Abstract

Process for the preparation of a catalyst in powder form, consisting of a mixture of iron oxides, bismuth, molybdenum and phosphorus on silicic acid as support, by modification with iron of a bismuth phosphomolybdate catalyst/silicic acid previously formed, characterized in that a bismuth phosphomolybdate/silicic acid catalyst, previously formed, is impregnated in a homogeneous manner with the aqueous solution of an iron salt, preferably trivalent iron nitrate, using a volumetric amount of solution such that corresponds to about 1 to 2.5 times the previously determined pore volume of the bismuth phosphomolybdate/silicic acid catalyst; because the catalyst containing wet iron is slowly dried, at about 120 to 250ºC with simultaneous decomposition of the iron salt to form iron oxide; and in that the dried catalyst is sintered at about 600 to 700º c.
