摘要：
The dimethyl sulfoxide (DMSO) molecules absorbed on the surface of kaolinite in kaolinite/DMSO compound formed using the DMSO intercalated into kaolinite was investigated by thermogravimetry-differential scanning calorimetry (TG-DSC) analysis and X-ray diffraction (XRD). The TG-DSC curves of the compound samples dried at 60°C for different time and with different rising rates of temperature were measured. The results show that the absorbed water and desorbed DMSO can be completely removed at 60°C for 24 h without affecting the intercalated DMSO. The temperature for the removal of DMSO molecules is 117°C. Based on the data of the thermal analysis, the molar ratio of Al2[SiO2O5](OH)4 and DMSO is 1.04:1. This conclusion considers the water in kaolinite/DMSO compound only is absorbed on the surface of kaolinite.
