PROCESS FOR THE PREPARATION OF SUPPORTED MOLYBDENUM/TUNGSTEN COMPOSITIONS AND THEIR USE FOR THE ISOMERIZATION AND DISPROPORTIONATION OF OLEFINS

摘要

Novel compositions are prepared by impregnating inert supports with H4Mo(CN)8 and/or H4W(CN)8 and subsequently activating by heating in an inert environment at about 400 DEG -600 DEG C. The materials, particularly when supported on aluminous or siliceous supports, are useful as catalysts for simultaneously isomerizing and disproportionating olefins.
