Abstract: Antimony-based oxide complex catalysts are improved by adding to these catalysts an antimony-containing compound such as Sb 2 O 3 , in an amount of 0.1 to 25% based on an atomic basis of the antimony relative to the antimony already present in the catalyst. In this way a catalyst is produced which gives improved yields for example in the procuction of acrylonitrile by the ammoxidation of propylene.
