Sb2O3 [1309-64-4] is oxidized to Sb2O5 with H2O2 at 40-100° and then treated with metal salts, oxides, or hydroxides to give mixed oxides, useful as oxidn. catalysts for org. compd. Thus, an aq. suspension of Sb2O3 was treated 1 hr at 90° with 30% aq. H2O2, aq. Fe(NO3)3 [10421-48-4] was added, and the resulting mixt. dried 4 hr at 120-130° and calcined 4 hr at 700° to give 4Sb2O5.Fe2O3 [58244-89-6] which catalyzed the ammoxidn. of propylene [115-07-1] to acrylonitrile [107-13-1] at 80.3% yield and 57.9% selectivity. Unit cell dimensions are given for crystals of mixed oxides of Sb and Sn, Mn, Ba, Ag, Ca, Mg, Al, Cr, Pb, La, Co, or Ni.
