Abstract
A catalyst which is suitable as an oxidation catalyst, especially in the preparation of naphthoquinone or phthalic anhydride from naphthalene and molecular oxygen and which contains the elements Si, V, S, O and at least one alkali metal, is obtained by employing silicic acid having a mean grain size of < 50 mu m and an alkali metal content of < 2% by weight, calculated as Na2O and based on SiO2. The vanadium, the sulphur and the oxygen can be added in the form of a sulphuric vanadyl oxalate solution. The aqueous mixture is then dried at from 50 to 200 DEG C, and is heated to a higher temperature or calcined if required.
