Abstract: A catalyst is described which has a catalytically active composition which contains a phase A and a phase B in the form of three-dimensional delimited regions, wherein phase A is a silver-vanadium oxide bronze and phase B a mixed oxide phase based on titanium dioxide and vanadium pentoxide. The catalyst serves to prepare aldehydes, carboxylic acids and/or carboxylic anhydrides from aromatic or heteroaromatic hydrocarbons by gas phase oxidation.

Abstract: Multi-metal oxides based on silver, vanadium and optionally other metal(s) also contain phosphorus, arsenic, antimony and/or bismuth. Multi-metal oxides consisting essentially of compounds of formula Aga-cQbMcV2Od.eH2O (I), in which a = 0.3-1.9; Q = phosphorus, arsenic, antimony and/or bismuth; b = 0.001-0.3; M = lithium, sodium, potassium, rubidium, cesium, thallium, magnesium, calcium, strontium, barium, copper, zinc, cadmium, lead, chromium, gold, aluminum, iron, cobalt, nickel and/or molybdenum; c = 0-0.5; (a-c) = not less than 0.1; d = a number determined by the valency and occurrence of elements other than oxygen; e = 0-20. The powder X-ray patterns of these oxides (I) show diffraction lines at lattice plane separations (d) of 15.23 \! 0.6, 12.16 \! 0.4, 10.68 \! 0.3, 3.41 \! 0.04, 3.09 \! 0.04, 3.02 \! 0.04, 2.36 \! 0.04 and 1.80 \! 0.04 Angstrom . Independent claims are also included for: (a) a method for the production of (I) by heating a suspension of vanadium pentoxide in a liquid with a solution of silver salt and the element Q or a compound of Q, optionally with the addition of a compound of M; (b) pre-catalysts for the production of shell catalysts for the partial gas-phase oxidation of aromatic hydrocarbons with molecular oxygen-containing gas, comprising an inert, non-porous support coated with one or more layers of (I); (c) shell catalysts for the above application, made from (I) and an inert support, in which the catalytically active material in the shell(s) contains 30-100 wt% silver-vanadium bronze(s) with an Ag:V atom ratio of 0.15-0.95 and a BET surface of 2-100 m /g; (d) a process for the production of aldehydes, carboxylic acids and/or anhydrides by partial oxidation of aromatic hydrocarbons (see above) using shell catalysts as in (c) in the presence or absence of other shell catalysts for this application containing vanadium pentoxide and anatase as active components (which are, if present, used in a combined catalyst bed).

Abstract: Shell catalyst for catalytic gaseous phase oxidation of aromatic hydrocarbons, which contains in an inert non-porous support a catalytically active material with a given content of vanadium oxide, titanium oxide, a cesium compound, a phosphorus compound and antimony oxide, wherein the catalytically active material is applied in two or more layers and wherein the outer layers have 50 to 100 % less antimony oxide content than the inner layer or layers and wherein the amount of catalytically active material of the inner layer or layers accounts for 10 to 90 % by weight of the overall amount of total catalytically active material. The invention also relates to a method for the production of said catalysts and to a method for the production of carboxylic acids and/or carboxylic acid anhydrides and especially phthalic acid anhydride using said catalysts.
