胺化反应时间与N-β-氨乙基-γ-氨丙基甲基二甲氧基硅烷收率及黄变现象的研究

Study of Relation of Amination Time with Yield of N- β -aminoethyl- γ - aminopropylmethyldimethoxysilane and Yellow Discoloration

对合成Ｎ－β－氨乙基－γ－氨丙基甲基二甲氧基硅烷工序中的胺化反应进行了研究，发现生成铵盐的量与反应温度及时间无关；控制一定的反应温度与时间，对产品收率没有影响，但能减少黄色物质的生成。

The amination reaction in the synthesis of DL-103(N- β -aminoethyl- γ -aminopropylmethyldimethoxysilane)was studied,and it was found the reaction temperature and time had no effcts on the amounts of the formed aminium salt;to control the reaction temperature and time in a proper region had no effect on the yield of DL-103,but could decrease yellow discoloration.
