High-energy density material and synthesis method thereof

Abstract

The invention discloses a synthesis method of a high-energy density material, which comprises the following steps: a) preparing [2,2'-di(1,3,4-oxadiazole)]-5,5'-diamine: adding oxalyl dihydrazide and potassium bicarbonate to a solvent, performing stirring, adding cyanogen bromide in batches, performing keeping for 10h-2d, adding water in a reaction, and performing stirring, filtering, water washing and drying; b) preparing [2,2'-di(1,3,4-oxadiazole)]-5,5'-dinitramide: allowing [2,2'-di(1,3,4-oxadiazole)]-5,5'-diamine to generate a nitration reaction in a nitration system to obtain [2,2'-di(1,3,4-oxadiazole)]-5,5'-dinitramide. The invention further provides the high-energy density material. The synthesis method of the high-energy density material is developed by taking oxalyl dihydrazide as a raw material, and is low in cost, mild in reaction and simple to operate.

Description

technical field

[0001] The invention belongs to the field of energetic material synthesis, and in particular relates to a novel high-energy-density material and a synthesis method thereof. Background technique

[0002] Modern weapons require energetic materials to have as high energy as possible, and the synthesis of high energy density has become an important content in the field of energetic materials in recent decades. In fact, density is one of the most important properties of high-energy-density materials. The density directly affects the energy level of energetic materials, because the detonation velocity of energetic materials increases with the increase of density, and the detonation pressure is even related to the square of density. Proportional. However, the current development density reaches 2.0g / cm 3 Explosives are a great challenge, and so far only a few cases have been reported with densities exceeding 2.0g / cm 3 of dynamite. However, considering comprehens...
