Abstract

Oxidation of o-xylene and/or naphthalene in vapour phase to phthalic anhydride is effected in the presence of V2O5 and H3BO3 and/or a borate. Oxidation may be effected in a fixed or fluidized bed at 420-430 DEG C., with an air : o-xylene ratio of 150 : 1 and a throughput of 400-600 litres/hours.ALSO:An oxidation catalyst comprises V2O5 and 0,2-10% boric acid and/or salt thereof. Additionally the catalyst may contain Co, Mo, W, Ce, U, Sn and/or Ag.
