Embodiment 1

[0017] Turn on the water bath to raise the temperature to 50-55°C, add 0.0034mol of 5,5'-azotetrazole sodium solution into the compounder and start stirring, put it in the water bath as the bottom solution, and dissolve 0.0034mol of copper sulfate in an appropriate amount of Heat and dissolve in distilled water in the same water bath. When the temperature in the compounder reaches 50-55°C, quickly add 2ml of 25-28% ammonia water, and pour copper sulfate solution into it for compound reaction after 1 minute. Continue to react for 5 minutes after the feeding is completed; then water-cool the compounder, and the temperature of the feed liquid drops below 40°C, then carry out discharge, suction filtration, water washing twice, ethanol dehydration twice, and drying at 40°C for 4 hours to finally obtain Green granular finished product with a yield of 95.5%.

Embodiment 2

[0019] Turn on the water bath to raise the temperature to 50-55°C, add 0.0034mol of 5,5'-azotetrazole sodium solution into the compounder and start stirring, put it in the water bath as the bottom solution, and dissolve 0.0037mol of copper sulfate in an appropriate amount of Heat and dissolve in distilled water in the same water bath. When the temperature in the compounder reaches 50-55°C, quickly add 2ml of 25-28% ammonia water, and pour copper sulfate solution into it for compound reaction after 1 minute. Continue to react for 10 minutes after the feeding is completed; then water-cool the compounder, and the temperature of the feed liquid drops below 40°C, that is, discharge, suction filter, wash with water twice, dehydrate with ethanol twice, and dry at 40°C for 4 hours to finally get Green granular finished product with a yield of 96.3%.

Embodiment 3

[0021] Turn on the water bath to raise the temperature to 50-55°C, add 0.0034mol of 5,5'-azotetrazolium sodium solution into the compounder and start stirring, put it in the water bath as the bottom solution, and dissolve 0.0041mol of copper sulfate in an appropriate amount of Heat and dissolve in distilled water in the same water bath. When the temperature in the compounder reaches 50-55°C, quickly add 2ml of 25-28% ammonia water, and pour copper sulfate solution into the compound reaction after 2 minutes. Continue to react for 5 minutes after the feeding is completed; then water-cool the compounder, and the temperature of the feed liquid drops below 40°C, then carry out discharge, suction filtration, water washing twice, ethanol dehydration twice, and drying at 40°C for 4 hours to finally obtain Green granular finished product with a yield of 95.1%.

Abstract

The invention discloses a method for preparing green primary explosive Cu(NH3)4ATZ.2H2O. The preparation method comprises that 5-aminotetrazole as an initial raw material is oxidized into sodium 5,5'-azotetrazolate by a basic oxidation method, ammonium hydroxide is added into the sodium 5,5'-azotetrazolate as a base solution at an appropriate temperature, a copper sulphate solution is fast added into the solution, the mixed solution undergoes a combination reaction, the reaction product is subjected to temperature keeping, cooling and suction filtration, and the filter residue is washed by water, then is dehydrated by ethanol and then is dried so that Cu(NH3)4ATZ.2H2O is obtained. The preparation method has simple and safe processes and short synthesis time, adopts low-toxicity or toxicity-less raw materials and has a low cost. After explosion decomposition of Cu(NH3)4ATZ.2H2O, a small amount of black residue is obtained and the gas product mainly comprises nitrogen so that environmental pollution is avoided. Cu(NH3)4ATZ as a dehydrated product of Cu(NH3)4ATZ.2H2O has good explosion performances and is a green primary explosive.

Description

technical field [0001] The invention belongs to a preparation method relating to a primer, in particular to a Cu(NH 3 ) 4 ATZ·2H 2 O preparation method. Background technique [0002] The commonly used primary explosives are lead azide (LA), lead styphenate (LTNR), dinitrodiazophenol (DDNP) and cadmium perchlorate carbohydrazide (GTG). Most of these primers contain toxic heavy metals, such as lead and cadmium; With the enhancement of people's awareness of environmental protection, these agents are increasingly unable to meet the needs of production and use, and more and more researchers have begun to turn their attention to the research of green pyrotechnic agents. The so-called green primer must not contain toxic metals and perchloric acid, and at the same time, have the characteristics of light resistance, non-hygroscopicity, thermal stability, chemical stability, and moderate sensitivity. [0003] In China, Xie Gang, Jiao Baojuan, etc. have synthesized a series of azo...
