Abstract
In the presence of FeCl3·6H2O/C catalyst, octa (nitrophenyl) polyhedral silsesquioxane (ONPS) was successfully reduced to octa (aminophenyl) polyhedral silsesquioxane (OAPS) using hydrazine hydrate with a yield of 93%. Structure and properties of OAPS are characterized by means of FTIR, NMR, elemental and thermal analysis. Its temperature corresponding to 5% weight loss is 338.8°C. This shows that OAPS has a high stability to heat. At the same time, mechanism of the reduction of ONPS by hydrazine catalyzed by FeCl3/C was proposed.
