Аннотация:For overcoming the migration problems of ferrocene (Fc)-based burning rate catalysts (BRCs) as well as for enhancing burning rate (BR) of ammonium perchlorate (AP)-based propellants, ferrocenylated-amino pyridines (AP-Fcs) and ferrocenylated-amino thiazoles (AT-Fcs) have been synthesized. The synthesis of AP-Fcs and AT-Fcs was confirmed by nuclear magnetic resonance (1H NMR). Electrochemical properties of these ferrocenylated derivatives were explored by cyclic voltammetry (CV). The BR catalytic activities of AP-Fcs and AT-Fcs on thermal decomposition of AP were examined by thermogravimetric (TG) and differential thermogravimetric (DTG) techniques. Thermal analysis results showed that AP-Fcs and AT-Fcs showed good BR catalytic effects on thermal decomposition of AP. AP-Fcs and AT-Fcs were also applied for anti-migration studies in comparison with catocene (Cat) and ferrocene. It was found that AP-Fcs and AT-Fcs displayed anti-migratory behavior.
