二茂铁燃速催化剂（BRC）具有较高的催化性能，是促进复合固体推进剂燃烧的常用催化剂，但该类催化剂存在易迁移的缺点。高氯酸铵（AP）是复合固体推进剂的主要氧化剂，其热降解行为对推进剂的燃烧有重要影响。合成了新的单核和多核二茂铁嗪类BRC化合物，并通过UV-Vis、NMR、HRMS和IR对其结构进行了表征。用DSC和TG研究了它们对AP热降解的催化作用。结果证实，没有双二茂铁基丙烷的吖嗪的催化性能劣于Catocene（Cat），而具有双二茂铁基丙烷的吖嗪的催化性能与Cat相当。抗迁移研究表明，单核二茂铁吖嗪和Cat都表现出迁移性，而多核二茂铁吖嗪在长期储存后不迁移。因此，多核二茂铁肼是一种具有应用前景的新型高效、无迁移的BRC。
Ferrocene burning rate catalyst (BRC) is a common catalyst to promote the combustion of composite solid propellant because of its high catalytic performance, but this kind of catalyst has the disadvantage of easy migration. Ammonia perchlorate (AP) is the main oxidant of composite solid propellant, and its thermal degradation behavior has an important impact on the combustion of propellant. New mononuclear and polynuclear ferroceneazine BRCs were synthesized, and their structures were characterized by UV-Vis, NMR, HRMS and IR spectra. The catalytic effects of these ferrocenylazines on the thermal degradation of AP were studied by DSC and TG. The results confirmed that the catalytic performance of azine without bisferrocenylpropane was inferior to that of Catocene (Cat), while the catalytic performance of azine with bisferrocenylpropane was equivalent to that of Cat. Anti-migration studies showed that both mononuclear ferroceneazines and Cat showed mobility, while polynuclear ferroceneazines did not migrate after long-term storage. Therefore, polynuclear ferroceneazine is a new kind of high-efficiency and non-migration BRC with application prospects.
