Na-Montmorillonite (Na-MMT) was intercalated with two series of dialkyl imidazolium salts. The series were selected by varying the alkyl substitutions at 1 and 3 positions of imidazole ring viz. 1-alkyl 3-methyl imidazolium salts in one series and 1-methyl 3-alkyl imidazolium salts in other series. Length of the alkyl chain was varied. Gallery heights of these imidazolium intercalated montmorillonites (I-MMT) were deduced by X-ray diffraction analysis (XRD). Thermal stability and organic loading of I-MMT were studied using thermogravimetric analysis. Vibration bands due to organic inclusion within montmorillonites (MMT) were characterized by FTIR measurements. TEM analysis disclosed the microstructural changes of MMT after intercalation with organic intercalates. The properties of I-MMT were found to be influenced by alkyl chain length and their variation in 1 and 3 positions of imidazole ring.
