3-氨丙基三硅氧烷合成的研究

Study on Synthesis of (3-aminopropyl) Trisiloxane

以氨丙基二乙氧基甲基硅烷(SG-Si902)、六甲基二硅氧烷(MM)为原料,通过平衡催化合成了氨丙基三硅氧烷,去除反应过程中的副产物来提高反应产率.并通过核磁共振和质谱等手段对反应产物的结构进行了表征.

3-aminopropyl trisiloxane is synthesized by the reaction of 3-aminopropyl methyldiethoxysilane with hexamethyldisiloxane using tetramethylammonium hydroxide as a catalyst.It improves the yield of 3-aminopropyl trisiloxane through eliminating the by-products.The products are identified by NMR and MS.
