Energetic ion salts of 1-nitramine-2, 4-dimetridazloe and preparation method thereof

Abstract

The invention discloses energetic ion salts of 1-nitramine-2, 4-dimetridazloe and a preparation method thereof, and belongs to the technical field of energetic materials. The synthetic method is as follows: dissolving the 1-nitramine-2, 4-dimetridazloe in deionized water to obtain a pale yellow clear liquid, adding with stirring 0.5 time molar equivalent of potassium carbonate at room temperature for in-situ generation of 1-nitramine-2, 4-dimetridazloe potassium salt, then adding one time molar equivalent of ammonium chloride, hydrazine hydrochloride, guanidine hydrochloride, monoaminoguanidine hydrochloride, diaminoguanidine hydrochloride, triaminoguanidine hydrochloride and 3, 4, 5-triamino-1, 2, 4-triazole hydrochloride, stirring to precipitate a pale yellow solid precipitate, after about 1 hour of reaction, filtering the pale yellow precipitate, further recrystallizing a coarse product by use of an acetone and diethyl ether mixed solvent to obtain a pure product. The synthetic method of the invention is simple, mild in condition and high in yield, and is environmental friendly due to using of the deionized water as a solvent. The density of involved seven salts is 1.70-1.93g cm<-3>, the detonation velocity calculated by EXPLO software is between 8370 and 9209 m s<-1>, the detonation pressure is between 29.3 and 40.5 GPa, the actually measured impact sensitivity is 4-40J, the detonation performance is excellent, and the energetic ion salts are potential energetic materials.

Description

technical field

[0001] The invention relates to 1-nitroamine-2,4-dinitroimidazole energetic ion salts and a preparation method thereof, belonging to the technical field of energetic materials. Background technique

[0002] With the development of military science and society, designing and synthesizing new high-energy and low-sensitivity energetic materials to meet the high comprehensive performance requirements of modern weapons and equipment is of great significance to national defense construction and national economy. In the past ten years, energetic ionic compounds have become the focus of new high-energy-density energetic materials because of their advantages such as lower vapor pressure, higher density, enthalpy of formation, and stability, and the performance can be optimized through the modification and combination of anions and cations. hotspot.

[0003] At present, the research on N-anion-based energetic ion salts based on heterocyclic compounds with high nitroge...
