Abstract
Dialkylbenzene is isomerized by contact at 350.degree. C.-600.degree. C. with 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.
Claims11
A process for isomerizing dialkylbenzenes which comprises contacting at about 350.degree. to about 600.degree. C. the dialkylbenzene with a catalyst prepared by a process 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.
