The adsorption of acetylacetone on layer silicates containing various cations has been studied by means of infrared spectroscopy, X-ray and thermal analyzer. An analysis of several split bands in the region of 1740-1520 cm^-1 was made. The split bands were attributed to the interaction of carbonyl with surface hydroxyl and cationic hydroxyl groups, and were responsible for the formation of acetylacetonate complexes between enolic or anionic acetylactone and metal cation in silicate layer.
