三甲基叠氮硅烷的合成研究

Research on Synthesis of Trimethylsilane azide

以三甲基氯硅烷和叠氮化钠为原料,二氯甲烷为溶剂,碘化锌为助催化剂,聚乙二醇400为相转移催化剂,在无水条件下制备三甲基叠氮硅烷。实验考察了滴加时间、保温反应时间、溶剂量、助催化剂量、相转移催化剂量、放大效应等因素对产品收率的影响。反应过程和产品质量通过气相色谱法进行分析、检测。

To＇ synthesize trimethylsilane azide under the anhydrous condition with trimethylsilane chloride and sodium azide as raw materials, methylene chloride as the resolvent, zinc iodide as catalyst, PTC PEG400 as phase transfer catalyst. To investigate the influencing factors on the yield,such as reaction time,the amount of resolvent,and catalysts （zinc iodide, PCT PEG400）, amplification effect, and so on. To detemine the intermediate and final products by gas chromatography.
