ABSTRACT:
Benzene is catalytically oxidized in the vapor phase with oxygen in the presence of an alcohol to be converted to phenol. The catalyst used is represented by the formula: M.sub.a Ag.sub.b P.sub.c O.sub.d wherein M is selected from zinc, titanium, zirconium, tin, bismuth and vanadium, Ag is silver, P is phosphorus and O is oxygen, and a=1, b=0.005.about.5 and c=0 to 6. Phenol is obtained at an enhanced yield even though the catalytic oxidation is carried out at a relatively low temperature as compared with conventional catalytic oxidation processes.
