钴离子交换 SAPO-5分子筛催化空气氧化苯甲醇制苯甲醛

摘要

Co-SAPO-5 was prepared by a simple ion-exchange route and firstly applied in the aerobic epoxidation of benzyl alcohol, which exhibited high activities to achieve benzyl alcohol conversion of 82.5%with benzaldehyde selectivity of 64 .3%.Recycling research results investigated the good recyclability and stability of Co-SAPO-5 as heterogeneous catalysts.%探索过渡金属离子交换分子筛催化空气氧化苯甲醇制苯甲醛的绿色、多相催化反应体系．研究结果表明，Co-SAPO-5在催化空气氧化苯甲醇制苯甲醛的反应中表现出优异的催化活性，苯甲醇的转化率为82．5％，苯甲醛的选择性为64．3％．循环使用实验表明此催化剂是稳定的、可多次重复使用的多相催化剂．
