Examples
Embodiment 1
[0026] At room temperature, add 100ml of ethanol into the three-necked flask, then add a sufficient amount of BTF under stirring, control the temperature at 25°C, dissolve, and filter to obtain a saturated solution of BTF. Then add a sufficient amount of DNB, stir, dissolve, and filter, and the resulting filtrate is a BTF-DNB saturated solution. Put the filtrate in a beaker, then put it still in a thermostat at 30°C, let the solvent evaporate, precipitate crystals, and dry to obtain BTF-DNB eutectic explosive.
Embodiment 2
[0028] At room temperature, add 90ml of methanol into the three-necked flask, then add enough BTF under stirring, raise the temperature to 30°C, dissolve and filter to obtain a saturated solution of BTF. Then add a sufficient amount of DNB, stir, dissolve, and filter, and the resulting filtrate is a BTF-DNB saturated solution. Put the filtrate in a beaker, then put it still in a constant temperature box at 25°C, let the solvent evaporate and precipitate crystals. Dry to obtain BTF-DNB eutectic explosive.
Embodiment 3
[0030] At room temperature, 50ml of acetone was added into the three-necked flask, and then a sufficient amount of BTF was added under stirring, the temperature was controlled at 20°C, dissolved, and filtered to obtain a saturated solution of BTF. Then add a sufficient amount of DNB, stir, dissolve, and filter, and the resulting filtrate is a BTF-DNB saturated solution. Put the filtrate in a beaker, then put it still in a thermostat at 30°C, let the solvent evaporate, precipitate crystals, and dry to obtain BTF-DNB eutectic explosive.
