| Abstract: | A series of organophilic bentonite(Ben) were prepared from different type bentonite by cation exchange with alkylammonium onium ions and alkylamine, and characterized by FTIR, XRD and TEM etc. The FTIR spectrogram showed that the organic reagents had intercalated into the layers of Ben. Spacing of layers of Ben was detected using X-ray diffractometer and was observed to have increased from 1.48 nm to 1.76～4.06nm. The results show that organophilic Ben wth large spacing of layers can be prepared starting with Ben having high exchange capacibility and long-chain alkylammonium onium ions to intercalate. |
