    摘要： The present invention relates to a catalyst for preparing phthalic anhydride by gas phase oxidation of o-xylene and/or naphthalene, comprising at least three catalyst zones which have different compositions and, from the gas inlet side toward the gas outlet side, are referred to as first, second and third catalyst zone, the catalyst zones having in each case an active composition comprising TiO2 with a content of Na of less than 0.3% by weight, and the active composition content decreasing from the first catalyst zone disposed toward the gas inlet side to the third catalyst zone disposed toward the gas outlet side, with the proviso that (a) the first catalyst zone has an active composition content between about 7 and 12% by weight, (b) the second catalyst zone has an active composition content in the range between 6 and 11% by weight, the active composition content of the second catalyst zone being less than or equal to the active composition content of the first catalyst zone, and (c) the third catalyst zone has an active composition content in the range between 5 and 10% by weight, the active composition content of the third catalyst zone being less than or equal to the active composition content of the second catalyst zone. Also described is a preferred process for preparing such a catalyst and the preferred use of the titanium dioxide used in accordance with the invention.
