ABSTRACT:
Benzene and dialkylbenzene are transalkylated to alkylbenzene by contact at temperatures of 175.degree. C. to 450.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.
