Abstract

The invention discloses a preparation method of a 5-methyltetrazole energetic metal coordination compound, which belongs to the technical field of preparation of energetic metal coordination compounds. The preparation method is to dissolve methyl tetrazole in distilled water and add nitric acid Salt, after stirring for 30 minutes, put it into a reaction kettle with a polytetrafluoroethylene liner, react at a constant temperature of 120±1°C for 72h, then lower it to 80°C and keep it for 12h, and then lower it to room temperature at a rate of 3°C / h. The target coordination compound is obtained, and the coordination compound has good detonation heat and thermal stability, and low mechanical sensitivity, and the invention can prepare a product with high purity and high yield through a green and environment-friendly method.

Description

technical field [0001] The invention relates to the technical field of preparation of energetic metal coordination compounds, in particular to a preparation method of 5-methyltetrazole energetic metal coordination compounds. Background technique [0002] Energetic materials include explosives, propellants and pyrotechnics, etc., which are widely used in various fields, such as: aerospace propellants, mining engineering, pyrotechnics manufacturing, etc. With the increasingly widespread application of energetic materials, the requirements for them are also constantly changing, and have gradually evolved from the pursuit of high energy to the pursuit of "safety, green, high energy, and high density". Due to the advantages of high density, good thermal stability, excellent mechanical strength and hardness, energetic metal complexes can better meet the requirements of high energy and insensitivity, and will become a new generation of energetic materials. According to comprehensi...
