Description
Technical field
The present invention relates to a kind of energetic materials, and in particular to a kind of two (1,5- nitre aminotetrazoles)-four hydration cobalt potassium
Close object.
Background technique
Priming is most sensitive chemical energy source, has the characteristics that high sensitivity, high-voltage instant, high-power, when by the external world compared with
When small initial punching can be such as shock, friction, needle thorn, flame equal excitation, detonation can be generated and cause secondary charging explosion.Currently,
In dual-use field, widely used priming is lead azide and lead styphnate, is had since both primings contain
Malicious heavy metal element --- lead causes to cause seriously to pollute to personnel and environment using such priming, as people are to weapon
The performance deficiency of the raising of ammumtion safety and environmental quality requirement, lead azide and lead styphnate leads to priming system and medicament
Major accident occurs in duties processing and use, also counteracts the development of priming system, therefore, various countries' researcher is all positive
Carry out the research work of Novel detonating medicine, desired design goes out to prepare safety, sensitivity is suitable for rising with a new generation of high energy output, environment-friendly type
Quick-fried drug kind.High nitrogen tetrazole derivatives structure contains a large amount of N-N and C-N key, with aromatic structure stability, have compared with
The features such as good thermal stability, higher positive generation heat and biggish gas production, and its decomposition product is predominantly cleaned without dirt
The nitrogen of dye has bright prospects in terms of constructing novel environment-friendly priming.5- nitro tetrazolium has chemical potential height, energy
The features such as density is big, high nitrogen, low-carbon hydrogen content are easy to reach oxygen balance, are a kind of potential energetic material ligands of tool, wherein
It is a kind of novel green, environment-friendly type that preparation is designed based on 5- nitro tetrazolium that four (5- nitro tetrazolium) two hydrated irons (II), which change sodium,
Priming.
Zhu Yahong etc. " synthesis and characteristic that environmentally friendly four (5- nitro tetrazolium) two hydrated irons (II) of priming change sodium ", contains energy
Material, 2012,20 (6), 726-730 disclose the molecular structure that four (5- nitro tetrazolium) two hydrated irons (II) change sodium compound
