Abstract
在低模板剂浓度和弱碱介质中合成催化材料Si-MCM-41、Sn-MCM-41, 并用XRD、N 2 物理吸附-脱附、FT-IR、ICP-AES和TEM等手段对催化材料进行了表征. 研究了合成方法对制备Sn掺杂MCM-41介孔分子筛的影响, 结果表明: 水热晶化法(DHT)合成的Sn-MCM-41, Sn物种主要进入分子筛的骨架中; 而模板离子交换法(TIE)合成的Sn-MCM-41, Sn物种主要位于分子筛的表面. Sn-MCM-41介孔分子筛催化环己酮Baeyer-Villiger氧化反应结果表明, n (H 2 O 2 ): n (酮)＝3:1, 30g1,4-二氧六环为溶剂, H 2 O 2 为氧源, 70℃反应6 h, 环己酮的转化率可达40.02%, e-己内酯的选择性为45.69%.
