Resumo: A hydrated kaolinite-methanol intercalation compound (Kaol-MeOH (hydrated)) was synthesized by utilizing kaolinite/dimethyl sulfoxide intercalation compound (Kaol-DMSO) as an intermediary, and further displacement intercalation with butyl trimethylammonium chloride (BTAC) was also carried out. The obtained samples were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Results showed that the d001 value of the Kaol-MeOH (hydrated) could be arbitrary values between 0.86 and 1.08 nm, which could be caused by the hydrogen-bonded MeOH or water molecules between the interlayer spaces of methoxy-modified Kaol. Furthermore, this part of interlayer molecules could be removed by heating and have no obvious effect on the subsequent intercalation reaction. In addition, the time required for Kaol-MeOH (hydrated) preparation was drastically shortened to 3 days, which greatly reduces the time-consuming for the preparation of subsequent compounds.
