Catalysts of general formula (I): [AaBbOx]p [CcDdFeeCofEiFjOy]q, in which the variables have the following meanings: A = bismuth, tellurium, antimony, tin and/or copper; B = molybdenum and/or tungsten; C = an alkaline metal, thallium and/or samarium; D = an alkaline earth metal, nickel, copper, cobalt, manganese, zinc, tin, cerium, chromium, cadmium, molybdenum, bismuth and/or mercury; E = phosphorus, arsenic, boron and/or antimony; F = a rare-earth metal, vanadium and/or uranium; a = 0.01 to 8; b = 0.1 to 30; c = 0 to 4; d = 0 to 20; c = 0 to 20; f = 0 to 20; i = 0 to 6; j = 0 to 15; x and y are figures determined by the valency and frequency of the elements in (I) differing from oxygen and p and are figures, the ration p/q of which lies in the range from 0.001 to 0.099, and a process for producing said catalysts, their use for the ammono-oxidation, oxidation or dehydrogenation of ethylenically unsaturated compounds and a process for ammono-oxidation, oxidation or oxidative dehydrogenation of ethylenically unsaturated compounds in the presence of the catalyst of the invention.

L'invention concerne des catalyseurs de la formule générale (I): [AaBbOx]p [CcDdFeeCofEiFjOy]q, dans laquelle les variables ont la notation suivante: A désigne bismuth, tellure, antimoine, étain et/ou cuivre; B désigne molybdène et/ou tungstène; C désigne un métal alcalin, thallium et/ou samarium; D désigne un métal alcalino-terreux, nickel, cuivre, cobalt, manganèse, zinc, étain, cérium, chrome, cadmium, molybdène, bismuth et/ou mercure; E désigne phosphore, arsenic, bore et/ou antimoine; F désigne un métal des terres rares, vanadium et/ou uranium; a vaut entre 0,01 et 8; b vaut entre 0,1 et 30; c vaut entre 0 et 4; d vaut entre 0 et 20; e vaut entre 0 et 20; f vaut entre 0 et 20; i vaut entre 0 et 6; j vaut entre 0 et 15; x, y sont des nombres déterminés par la valence et la fréquence des éléments de (I) différents d'oxygène et p, q sont des nombres dont le rapport p/q est compris entre 0,001 à 0,099. L'invention concerne également un procédé de production de ces catalyseurs, leur utilisation dans l'ammono-oxydation, l'oxydation et la déshydrogénation de composés insaturés éthyléniquement, ainsi qu'un procédé d'ammono-oxydation, d'oxydation ou de déshydrogénation de composés insaturés éthyléniquement en présence des catalyseurs réalisés selon l'invention.
