| Abstract: | A new method is presented for synthesis of organosilicon compounds directly from precipitated white carbon black by reduced pressure distillation. The optimum synthetic conditions are determined and the structure of products is analyzed by IR and XRD. The results show that when alkaline earth metal oxides are used as the medium, the products are hexacoordinate silicon complexes, and that under the optimum synthetic conditions, the conversion yields of barium salt and calcium salt are greater than 90% and 60% respectively. |
