摘 要:为了阐明芳香族金属盐配合物作为燃烧催化剂时配体结构与其催化性能的关系,分别从单环芳香族配体中基团的数量与位置两方面总结了其对催化性能的影响规律。根据其配体的不同,总结了含羟基、氨基、硝基的芳香族金属盐的催化效果,并分析了每种基团的数量及位置对催化性能的影响。发现芳香族配合物中苯环上羟基的数量越多,对双基系推进剂催化效果越好。对于含氨基的芳香族配体,苯环上各位置取代基团的活性大小顺序为:邻位>对位>间位。对于苯环上含硝基的配合物而言,在一定范围内苯环上取代基团的位置相对于取代基团的数量来说,对催化剂的催化活性影响更大。基于上述结论,提出了单环芳香族金属盐配合物作为燃烧催化剂的选择依据。附参考文献57篇。In order to evaluate the relationship between the ligand structure and catalytic performance of metal aromatic complexes used as combustion catalysts, the influence of ligand number and position on the catalytic performance were reviewed.The catalytic effects of complexes containing hydroxyl, amino and nitro groups were analyzed and the influences of their number and positions on the catalytic performances were also discussed.It is found that, the more the hydroxyl groups on the benzene ring of aromatic complex, the better the catalytic effects would be.For the complexes containing amino groups, their catalytic activities for propellant combustion are closely related to the positions of amino groups and the activities are in the order of ortho>parallel>meta.As for the complexes containing nitro groups, however, the location of substituted group has a greater influence on the catalytic activity than the number of groups.How to choose metal monocyclic aromatic complexes as highly efficient combustion catalysts was also proposed.57 References are attached.
