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
二茂铁燃速催化剂(BRC)因其催化性能高而成为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BRCs,并通过UV-Vis、NMR、HRMS和IR光谱对其结构进行了表征。通过
DSC和TG研究了这些
二茂铁嗪对AP热降解的催化作用。结果证实,没有
二茂铁基
丙烷的吖嗪的催化性能不如卡茂(Cat),而吖嗪与双二茂基
丙烷的催化性能与 Cat 相当。抗迁移研究表明,单核
二茂铁和 Cat 均表现出迁移性,而多核
二茂铁在长期储存后不迁移。因此,多核
二茂铁是一种具有应用前景的新型高效、非迁移性BRC。
