Embodiment 1

[0033] At 20°C, add 40ml of acetone into the three-necked flask, then add 0.438g of CL-20 and 0.172g of MDNI under stirring, when CL-20 and MDNI are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.10Mpa, open the valve, the co-crystal solution forms a thin stream through the nozzle, sprays it into the collection tank filled with non-solvent water, precipitates crystals, filters, and dries to obtain CL-20 / MDNI eutectic explosive.

Embodiment 2

[0035] At 25°C, add 30ml of acetone into the three-necked flask, then add 0.438g of CL-20 and 0.158g of DNI under stirring, when CL-20 and DNI are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.15Mpa, open the valve, the co-crystal solution forms a thin stream through the nozzle, sprays it into the collection tank filled with non-solvent water, precipitates crystals, filters, and dries to obtain CL-20 / DNI eutectic explosive.

Embodiment 3

[0037] At 40°C, add 40ml of acetonitrile into a three-necked flask, then add 0.438g of CL-20 and 0.172g of MDNI under stirring, when CL-20 and MTNP are completely dissolved, filter to obtain a co-crystal solution. Put the co-crystal solution in the spray tank, then adjust the spray pressure to 0.20Mpa, open the valve, the co-crystal solution forms a thin stream through the nozzle, sprays it into the collection tank filled with non-solvent water, precipitates crystals, filters, and dries to obtain CL-20 / MDNI eutectic explosive.

Abstract

The invention discloses a preparation method of a hexanitrohexaazaisowurtzitane (CL-20) and imidazole cocrystallized explosive. The preparation method comprises the following steps: 1, preparing a CL-20 and imidazole cocrystallization solution; 2, preparing a CL-20/imidazole cocrystallized explosive. The invention further aims to provide the hexanitrohexaazaisowurtzitane (CL-20) and imidazole cocrystallized explosive, which is prepared according to the preparation method of the hexanitrohexaazaisowurtzitane (CL-20) and imidazole cocrystallized explosive. A CL-20/MDNI and CL-20/MDNI eutectic crystal has high energy density and high safety, can serve as a main explosive, and has good application prospect in the field of energetic materials. The preparation method provided by the invention is simple in process flow, convenient to operate, mild in condition and easy in amplified preparation, and provides an effective method for synthesis of a novel energetic material.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to a preparation method of hexanitrohexaazaisowurtzitane (CL-20) and imidazole eutectic explosive. Background technique [0002] Explosives requiring high energy have always been one of the hotspots and difficulties in the field of energetic materials research at home and abroad. At present, people mainly use traditional design and synthesis methods to obtain high-energy explosives. This traditional method has a complicated preparation process, a long cycle, and great difficulty. Even if a lot of manpower and material resources are spent, high-energy explosives cannot be obtained effectively. Therefore, it is urgent to study and explore new preparation methods and approaches. [0003] In recent years, the emergence and development of eutectic technology provides a new way to construct new energetic material molecules. With the help of eutectic technology, explosive mol...
