New catalysts for the highly efficient combustion of solid rocket motorpropellant

摘要

A large number of ferrocene derivatives have been reported as burning rate (BR) catalysts on the thermal decomposition of Ammonium Perchlorate (AP) due to the fact has a close relationship with the combustion process of the composite solid propellants. Within these series the binuclear complexes have better performances than the mononuclear derivatives. Our research group has prepared bimetallic compounds derived from p-phenylene, due to the fact that these types of complexes have a very high molecular weight, one of the keys to overcome the problem of migration and sublimation[l]. On the other hand, bimetallic complexes are often precursors of mixed-valence species. The chemical oxidation of a bimetallic compound generate an ionic mono-oxidized compound, therefore, from this point of view, the mixed-valence compound will contribute also to prepare the ionic compounds which exhibited a low migration tendency compared with the neutral BR catalysts reported [2].
