Abstract
A novel siliceous composition prepared by impregnating porous silica with aluminum hydride and subsequently heating the impregnated silica to a temperature of from about 300.degree. C. to about 900.degree. C. in a non-oxidizing environment. The composition is useful as a catalyst in reactions catalyzed by acid catalysts.
Claims12
A process for preparing a siliceous composition which comprises impregnating a substantially dehydrated amorphorous silica gel with aluminum hydride dissolved in an anhydrous, non-hydroxyl containing organic solvent, drying the impregnated silica to remove the solvent and subsequently heating the impregnated silica at a temperature of about 300.degree. to about 900.degree. C. in a non-oxidizing atmosphere.
