Abstract

The invention discloses a ferricinium ion type high-nitrogen metal complex and a preparation method thereof. The structural formula of the complex is as shown in the description; and in the formula, M represents any one of Mn<2+>, Co<2+>, Cu<2+>, Ni<2+> and Pb<2+>, X represents C or N, and L represents picrate or trinitroresorcin divalent anion, wherein n is equal to 2 when the L represents the picrate, and n is equal to 1 when L represents the trinitroresorcin divalent anion. Metal ions are introduced into the complex provided by the invention, so the anti-mobility of the complex is improved and the volatility of the complex is reduced; the introduced ligand and polynitrophenol anion have high formation heat and combustion heat, so the combustion catalyst performance of the complex on the thermal decomposition process of ammonium perchlorate is improved; and the preparation method of the complex provided by the invention is simple.

Description

technical field [0001] The invention belongs to the technical field of solid propellants, and in particular relates to a ferrocene ion-type high-nitrogen metal complex and a preparation method thereof. Background technique [0002] Ferrocene and its derivatives, because of their excellent combustion regulation function, have been widely used in strategic and tactical weapon systems as the most important burning rate catalysts of solid propellants (especially composite propellants). Ballistic missiles (including theater, short-range, medium-range, intercontinental ballistic missiles, etc.), airborne tactical missiles, anti-missile high-speed kinetic energy missiles and sea-based mines, torpedoes and other weapons play a huge role. [0003] Ferrocene-based burning rate catalysts have been widely used in solid propellants since the 1960s and 1970s. In a US patent published by Huskins in 1972, it was proposed that the allyl alcohol structure be introduced into ferrocene to prepa...
