Embodiment 1

[0023] First weigh 0.30g of C60, add 200mL of ethylenediamine into a 250mL three-neck round bottom flask, and under nitrogen protection, react at 80°C for 4 days until the color of the solution turns yellowish brown, then stop the reaction. Excess ethylenediamine solution was removed by rotary evaporation at 55° C. to obtain a large amount of tan viscous material. Dissolve the viscous matter with 8ml of distilled water, and then add 100 mL of acetone, a large number of brown flocculent precipitates precipitate out, filter under reduced pressure, collect the precipitate, and vacuum-dry at 45°C to obtain brown fullerene ethylenediamine. The reaction equation is shown in Formula (2). Then weigh 1.00 g of fullerene ethylenediamine and 16 ml of nitric acid with a concentration of 1 mol / L, control the temperature to 40° C., and stir for 0.5 h. The reaction liquid was evaporated under reduced pressure to remove water and nitric acid to obtain a brown solid, which was dried under vac...

Abstract

The invention discloses a fullerene ethylenediamine nitrate as well as a preparation method and an application thereof. Firstly, fullerene C60 and ethylenediamine are taken as raw materials, fullerene ethylenediamine is prepared by the aid of a nucleophilic addition principle, and the fullerene ethylenediamine reacts with nitric acid so that the fullerene ethylenediamine nitrate is obtained. The fullerene ethylenediamine nitrate has the advantages of oxidant ammonium nitrate (AN), can avoid disadvantages of hygroscopicity, and crystal transformation of AN, and can be used as an oxidant to be applied in a novel solid rocket propellant or explosive.

Description

technical field [0001] The invention belongs to the technical field of compound synthesis, and in particular relates to fullerene ethylenediamine nitrate and its preparation technology. The fullerene ethylenediamine nitrate can be used as an oxidant for solid rocket propellants and explosives. Background technique [0002] Solid propellant is a kind of energetic composite material with specific properties, which is the power source of various solid motors of missiles and space vehicles. Solid propellant technology is a common technology, supporting technology, and restrictive technology for weapons and equipment. Its performance directly affects the survivability and combat effectiveness of strategic and tactical missiles. [0003] Future tactical missiles not only require solid propellants to have high energy, that is, high specific impulse and high density, but also require solid propellants to have low signature, insensitivity (low vulnerability) and Features such as l...
