摘　　要：直接从SiO2 (白炭黑 )制备了高活性的五配位硅化合物 ,并用带环氧官能团的含卤化合物与活性五配位硅作用 ,衍生出带有环氧官能团的硅酸酯。借助于X 衍射法测试手段 ,对合成产物进行了分析。结果表明 ,高活性的五配位硅呈强碱性 ,吸水性强 ,吸收水分后很快分解还原成SiO2 和有机物。而在含卤化合物与活性五配位硅化合物作用生成硅酸酯后 ,即控制和消除了这种可逆反应 ,制备出了稳定的环氧硅酸酯。High reactive pentacoordinate silicon complexes were synthesized directly from SiO 2, and then reacted with halogen-containing compounds to get epoxide silicate, which were analyzed by X ray diffraction (XRD). Results showed that high reactive pentacoordinare silicon complexes presented property of strong alkalinity, hygroscopic, and quickly reduction to SiO 2 and organic substance as soon as it absorbed moisture, but epoxide silicate was stable.
