Embodiment 1

[0021] Dissolve 0.213g of s-trinitrobenzene and 0.346g of 1-nitronaphthalene in 50ml of acetonitrile, stir well, and filter to obtain a mixed solution of s-trinitrobenzene and 1-nitronaphthalene. The mixed solution was placed in a constant temperature and humidity chamber, and the temperature was set at 25°C. A few days later, the prismatic light yellow crystals were obtained, filtered by suction, and dried to obtain co-crystals of 3-trinitrobenzene and 1-nitronaphthalene. figure 1 A schematic diagram of the intermolecular forces in the cocrystal of s-trinitrobenzene and 1-nitronaphthalene.

Embodiment 2

[0023] Dissolve 0.426 g of s-trinitrobenzene and 0.173 g of 1-nitronaphthalene in 50 ml of methanol, stir well, and filter to obtain a mixed solution of s-trinitrobenzene and 1-nitronaphthalene. The mixed solution was placed in a constant temperature and humidity chamber, and the temperature was set at 40°C. A few days later, prismatic light yellow crystals were obtained, which were filtered and dried to obtain co-crystals of 3-trinitrobenzene and 1-nitronaphthalene.

Embodiment 3

[0025] Dissolve 0.213g of s-trinitrobenzene and 0.173g of 1-nitronaphthalene in 25ml of ethanol, stir well, and filter to obtain a mixed solution of s-trinitrobenzene and 1-nitronaphthalene. The mixed solution was placed in a constant temperature and humidity chamber, and the temperature was set at 40°C. A few days later, prismatic light yellow crystals were obtained, which were filtered and dried to obtain co-crystals of 3-trinitrobenzene and 1-nitronaphthalene.

Abstract

The invention discloses a eutectic explosive containing trinitrobenzene and 1-nitronaphthalene and a preparing method of the eutectic explosive, and belongs to the technical field of explosive eutectic. The trinitrobenzene and the 1-nitronaphthalene are bonded in a crystal of the same crystal lattice through the intermolecular force by adopting an evaporation solvent method or a suspension method. The thermal stability of the prepared eutectic explosive is greatly improved, the eutectic sensitivity is greatly reduced compared with that of a single-compound explosive, the eutectic melting point is lower than 100 DEG C, and the eutectic explosive can be used as a casting explosive component.

Description

technical field [0001] The invention belongs to the technical field of explosive eutectics, in particular to a eutectic explosive containing s-trinitrobenzene and 1-nitronaphthalene and a preparation method thereof. Background technique [0002] Co-crystal refers to a crystal with specific physical and chemical properties formed by microcosmic combination of two or more neutral molecules in the same lattice through intermolecular forces. As an effective means of modification, eutectic has attracted attention in many fields. Eutectic is a modification at the molecular level, which can be used to change the sensitivity, explosive performance, hygroscopicity, melting point, etc. of explosives, so it has attracted people's attention.
