Abstract

The initial stages of mechanical activation of the layered silicates with higher alcohols and hydroxyacids are investigated by means of IR spectroscopy and X-ray phase analysis. The formation of new materials is established; they are dispersed layered mechanocomposites formed due to neutralization of the active centres of basic character on the silicate surface by the protons of carboxylic groups of hydroxyacids or hydroxyl groups of higher alcohols. Hydroxyl groups of acid do not participate in the reaction with silicates. They are likely to form hydrogen bonds both with hydroxyl groups of silicates and with water molecules
