PCT No. PCT/FR96/01510 Sec. 371 Date Jun. 11, 1998 Sec. 102(e) Date Jun. 11, 1998 PCT Filed Sep. 27, 1996 PCT Pub. No. WO97/12839 PCT Pub. Date Apr. 10, 1997The present invention relates to a process for the preparation of mixed vanadium, antimony and iron oxides and to their use as catalysts for the ammoxidation of alkanes. The process for the preparation of a mixed oxide defined above is characterized in that: respective vanadium, antimony and iron compounds are dissolved in at least one saturated alcohol or in water, the alcoholic epsilon olution or the aqueous solution thus obtained is brought into contact with an aqueous solution containing an ammonium salt, in order to precipitate the mixed oxide, the mixed oxide obtained is separated and calcined.
