1,168,279. Oxidation catalysts. MONTECATINI EDISON S.p.A. 22 Dec., 1966 [28 Dec., 1965], No. 57477/66. Heading B1E. [Also in Division C2] Oxidation catalysts comprise the elements Te, Sb and O, the atomic ratio of Te and Sb being from 9:1 to 1:1 and the oxygen being present in an amount sufficient to insure that both the elements Te and Sb exist as oxygenated compounds. The catalysts may be supported on SiO 2 , A1 2 O 3 or fireclay. In examples SiO 2 is impregnated with H 2 TeO 4 and SbCl 5 and fired. |
