Embodiment 1

[0022] At 20°C, add 10ml of 5% nitric acid aqueous solution into a three-necked flask, then heat a sufficient amount of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide under stirring to dissolve , and filtered to obtain a saturated aqueous solution of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide in nitric acid. Put the filtrate in a beaker, then put it still in a thermostat at 25°C, let the solvent evaporate, precipitate crystals, and dry to obtain 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid Self-assembled energetic crystals, the structure of which is attached figure 1 shown.

Embodiment 2

[0024] At 20°C, add 10ml of 30% nitric acid aqueous solution into a three-necked flask, then heat a sufficient amount of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide under stirring to dissolve , and filtered to obtain a saturated aqueous solution of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide in nitric acid. Put the filtrate in a beaker, then put it still in a thermostat at 25°C, let the solvent evaporate, precipitate crystals, and dry to obtain 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid Self-assembled energetic crystals.

Embodiment 3

[0026] At 20°C, add 10ml of 60% nitric acid aqueous solution into a three-necked flask, then heat a sufficient amount of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide under stirring to dissolve , and filtered to obtain a saturated aqueous solution of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide in nitric acid. Put the filtrate in a beaker, then put it still in a thermostat at 35°C, let the solvent evaporate, precipitate crystals, and dry to obtain 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid Self-assembled energetic crystals.

Abstract

The invention discloses a preparation method of a 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid self-assembled energetic crystal material, comprising the following steps: (1) preparinga saturated aqueous solution of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide; (2) putting the saturated aqueous solution of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide in a beaker, then standing in aconstant temperature incubator, evaporating a solvent, and carrying out formation of crystal nuclei, crystal growth, crystal formation, filtration and drying in sequence to obtain 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid self-assembled energetic crystal. The invention innovatively provides a 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid self-assembled energeticcrystal material.

Description

technical field [0001] The invention belongs to the field of energetic materials, and specifically relates to self-assembled energetic crystal materials of 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and nitric acid and a preparation method thereof. Explosives have good application prospects. Background technique [0002] Energetic materials are a class of compounds or mixtures composed of oxidants and combustibles that can independently undergo redox chemical reactions and output energy. In traditional energetic compounds such as hexanitrohexaazaisowurtzitane (CL-20) and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane ( In the construction of HMX), oxidants (such as nitro) and combustible components (such as -CH 2 -skeleton) components are usually integrated in one molecule. But the intrinsic incompatibility of oxidants and combustible components makes the integration of oxidants and combustibles in one molecule very difficult. Typically, an increase in the energy of an...
