Abstract

The invention discloses a ferrocenyl ruthenium metal cluster as well as a preparation method and an application thereof. The structural formula of the cluster is shown in the description, wherein R1 is not equal to R2, R3 is not equal to R4, only two of R1, R2, R3 and R4 are ferrocenyls, the other two are 2-thienylcarbonyl, 4-nitrobenzoyl, 4-aminobenzoyl or benzoyl, or one is 4-nitrobenzoyl and the other is 4-aminobenzoyl; or only two of R1, R2, R3 and R4 are ferrocenylformyl, and the other two are 2-thienyl, 4-nitrophenyl or phenyl. The mobility and volatility of the ferrocenyl ruthenium metal cluster as a combustion rate catalyst are reduced while the iron content is guaranteed, and the ferrocenyl ruthenium metal cluster has higher formation heat and combustion heat and has a better combustion catalysis effect on the thermolysis process of AP. The cluster is simple to prepare, has high catalytic activity and can remarkably increase the thermolysis temperature of AP and increase decomposition heat.

Description

technical field [0001] The invention belongs to the technical field of solid propellants, and in particular relates to a ferrocene ruthenium metal cluster compound and a preparation method and application thereof. Background technique [0002] Ferrocene and its derivatives, as the most important burning rate catalysts in solid propellants (especially composite propellants), have been widely used in strategic and tactical weapon systems. Due to the advantages of high iron content, good burning rate catalytic effect, high boiling point, good thermal stability, non-volatile and difficult migration, dual-nuclear ferrocene-based burning-rate catalysts have gradually replaced mononuclear ferrocene-based burning-rate catalysts. However, its shortcomings such as easy oxidation, low-temperature crystallization, and complex synthesis process have seriously affected the storage life of various missile propellant charges. Therefore, the development of multi-nuclear ferrocene-based burn...
