Description

Technical Field

[0001] This invention relates to the field of energetic materials technology, and in particular to a safe disposal method for the green detonator ICM-103. Background Technology

[0002] ICM-103, or 4-azido-5-nitro-7H-pyrazolo[3,4-d][1,2,3]triazine-2-oxide, is a novel high-performance, green organic initiating explosive. It was first reported in Chinese patent CN108752349A in 2018, and further reported in the 2019 academic paper "A green metal-free fused-ring initiating substance" (DOI: 10.1038 / s41467-019-09347-y) and the 2020 doctoral dissertation "Design, Synthesis and Performance Study of Novel Binary Fused-Ring Energetic Molecules Based on the Pyrazolo[1,2,3]triazine-2-oxide Skeleton." Due to its simple preparation, green and pollution-free nature, metal-free composition, reliable ignition, chemical stability, and strong initiation performance, ICM-103 has attracted widespread attention both domestically and internationally.

[0003] During laboratory synthesis, pilot-scale production, large-scale industrial production, testing and inspection, and performance evaluation, a certain amount of residual ICM-103 will be generated. Since ICM-103 is a high-powered detonating explosive, it is necessary to destroy it promptly to avoid casualties. Currently, due to the sensitive nature of detonating explosives, explosive destruction is commonly used for disposal. For small quantities of detonating explosives, chemical decomposition can also be used.

[0004] However, explosive disposal methods can generate explosive shock waves and loud noises, requiring a high level of specialization and expertise. Although usually operated remotely, they still carry a high risk of accidents. Chemical decomposition disposal methods require specialized equipment and chemical reagents, and generate a certain amount of wastewater, resulting in high post-treatment costs and time consumption. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a safe disposal method for the green detonator ICM-103.

[0006] In a first aspect, the present invention provides a safe disposal method for the green detonator ICM-103.

[0007] The safe disposal method includes: doping the green detonator ICM-103 with metal ions or impregnating it with an alcohol solvent, and then igniting and incinerating it for disposal.

[0008] ICM-103 is a CHON-based organic initiating explosive, containing no metal components, with a nitrogen content as high as 56.5%, and an oxygen balance of -10.75% (calculated as CO). 99.7% of its explosive decomposition products are nitrogen (N2, 51.3%), carbon dioxide (CO2, 9.2%), carbon monoxide (CO, 7.5%), water vapor (H2O, 2.9%), formic acid (CH2O2, 2.6%), and amorphous carbon (C, 26.2%). Therefore, incineration is a green and economical method of destruction. However, initiating explosives typically explode immediately after ignition, making incineration a difficult method to destroy.

[0009] Regarding doped metal ions

[0010] The invention unexpectedly discovered that doping the green detonator ICM-103 with metal ions can actually suppress its detonation performance, making incineration and destruction possible.

[0011] It should be noted that the doping described in this invention refers to doping at the molecular level, not physical mixing, i.e., in the case of the detonator ICM-103. The structure is connected to the metal ion through chemical bonds.

[0012] In some embodiments of the present invention, the metal ions may be potassium ions, lithium ions, sodium ions, magnesium ions, calcium ions, aluminum ions, etc.

[0013] It is generally believed in the art that a metal salt of an initiating explosive can also be used as an initiating explosive. However, in this invention, it has been tested that the metal salt of the initiating explosive ICM-103 does not have initiating properties, so the initiating explosive ICM-103 can be converted into its metal salt before being incinerated and destroyed.

[0014] In some embodiments of the present invention, potassium ion doping is achieved by reacting the green initiator ICM-103 with metal hydroxides, metal carbonates or metal bicarbonates.

[0015] Furthermore, the molar ratio of the green initiating explosive ICM-103 to the metal hydroxide is 1:(1-4), and the reaction temperature is -10℃ to 80℃. The metal hydroxide can be potassium hydroxide, lithium hydroxide, sodium hydroxide, magnesium hydroxide, calcium hydroxide, aluminum hydroxide, etc.

