Abstract
Aromatic hydrocarbons are alkylated with relatively long chain alkylating agents, e.g., C.sub.8 + olefins, at mole ratio of aromatic to alkylating agent of not greater than about 5 in the presence of, as catalyst, a Lewis acid-promoted amorphous, porous inorganic oxide such as silica to provide long chain alkyl aromatic products which are useful, inter alia, as lubricating oil stocks.
