摘要：研究了四价钒配合物VO(pic)2·H2O及其分子筛负载型催化剂VO(pic)2-NaY对芳香烃和正构烷烃的催化氧化性能.实验结果证明,VO(pic)2-NaY催化剂具有与VO(pic)2·H2O配合物催化剂相似的催化氧化活性,而且使对位产物(芳香烃为底物)和伯醇(底物为正构烷烃)的选择性得到提高,显示出均相配合物催化剂所不具有的择形选择性.
Zeoliteencapsulated vanadium(Ⅳ) picolinic complexes catalyst and corresponding homogeneous catalyst VO(pic)2·H2O were prepared. The catalysts were used in the oxidation of toluene, nhexane and nheptane with CO(NH\-2)2·H2O\-2 as oxidant under 308 K. The results suggested that the 'shipinabottle' catalyst retains the same catalytic activity as homogeneous catalyst VO(pic)2·H2O and exhibits good shape selectivity as compared to the unencapsulated complexes.
