N2 - Efficient two-steps method for the synthesis of octa(aminopropylsilsesquioxane)(OAPS) was described in this paper. The chloride salt of OAPS was prepared by the hydrolytic condensation of γ- aminopropyltriethoxysilane in methanol, with hydrochloric as a catalyst. The influence of several processing on the synthesis has been ascertained. The chloride salt of OAPS can be obtained in 42.1% yield after a reaction time of 18h, which is a much shorter than that required for traditional method. Neutralization of the chloride salt of OAPS to OAPS was accomplished by eluting solutions of this hydrochloride in methanol through a column of Amberlite 717 ion-exchange resin. The structure of products was determined by FTIR, MS, Elemental analysis, 1H, 13C, and 29Si NMR. TG curve of OAPS shows that the compound has high decomposition temperature and higher char residue yield.
