Montmorillonite-n-alkylamine intercalation compounds were prepared by solid-solid reactions. The mixtures of Na-or Ca-montmorillonite and n-alkylamines (ntetradecylamine, n-hexadecylamine, and n-octadecylamine) were ground under a dry air atmosphere at ambient temperature. The basal spacings of the mixtures increased after grinding for only a few minutes. The basal spacings varied with the alkyl chain length of the guest n-alkylamines. The relation between the basal spacings and alkyl chain length implied that the intercalated alkylamines formed bilayers with their fully extended alkylchains inclined to the silicate sheet. The products were essentially identical to those prepared by conventional solid-liquid reactions.
