Abstract
Novel compounds particularly suitable as oxidation catalysts are prepared using critical amounts of uranium, antimony and tin.
Claims5
A novel catalyst defined by the following stoichiometry:
- USb.sub.a Sn.sub.b O.sub.8-12, wherein a is the number about 2.5 to about 1.5 and b is the number about 0.5 to about 1.5, with the atomic ratio of the sum of antimony and tin to uranium being about 2.5:1 to about 3.5:1.
A process for preparing a compound containing uranium, antimony and tin which comprises heating (1) oxides of uranium, antimony and tin, or (2) compounds of said elements that will decompose or be converted to said oxides during said heating, wherein the atomic ratio of antimony to uranium is about 2.5:1 to about 1.5:1, the atomic ratio of tin to uranium is about 0.5:1 to about 1.5:1 and the atomic ratio of the sum of antimony and tin to uranium is about 3.5:1 to about 2.5:1, in an atmosphere containing molecular oxygen at a temperature of at least about 800.degree. C. for about 15 minutes to about 24 hours.
