Shape-selective dissociative adsorption of alcohols on 1-butyl-3-methylimidazolium-exchanged mordenite zeolite

Dissociative alcohol adsorption was investigated on 1-butyl-3-methylimidazolium ([bmim]) exchanged mordenite (HM20) by FT-IR. Results indicated that the generation of acidic OH groups is attributable to the dissociative adsorption of alcohols on [bmim]M20 and alcohol adsorption onto the acidic OH groups. Shape-selective adsorption into the [bmim]M20 micropores was revealed for the alcohols examined.
