摘要：
The thermal transformations in silicas covalently modified by aminopropyl groups and their nitrates and chlorides were studied by thermogravimetry method. The nature of thermal decomposition process of aminosilica in 310-340°C temperature interval differs from its explanation given in literature. It was demonstrated that the aminosilica nitrate decomposes at 225°C with the formation of aldehyde groups.
