Abstract

Improvements in supported catalysts for the oxidation of O-xylene or naphthalene to phthalic anhydride, composed of an inert, non-porous support and of an active mass applied on the thin layer, containing 1 to 40% by weight of vanadium pentoxide and 60 to 99% by weight of anatase, with a content of vanadium pentoxide, based on the supported catalyst, of 0.05 to 4% by weight; characterized in that 0.01 to 0.15% by weight, based on anatase, of sodium or potassium in the form of their sulfur-free compounds is applied to the catalytically active mass.
