Abstract

Ethylammonium-layered aluminosilicates intercalates were prepared by ion exchange reaction between the layered silicates with different layer changes density of 0.32∼0.41 e per unit formula and ethylammonium chloride. A kinetic study on the thermal deintercalation of the ethylammonium-layered silicate intercalates was carried out by range of 350℃ to 480℃ (heating rate of 10℃/min). Based on the Ozawa's method, the activation energies of the thermal deintercalation reaction were estimated as 171.2∼133.0 kJ/mol, which increase linearly with the layer charge densities.
