双功能硅烷化修饰MCM－41固载Cosalen催化环己烷氧化
采用双功能硅烷化试剂γ－氨丙基甲基二乙氧基硅烷(AMS)，对(MCM－41)全硅介孔分子筛一步进行氨基官能团化和甲基疏水性修饰，然后将双水杨醛缩乙二胺合钴(Cosalen)通过氨基的轴向配位固载在修饰后的载体MCM－41上。X射线衍射和N2物理吸附/脱附的结果表明经过AMS双功能硅烷化修饰以及固载Cosalen后载体的孔道结构保持良好。考察了硅烷试剂用量对硅烷化效率的影响，结果表明当AMS的加入量为4.00mmol/g时，甲基修饰量达到1.95mmol/g；水和环己烷的静态吸附结果表明硅烷化修饰后，催化剂载体的疏水性明显增强。制得的催化剂应用于环己烷的分子氧氧化反应，130℃反应2h，环己烷转化率达到7.2%，环己醇和环己酮总选择性达到70.5%，较未经AMS修饰的催化剂Cosalen/MCM－41获得的醇酮总选择性提高了13%。
