Problems solved by technology

However, the current energetic ion salts generally have the characteristics of low oxygen balance, and the nitrogen-rich heterocyclic compounds with negative oxygen balance are mainly used as the anions of the energetic ion salts, which leads to the low oxygen balance of the obtained energetic ion salts. Earth, the energy is also lower

Abstract

The invention discloses an N-nitrotrinitroethyl carbamate energetic ionic salt and a preparation method and application thereof. The method includes: dissolving N-nitrotrinitroethyl carbamate into an organic solvent to react with alkaline carbonates, bicarbonates or aminoazole compounds at the room temperature to obtain the N-nitrotrinitroethyl carbamate energetic ionic salt. The N-nitrotrinitroethyl carbamate energetic ionic salt is an energetic compound, high in oxygen balance and detonation velocity and expected to be applied to gunpowder, explosives and solid propellants.

Description

Technical field [0001] The invention relates to an N-nitrotrinitroethyl carbamate energetic ion salt, a preparation method and an application, and belongs to the technical field of energetic materials. Background technique [0002] Modern warfare requires weapons and equipment to achieve long-range strikes and high-efficiency damage. Both propellants and explosives are required for high-energy. This requires energetic materials as energy carriers to achieve high-energy first. Energetic ionic salts have the characteristics of low vapor pressure and low sensitivity, and are currently one of the hot spots in the development of high-energy compounds. Oxygen balance is an important parameter of energetic compounds. Improving oxygen balance when the oxygen balance is less than or equal to zero can effectively increase the energy level of energetic compounds. However, the current energetic ionic salts generally have the characteristics of low oxygen balance, and mainly use nitrogen-ric...
