双羟基四配位硅单体的合成

Synthesis of Bishydroxyl Tetracoordinate Silicon

以无定型二氧化硅为起始原料 ,与乙二醇、氢氧化钾反应 ,生成高反应活性的五配位硅钾化合物 ,并以此为原料与 2 氯乙醇反应制备了双羟基四配位硅化合物 .探讨了不同反应条件 (如温度、不同反应物摩尔比、催化剂等 )对该反应的影响 ,并对合成的化合物做了红外光谱、核磁共振 (1 H ,1 3C)、元素分析、能谱元素分析等结构表征 .

A highly reactive pentacoordinate organic silicon complex was prepared by reaction of natural silica with ethylene glycol in the presence of potassium hydroxide. Treatment of this pentacoordinate silicon complex with ClCH2CH2OH gave a bishydroxyl tetracoordinate silicon, which was characterized by FTIR, NMR, EDS etc.
