Problems solved by technology

[0003] 2,4,6-Trinitrotoluene (TNT) is widely used as a melting and casting agent in the formulation of melting and casting explosives. It has the characteristics of low melting point, good safety, wide source of raw materials, and low price. Large and other disadvantages seriously restrict its further development
At present, there is no public literature report about the preparation of TNT / TNCB eutectic explosive

Embodiment 1

[0031] At room temperature, 30ml of acetone was added into the three-necked flask, and then a sufficient amount of TNT was added under stirring, dissolved and filtered to obtain a saturated solution of TNT. Then add a sufficient amount of TNCB, stir, dissolve, and filter, and the obtained filtrate is a saturated solution of TNT-TNCB co-crystallization. Put the filtrate in a petri dish, then put it still in a thermostat at 30°C, let the solvent evaporate, precipitate crystals, and dry to obtain TNT / TNCB eutectic explosive.

Embodiment 2

[0033] At room temperature, 50ml of ethanol was added into the three-necked flask, and then a sufficient amount of TNT was added under stirring, dissolved and filtered to obtain a saturated solution of TNT. Then add a sufficient amount of TNCB, stir, dissolve, and filter, and the obtained filtrate is a saturated solution of TNT-TNCB co-crystallization. Put the filtrate in a beaker, then place it still in a thermostat at 35°C, let the solvent evaporate, precipitate crystals, and dry to obtain TNT / TNCB eutectic explosive.

Embodiment 3

[0035] At room temperature, 60ml of absolute ethanol was added into a three-necked flask, and then a sufficient amount of TNT was added under stirring, dissolved and filtered to obtain a saturated solution of TNT. Then add a sufficient amount of TNCB, stir, dissolve, and filter, and the obtained filtrate is a saturated solution of TNT-TNCB co-crystallization. Put the filtrate in a beaker, then place it still in a thermostat at 35°C, let the solvent evaporate, precipitate crystals, and dry to obtain TNT / TNCB eutectic explosive.

Abstract

The invention discloses a TNT (Trinitrotoluene) / TNCB (Trinitro-Chlorobenzene) co-crystalized explosive and a preparation method thereof. The preparation method comprises the following steps: I, preparing a TNT-TNCB saturated solution, adding TNT into a crystallization solvent at the temperature of 20 to 50 DEG C, dissolving and filtering to obtain a TNT saturated solution, adding TNCB into the TNT saturated solution for dissolving, and filtering to obtain a TNT-TNCB mixed saturated solution; II, preparing the TNT / TNCB co-crystalized explosive: placing the TNT-TNCB mixed saturated solution into a culture dish, standing in a constant-temperature incubator, evaporating the solvent, sequentially performing crystal nucleus forming, crystalline grain growing, a crystal forming, filtering and drying to obtain the TNT-TNCB co-crystalized explosive. The prepared TNT / TNCB co-crystalized explosive provided by the invention has a low melting point, superior security and excellent detonation performance, can be taken as a novel melting and casting solvent, and has a good application prospect in a high-energy insensitive melting and casting explosive formula. The preparation method has the advantages of simple process, convenience in operation, high security and high product quality.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to a preparation method of 2,4,6-trinitrotoluene (TNT) and 2,4,6-trinitrochlorobenzene (TNCB) (TNT / TNCB) eutectic explosive , the present invention has good application prospect in insensitive cast explosives. Background technique [0002] There is an inherent contradiction between the energy and safety of existing energetic materials, that is, the higher the energy of explosives, the higher the sensitivity, and the lower the sensitivity, the lower the energy. Therefore, this contradiction seriously restricts the research, development and application of energetic materials. At present, as a new modification method of energetic materials, eutectic explosives have gradually become a new strategy for constructing new energetic materials and regulating their properties, and have become a research hotspot in the field of energetic materials at home and abroad. Through the fo...
