【摘要】 通过γ-氨基丙基三乙氧基硅烷与固体光气反应,建立了一种生产γ-异氰酸酯丙基三乙氧基硅烷偶联剂的新方法。并用自制的这种偶联剂的苯胺衍生物对硅胶进行了功能化,结果表明所得到的产物为目标分子。制备反应中的溶剂可回收循环使用,此生产工艺有一定的应用前景。更多还原

【Abstract】 A new way to prepare γ-isocyanatepropyltriethoxysilane was established, which is on the basis of the reaction between γ-aminopropyltriethoxysilane and triphosgene in toluene. The product was comfired by functionalization of silica gel using γ-isocyanatepropyltriethoxysilane prepared with the approach established in this work. The solvent used for the reaction is recyclable. Therefore this technique has a good potentiality for practicable use.更多还原
