Various clay minerals of the smectite group could form intercalation compounds with acrylamide by solid-solid reaction at room temperature and within a few minutes of contacting the reactants. Taeniolite, a synthetic fluor-mica with a higher layer charge density than smectites, gave an only incomplete intercalation. The propensity of the minerals for intercalating acrylamide was correlated with their reactivity towards ethylene glycol. Because of their rapidity and simplicity, solid-solid reactions provide a new way of introducing organic species into the interlayer spaces of smectites.
