Abstract

See full text

Relatively long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively long chain alkylating agent under alkylation reaction conditions in the pressure of a layered material as an alkylation catalyst. The layered material contains titanate in the layers and oxide pillars separating the layers. The layers also contain vacancies and/or metals incorporated therein.
