    • The present invention relates to a process for preparing hydroxylated aromatics by using hydrogen and oxygen and more particularly, to a process for preparing hydroxylated aromatics by using hydrogen and oxygen with a two-component heterogeneous catalyst. One component consists of porous catalyst containing one of Group VIII B transition metals such as Pd, Pt, Au and Cu, and hydrogen transfer organic compounds such as anthraquinone. The other component consists of a catalyst containing a transition metal selected from Ti, V, and Sn with tetrahedral coordination geometry. The main advantages of this new catalytic system are to 1) overcome the drawbacks of liquid phase oxidation using conventional homogeneous catalysts, 2) avoid use of expensive hydrogen peroxide as an oxidant, and 3) improve the selectivity of the reaction.
