Dynamics of n-Alkylammonium Ions Intercalated in Saponite

Organo-clay composites of saponite intercalated with several kinds of n-alkylmono- and diammonium ions were prepared, and the dynamic properties of the intercalated cations were investigated by solid state NMR. It was found that the cationic motions are characterized by distributed correlation times due to an environmental inhomogeneity of the interlayer space of saponite.
