Embodiment Construction

[0014] The present invention is realized through the following examples, but the conditions and results described in the implementation do not limit the content and rights of the invention.

[0015] Typical preparation method:

[0016] Weigh Htza (0.0768 g, 0.6 mmol) and dissolve it in 10 mL of acetonitrile solution, and add 10 mL of 0.01 mmol L dropwise to it -1 Ce(NO 3 ) 3 Acetonitrile solution. The mixed solution was stirred at room temperature for 1 hour and filtered, and the filtrate was left standing at room temperature. After 2 days, colorless cuboid crystals were precipitated.

[0017] Structure Characterization:

[0018] The chemical formula of the synthesized complex is known from elemental and single crystal structure analysis: [Ce(tza)(NO 3 ) 2 (H 2 O) 3 ] n , belongs to the orthorhombic crystal system, P 2 1 2 1 2 1 space group. Its asymmetric structural unit contains a crystallographically independent Ce( ) atom, a tza - Ligand, two NO 3 - a...

Abstract

The invention relates to the field of cerium energetic complex preparation and application. The cerium tetrazole acetate energetic complex is prepared in a normal-temperature acetonitrile solvent, a composition of the complex is [Ce(tza)(NO3)2(H2O)3]n, and the complex belongs to an orthorhombic system and a P 21 21 21 space group. The complex has an evident promoting effect on thermal decomposition of HMX which is a main component of NEPE (nitrate ester plasticized polyether) propellant, and the complex can hopefully serve as a potential energetic combustion accelerant in the propellant.

Description

technical field [0001] The invention relates to the field of preparation and application of cerium-containing energetic complexes, specifically, the preparation and application of cerium complexes formed by cerium ions and tetrazoleacetic acid. Background technique [0002] The adjustment of propellant combustion performance is one of the core technologies of propellant application research. The burning rate pressure index is one of the important indicators to measure the combustion stability of the propellant. It is generally required that the propellant has the combustion characteristics of a wide range of burning rate adjustment and a low pressure index. At present, researchers generally use the addition of combustion accelerators or combustion catalysts to adjust the burning rate and reduce the pressure index. The dosage is small and the effect is remarkable. It is an important functional material in solid propellants. Due to the diversity of solid propellant formulatio...