[0016] Furthermore, the molar ratio of the green initiating explosive ICM-103 to the metal carbonate is 1:(0.7-5), and the reaction temperature is 20℃-80℃. The metal carbonate can be potassium carbonate, lithium carbonate, sodium carbonate, magnesium carbonate, aluminum carbonate, etc.

[0017] Furthermore, the molar ratio of the green initiating explosive ICM-103 to the metal bicarbonate is 1:(1.2-4), and the reaction temperature is 20℃-80℃. The metal bicarbonate can be potassium bicarbonate, lithium bicarbonate, sodium bicarbonate, magnesium bicarbonate, calcium bicarbonate, aluminum bicarbonate, etc.

[0018] Regarding the use of alcohol solvents for impregnation

[0019] Besides doping the green initiating explosive ICM-103 with metal ions, this invention also unexpectedly discovered that after dissolving ICM-103 in an alcohol solvent for a certain period of time, the resulting substance lacks initiation properties. The inventors speculate that this may be because after ICM-103 is wetted in an alcohol solvent, the azide groups undergo a transformation to amino groups, which blocks the combustion-to-detonation process, causing it to lose its initiation properties. Therefore, after ignition, it exhibits combustion rather than an explosion.

[0020] In some embodiments of the present invention, the alcohol solvent is selected from those with the general chemical formula C. a H b O c A liquid saturated alcohol or unsaturated alcohol, wherein a, b, and c are all positive integers and 1 < c ≤ a. Examples include ethanol, propanol, and butanol.

[0021] In some embodiments of the present invention, the volume concentration of the alcohol solvent is 75% to 100%, and the ratio of the green initiating explosive ICM-103 to the alcohol solvent is 1g:1 to 2mL. Excessive use of the alcohol solvent may result in excessive heat release after ignition, potentially posing an explosion hazard.

[0022] In some embodiments of the present invention, the immersion time of the alcohol solvent is 1 to 2 minutes.

[0023] In some embodiments of the present invention, the ignition is performed remotely using an electric igniter.

[0024] This invention employs an electric igniter for remote control ignition, making it safer and more controllable. Preferably, the electric ignition current is not less than 5A, and the ignition time is not less than 1s.

[0025] Secondly, the present invention provides a safe disposal device for green initiating explosive ICM-103, including an explosion-proof chamber equipped with an explosion-proof door and an explosion-proof observation window, wherein an explosive placement point is provided in the middle of the explosion-proof chamber, and an electric igniter is provided outside the explosion-proof chamber. The electric igniter is connected to an ignition head through a safety lead, and the ignition head contacts the initiating explosive ICM-103 to be ignited.

[0026] The safe disposal device provided by this invention can meet the safe disposal requirements of the green detonator ICM-103, and is applicable to both cases of doping with metal ions and impregnation with alcohol solvents. Specifically, if metal ion doping is used, the doped agent is placed in the middle of the explosion-proof chamber after doping is completed; if alcohol solvent impregnation is used, the detonator ICM-103 is first placed in the middle of the explosion-proof chamber, then the alcohol solvent is sprayed, and ignition is performed after sufficient impregnation time.

[0027] It is worth noting that, as an initiating explosive, the amount of ICM-103 that can be destroyed in a single operation is related to the size of the equipment space and the blast resistance level of the building, with an upper limit of approximately 70% of the maximum design capacity of the destruction device. However, to ensure sufficient safety, the common practice is to minimize the amount destroyed in a single operation and conduct multiple small-scale operations, provided that the destruction task can be completed on schedule.

[0028] This invention provides a safe disposal method for the green initiating explosive ICM-103. By first doping the green initiating explosive ICM-103 with metal ions or impregnating it with an alcohol solvent, the resulting new material lacks explosive properties and can be disposed of by incineration. Compared to traditional explosive and chemical decomposition methods, this method is simple, safe, economical, and environmentally friendly. Overall, it does not generate an explosive shock wave or a loud noise, requires no additional specialized chemical reagents or wastewater treatment, and the combustion products are non-toxic and harmless. This simple and efficient method effectively solves the problem of safe disposal of ICM-103 initiating explosives. Attached Figure Description
