Embodiment 1

[0034] Preparation of 1-nitronaphthalene / TNT co-crystal

[0035] 1. Accurately weigh 60.00 mg of 1-nitronaphthalene and 80.00 mg of TNT with an analytical balance.

[0036] 2. Pour the raw materials into a 50ml beaker, and use a 10ml pipette to accurately measure 10ml of methanol and pour it into the beaker.

[0037] 3. Put the magnetic stirring bar into the beaker, turn on the stirring, and put the beaker into a 40°C constant temperature water bath after the drug is completely dissolved. Afterwards, the solvent evaporated slowly, and long needle-shaped single crystals formed after 30 hours.

[0038] 4. Accurately weigh 600 mg of 1-nitronaphthalene and 800 mg of TNT with an analytical balance.

[0039]5. Pour the raw materials into a mortar, add distilled water to dissolve and grind. After the medicine is completely mixed and finely ground, put the medicine in a 40-60°C water bath oven, dry it completely, and take out the medicine.

[0040] 6. Pour the dried drug into a 50...

Embodiment 2

[0045] Preparation of 1-nitronaphthalene / picric acid co-crystal

[0046] 1. Accurately weigh 60.00 mg of 1-nitronaphthalene and 80.00 mg of picric acid with an analytical balance.

[0047] 2. Pour the raw materials into a 50ml beaker, and use a 10ml pipette to accurately measure 10ml of dichloromethane and pour it into the beaker.

[0048] 3. Put the magnetic stirring bar into the beaker, turn on the stirring, and put the beaker into a 40°C constant temperature water bath after the drug is completely dissolved. Afterwards, the solvent evaporated slowly, and long needle-shaped single crystals formed after 30 hours.

[0049] 4. Accurately weigh 600 mg of 1-nitronaphthalene and 800 mg of TNT with an analytical balance.

[0050] 5. Pour the raw materials into a mortar, add distilled water to dissolve and grind. After the medicine is completely mixed and finely ground, put the medicine in a 40-60°C water bath oven, dry it completely, and take out the medicine.

[0051] 6. Pour ...

Embodiment 3

[0056] Preparation of 1-nitronaphthalene / MHN co-crystal

[0057] 1. Accurately weigh 400mg of 1-nitronaphthalene and 1000mg of TNT with an analytical balance.

[0058] 2. Pour the raw materials into a mortar, add distilled water to dissolve and grind. After the medicine is completely mixed and finely ground, put the medicine in a 40-60°C water bath oven, dry it completely, and take out the medicine.

[0059] 3. Pour the dried medicine into a 50ml beaker, place it in an oil bath at 105~110°C until it is molten, take it out, place it in dry air to cool naturally, solidify, crush and pass through a 200-mesh sieve. That is, the eutectic powder is obtained.

[0060] 4. Carry out X-ray diffraction analysis of the co-crystal, and the characteristic peaks of the spectrum appear at 8.462°~9.462°, 10.975°~11.975°, 13.797°~14.797°, 21.082°~22.981°, 28.616°~29.616°, 30.534°~ 31.534°, 31.730°~32.731°.

Abstract

The invention discloses an eutectic explosive containing 1-nitronaphthalene, and relates to the eutectic explosive containing the 1-nitronaphthalene and one of trinitrotoluene TNT, picric acid, and mannitol hexanitrate MHN, and a preparation method thereof. Eutectic is formed by the 1-nitronaphthalene with the trinitrotoluene TNT, the picric acid or the mannitol hexanitrate MHN in a mole ratio of 1 : 1; and the three 1-nitronaphthalene eutectics can be prepared by a melting method without organic solvents. The eutectic explosive provided by the invention is greatly improved in thermal stability and sensitivity in addition to inheriting the explosive properties of raw explosives.

Description

technical field [0001] The invention belongs to the technical field of explosive eutectics, in particular to eutectic explosives containing 1-nitronaphthalene and a preparation method thereof. Background technique [0002] Jean-Marie Lehn, the Nobel Prize winner in chemistry in 1987, proposed the concept of supramolecular chemistry "the chemistry of molecular assembly and intermolecular bonds". That is to say, supramolecule is a science that studies molecular aggregates that are complex and ordered and have specific structures and functions formed by the conclusion of intermolecular interactions. Since the supramolecular structure can improve some physical and chemical properties of drugs from the molecular level, such as: solubility, stability and bioavailability, etc., supramolecular chemistry has been more and more applied to the field of drug synthesis in recent years. [0003] Co-crystal belongs to a branch of supramolecular chemistry, which refers to two or more neutr...
