Abstract

In this Project we propose the synthesis as well as a full characterization of the homo- and heterobimetallic complexes ferrocene-type with potential applications as burning rate catalysts in solid propellants.

A large number of ferrocene derivatives have been reported as burning rate catalysts on the thermal decomposition of AP, which has a close relationship with the combustion process of the propellants. These data show that the ferrocene derivatives have superior burning rates, compared with others BR catalysts such as Fe2O3, and within these series the binuclear complexes have better performances than the mononuclear derivatives, thereby improving the performance of the composite solid propellants.

Although ferrocene derivatives BR catalysts have extraordinary effects in the enhancement of the burning rates of composite solid propellant, they have some disadvantages such as sublime during curing and processing, and migrate to the surface on the propellants after prolong storage times. These shortcomings can destruct the steady combustion of the propellants and in some cases result in danger when mixing with ultrafine AP, because are sensitive to electrostatic discharge, which is very dangerous and even leads to an explosion in the fabrication of propellants.

In this context, novel homo- and heterobimetallic complexes ferrocene-type compounds offer a unique opportunity to study their catalytic properties on the thermal decomposition of AP , due to use of semi-rigid bridged ligands and rigid ligand proposed in this project as well as the high molecular weight of these derivatives it is expected that they will have low migration and sublimation loss upon curing and under storage. Therefore, this project aims on the one hand to obtain new catalysts highly efficient combustion and on the other overcome the disadvantages generated by the migration of those to date reported.
