Embodiment 1

[0028] A method and device for synthesizing copper azide, the reaction device includes a heat-collecting magnetic stirrer 1, a three-necked flask 2, a thermometer (3), a right-angle elbow 4, a drying tube 5, and an "S" type Glass elbow 6, explosion-proof ball 7, anti-suckback ball 8, beaker 9 and nitrogen bottle 10. Silicone oil is used in the heat-collecting magnetic stirrer 1 oil bath; anhydrous calcium chloride desiccant is housed in the drying tube 5; KOH solution is filled in the beaker 9, and excess azide gas is recovered ; The reaction needs to be carried out under fume hood and effective protection. Copper azide synthesis process of the present invention is:

[0029] (1) Fix a 250mL round-bottomed three-necked flask in an oil bath with an iron stand, and add two-thirds of the volume of silicone oil to the oil bath; add a rotor and sodium azide (0.5g) to the three-necked flask and stearic acid (2.75g), add anhydrous calcium chloride to the drying tube and plug both en...

Abstract

The invention discloses a method and a device for synthesizing copper azide, in order to solve the problem of high danger in synthesis of copper azide and provide a new technology and a new technique for preparation of a novel green initiating explosive. A reaction device comprises an azoimide generation device, an azidation device and a tail gas absorption device. The method and the device for synthesizing the copper azide initiating explosive have the following remarkable advantages: (1) since explosion happens very easily once azoimide gas is in contact with grease, water and the like, and the whole device is all formed by means of connecting glassware through ground openings without rubber tubes and grease type substances such as vaseline, the safety of reaction is guaranteed fundamentally; (2) the azoimide gas is fed in from the lower part and discharged out from the upper part, thereby fully reacting with porous copper; (3) an anti-explosion ball is smart is structure design and samples can be conveniently placed in and taken out; (4) the gas absorption device with an anti-back-suction ball is capable of effectively preventing the azoimide gas from escaping.

Description

technical field [0001] The invention relates to a method for synthesizing green primer, in particular to a method and device for synthesizing copper azide. Background technique [0002] The key components of widely used primary explosives are lead sensitive compounds, such as lead azide, lead styphate, etc., which are harmful to the environment and affect human health. Cu has very little harm to the environment, and the use of copper to replace lead-containing agents commonly used in pyrotechnics meets the requirements of environmental protection. However, because the mechanical sensitivity of copper azide is higher than that of lead azide, it is almost explosive when touched, and it is very dangerous in the process of preparation and use, which limits its research and application. How to take advantage of the friendly characteristics of copper and the environment while taking into account the safety requirements of pyrotechnic agents is an urgent problem to be solved. [...
