Abstract

The invention discloses an N-ferrocenylmethyl-3-amino-1,2,4-triazole energy-containing transition metal complex and a preparation method thereof. The structural formula of the complex is as shown in the description, wherein M represents Cu, Zn, Mn, Ni, Co, Cd or Fe, L is 1H, 1'H-(5,5'-bistetrazole)-1,1'-diol dianion, and x is an integer from 0 to 3. The complex disclosed by the invention is simplein preparation method, low in cost and high in yield and has better burning catalysis effect on main components (ammonium perchlorate and hexogen) of a composite solid propellant; the N-ferrocenylmethyl-3-amino-1,2,4-triazole ligand in the complex has high nitrogen content, has higher positive enthalpy of formation and has synergistic catalysis effect with transition metal ions; and by addition of energy-containing compound 1,1'-dihydroxy-5,5'-bistetrazole disodium salt tetrahydrate, the sensitivity of a burning rate catalyst can be reduced, the energy can be supplied for the solid propellant, and the decomposed and released nitrogen gas is friendly to the environment.

Description

technical field [0001] The invention belongs to the technical field of solid propellants, and in particular relates to a class of N-ferrocenylmethyl-3-amino-1,2,4-triazole energetic transition metal complexes and a preparation method of the complexes. Background technique [0002] With the development of modern defense technology, many countries have shown increasing interest in improving the performance of tactical missiles (including improving the range, maneuverability and flight speed of missiles), which puts forward more and more requirements for the energy of engines and propellants. Come higher demands. Regardless of the miniaturization, mobile launch, concealment, low cost and low-level maintenance requirements of strategic missiles, or the signal and penetration of tactical missiles, environment, mobility (thrust adjustment), increased range, vulnerability requirements, and aerospace The requirements of high energy and "cleanness" in the field make the research on ...
