; transition metal selected from the group consisting of vanadium, niobium, copper, palladium, nickel and silver, or combinations thereof, and a promoter comprising a multidentate chelating, binucleating ligand. The catalysts may further comprise additional metal ions. The process is particularly suited, for example, to the one-step conversion of benzene to phenol.
