METHOD FOR PREPARING AMMOXIDATION CATALYSTS

摘要

A method for preparing mixed vanadium, antimony and iron oxides, and the use thereof as alkane ammoxidation catalysts, are disclosed. According to the method for preparing said mixed oxide, respective vanadium, antimony and iron compounds are dissolved in at least one saturated alcohol or water, the resulting alcoholic or aqueous solution is contacted with an aqueous solution containing an ammonium salt to precipitate out the mixed oxide, and the resulting mixed oxide is separated and calcined.
