摘 要:通过两种接枝方法合成了SBA-15分子筛表面化合物,分别对其进行了红外、元素分析、原子发射光谱、N2吸附-脱附等结构表征。且将这两种化合物分别应用于催化硅腈化反应,发现超声接枝的化合物具有较高的催化转化率。比较而言,超声接枝法具有反应条件温和、操作方便及费时少等优点。The SBA-15 supported compounds were synthesized by two methods,and were characterized by FT-IR,ICP-AES,element analysis and nitrogen adsorption-desorption,respectively.Utilizing the two compounds as catalysts,respectively,the cyanosiylated reaction of benzaldehyde with TMCN was probed.The results showed that the much higher catalytic conversion could be obtained when used the compound,which was grafted under the ultrasonic radiation at room temperature.It was found that the ultrasonic synthetic method had some advantages,such as mild reaction conditions,convenient operation,saving time and so on.
