Abstract

The invention relates to diazo(N-dinitryl ethyl) furazan energy-containing ionic salts and a preparation method thereof, and belongs to the technical field of energy-containing materials. The synthetic method comprises the following steps of: performing acid-base neutralization reaction of diazo(N-dinitryl ethyl) furazan and 2 times of organic base in mole to obtain corresponding energy-containing ionic salts or performing reaction of diazo(N-dinitryl ethyl) furazan sylvite with 2 times of hydrochloride in mole of corresponding cations; and filtering the precipitate to obtain the target product. The synthetic method provided by the invention is simple and easy to industrialize. 6 energy-containing ionic salts are better in thermal stability, the calculated detonation performance of the energy-containing ionic salts is far superior to that of TNT (Trinitrotoluene), and the detonation performance of part of compounds is approximate to that of RDX (Cyclotrimethylene Trinitramine). The diazo(N-dinitryl ethyl) furazan energy-containing ionic salts can be used as substituents of a nitroform explosive and a furazan explosive for improving oxygen balance in a mixed explosive and used as an oxygen supply component in a propellant.

Description

technical field

[0001] The invention relates to a heavy (N-dinitroethyl) furoxan energetic ion salt and a preparation method thereof, belonging to the technical field of energetic materials. Background technique

[0002] Energetic materials as weapon energy carriers must meet the requirements of high energy density, low vulnerability and environmental adaptability (Journal of Explosives and Explosives, 2005, 28(4): 9-13). However, these properties are always contradictory to some extent: materials with good stability and low sensitivity usually have low energy, and when the energy is high, the chemical and physical stability will deteriorate. At present, the development of energetic materials has changed from purely pursuing high-energy materials to a new stage of searching for new types of high-energy and low-sensitivity explosives. There is an urgent need for energetic materials with excellent comprehensive properties such as high energy, insensitivity, stability, and non-...
