Synthesis and Anti-migration Studies of Ferrocene-Based Amides as Burning Rate Catalysts

To overcome the migration problems of burning rate catalysts (BRCs), ferrocene-based amide compounds (AM-Fcs) were synthesized. The successful synthesis of AM-Fcs were confirmed by proton nuclear magnetic resonance, and Fourier transform infrared spectroscopy. The electrochemistry behaviors of AM-Fcs were examined by cyclic voltammetry (CV). The CV experimental results indicated that these AM-Fcs showed good electrochemical performances, which were contributable to their burning rate (BR) catalytic activity in composite solid propellants. The anti-migration test of AM-Fcs verified significantly slower migration than ferrocene and the most commonly used BRCs catocene. Thermal stability and BR catalytic impact of AM-Fcs on the thermal decomposition of ammonium perchlorate (AP) were studied by thermogravimetry and differential thermogravimetry. These AM-Fcs revealed good catalytic behaviors on the thermal degradation of AP.

Automated summary

A new class of ferrocene-based amide compounds (AM-Fcs) was synthesized and characterized in this study. The AM-Fcs demonstrated good electrochemical properties and catalytic activity for burning rate in solid propellants. Additionally, they showed potential application in anti-migration and thermal decomposition studies.
