Effect of Intercalated Agents on Thermal Deintercalation of Kaolinite

Abstract:

A series of intercalated kaolinite with formamide, potassium acetate and acrylamide were prepared. The thermal deintercalation processes of these composites were studied using a combination of X-ray diffraction and thermal analysis technique. X-ray diffraction spectra showed acrylamide could be indirectly intercalated into kaolinite layers. The activatory energy of thermal deintercalation of acrylamide from kaolinite-potassium acetate composites was 15.60 kJ/mol, higher than that from kaolinite-formamide composites, 9.51 kJ/mol. The reason was that strong hydrogen bondings between acrylamide and potassium acetate were formed in kaolinite layers.
