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