Alkylations of benzene in room temperature ionic liquids modified with HCl

Alkylations of benzene with dodecene and/or chloromethanes in the chloroaluminate room temperature ionic liquid modified with HCl as catalysts have been investigated. Different product distributions and enhanced activity, were respectively observed for these two alkylation reactions. This may be attributed to the superacidity of the ionic liquid induced by the presence of HCl. (C) 2001 Elsevier Science B.V. All rights reserved.
