Abstract: A process for the manufacture of phthalic anhydride by oxidizing o-xylene and/or naphthalene over a supported catalyst containing vanadium pentoxide and titanium dioxide, at from 350.degree. to 500.degree.C, in which the o-xylene or naphthalene is passed, with an oxygen-containing carrier gas, over the catalyst, and in which the catalyst in the first 25-50 per cent by volume of the total catalyst volume, in the direction of flow of the mixture of .alpha.-xylene or naphthalene and carrier gas, containe from 0.001 to 0.3 per cent by weight, based on titanium dioxide, of rubidium, but no phosphorus, in the active composition, whilst the remainder of the catalyst contains from 0.02 to 0.8 per cent by weight, based on titanium dioxide, of phosphorus, but no rubidium, in the active composition.
