Abstract

Abstract Acidities of various ion-exchanged clay montmorillonites in organic media are compared by use of the reaction of a primary alcohol with allyltrimethylsilane. The order of catalytic activities of the montmorillonites coincide with a sequence of hydration enthalpy of exchanged cations in the clays.
