To comprehend the synergistic catalytic effect on the thermal decomposition of ammonium perchlorate (AP) when two ferrocene (Fc) fragments are in the same molecule linked by the ligand 4,4'-(1,4-phenylenebis(1H-1,2,3)-triazol-4,1-diyl))diphenol (1) was synthesized a bimetallic ferrocene compound (2), and compared with other homo- and monobimetallic ferrocene compounds already reported, as a potential burning rate catalyst. We conducted a differential scanning calorimetry (DSC) analysis of compound (2), which showed a decrease the high-temperature decomposition (HTD) of Ammonium Perchlorate (AP) to 379 ºC. Our results suggest that the ferrocene is a suitable and competitive alternative to be used as an enhancer of solid composite propellants.
