Abstract

1314578 Olefin ammoxidation catalysts UBE INDUSTRIES Ltd 4 Aug 1970 [5 Aug 1969] 37639/70 Heading B1E [Also in Division C2] A catalyst for use in the conversion of propylene to acrylonitrile comprises a compound (for example a heteropoly salt) of molybdenum, bismuth, antimony and oxygen and/or a mixture (for example a solid solution) of oxides of molybdenum, bismuth and antimony, the catalysyt containing, per 100 atoms of total molybdenum, bismuth and antimony, from 5 to 40 atoms of molybdenum, from 35 to 65 atoms of bismuth and from 5 to 60 atoms of antimony, with the proviso that the catalyst is not a catalyst which contains relative atom percentage proportions of molybdenum (α), bismuth (#) and antimony (y) represented by any point which lies on, or within the area defined by, the lines connecting point A (α:#:y=25:50:25), point B(α:#:y=40:55:5) and point C (α:#:y=40:50:10) in Figure 1. The catalyst may be supported on carrier material, for example selected from silica, alumina, silica-alumina and silicates (none specified) and/or additionally may comprise at least one element selected from phosphorus, arsenic, boron, sulphur, tellurium, vanadium, tin, cerium and lenthenum in combined, for example oxidic, form. Examples relate to the preparation of unsupported catalysts (Examples 1 to 24, 27 and 28 and Comparative Examples 1 to 10) and silica-supported catalysts (Examples 25 and 26 and Comparative Examples 11 to 15) by generally conventional methods from molybdenum trioxide or ammonium molybdate, bismuth oxide or bismuth nitrate, antimony trioxide (provided for example by hydrolysis of antimony trichloride) and colloidal silica, the catalysts of the Comparative Examples containing molybdenum, bismuth and antimony in relative proportions which do not satisfy the aforementioned requirement. Disclaiming reference is made to Specifications 1222946 and 1233491.
