格氏法制备烯丙基硅烷红外表征及工艺研究

IR characterization and technology research of allylic silane prepared with Grignard method

使用格氏法制备了烯丙基硅烷,对所得产品进行红外光谱表征,确定了其中具有烯丙基的C=C双键特征峰,证明了反应的可行性;表征了不同阶段馏分的组成并分析推测了其中可能发生的副反应和可能存在的副产物,根据分析结果提出了改进合成及蒸馏工艺条件的方法。

Allylic silane was prepared with Grignard method and characterized the product with IR.The IR spectra of product appeared double bond of carbon characteristic peak for allylic silane.The result proved feasibility of this reaction.The distillates of different stage were characterized and side reaction and by-product were inferred.As the result of analysis we put forward the methods which improve technology condition of ditillation and synthesis.
