摘要：

This paper reports a new route for the intercalation of an ionic liquid, namely I-ethyl pyridinium chloride, into the interlamellar spaces of kaolinite. The intercalation was achieved using a kaolinite-urea intercalate as a starting material. The results of the XRD, FTIR, and TGA analyses confirmed the intercalation of ethyl pyridinium in the interlamellar spaces of kaolinite. C-13 CP/MAS spectra indicated the complete displacement of urea by ethyl pyridinium. Si-29 and Al-27 NMR spectra of the starting materials and the products are also discussed as well as the results of the elemental analysis of the produced nanohybrid material.
