| Abstract: | A new method is presented for the synthesis of pentacoordinate silicon complexes directly from residues left behind extracting of aluminum from bentonite by the low-temperature heating method. The optimum synthetic conditions were determined by experiments and the structure of products was analyzed by IR and XRD. The results show that when alkali metal hydroxides are used as the reaction medium, the products are pentacoordinate silicon complexes and under the optimum synthetic conditions, the yields of sodium salt and lithium salt are greater than 63.0% and 44.9%, respectively. |
