Abstract: Thermal analysis (TG, DTG) and infrared absorption spectra were used to study the interactions of pyridine, 4-methylpyridine, and 4-ethylpyridine with Co-exchanged montmorillonite. It is shown that the bonds between the derivatives of pyridine and the montmorillonite exhibit predominantly the Lewis acid character. The total amount of pyridines inserted in the porous structure of montmorillonite increases in the following sequence: unsubstituted, 4-methyl-, 4-ethylpyridine.
