ABSTRACT:
High surface area oxidative dehydrogenation catalysts which are suitable for converting C.sub.4 to C.sub.8 mono-olefins to diolefins are disclosed, comprising the oxides of an alkali metal, vanadium, phosphorus, and preferably tin in combination with a crystalline silica having a surface area between 30 M.sup.2 /g to 450 M.sup.2 /g and wherein the vanadium has an average valence in the range of from 3.5 to 4.95.
