Embodiment 1

[0022] Lead content is the preparation method of 57.52% fullerene amine lead salt:

[0023] First weigh 0.05g C 60 , add 25mL of ethylenediamine into a 100mL three-necked round bottom flask, under the protection of nitrogen, react at 80°C for 4d 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. The viscous obtained was dissolved in 2ml of distilled water, and then 25mL of acetone was added, a large amount of tan flocculent precipitates were precipitated, filtered, collected, and vacuum-dried at 45°C to obtain tan fullerene amine. Weigh 0.1g of fullerene amine and dissolve in 10ml of distilled water; weigh 0.291g of lead nitrate and dissolve in 10mL of distilled water, add dropwise to the fullerene amine solution while stirring, and react at 35°C for 2h. The reaction solution was centrifuged, the supernatant was discarded, ...

[0026] Lead content is the preparation method of 42.3% fullerene amine lead salt:

[0027] First weigh 0.05g C 60 , add 25mL of ethylenediamine into a 100mL three-necked round bottom flask, under the protection of nitrogen, react at 80°C for 4d until the color of the solution turns yellowish brown, then stop the reaction. Excess ethylenediamine solution was spun off at 55°C to yield a large tan goo. The viscous obtained was dissolved in 2ml of distilled water, and then 25mL of acetone was added, a large amount of tan flocculent precipitates were precipitated, filtered, collected, and vacuum-dried at 45°C to obtain tan fullerene amine. Weigh 0.1g of fullerene amine and dissolve in 10ml of distilled water; weigh 0.2328g of lead nitrate and dissolve in 10mL of distilled water, add dropwise to the fullerene amine solution while stirring, and react at 35°C for 2h. The reaction solution was centrifuged, the supernatant was discarded, and washed repeatedly with distilled water for ...

Abstract

The invention discloses a fullerene amine-lead salt derivative, its preparation method and application. The preparation method comprises: first taking fullerene C60 and amine as raw materials, which then undergo a nucleophilic addition reaction to synthesize a fullerene amine derivative, and reacting the fullerene amine derivative with lead nitrate to prepare the fullerene amine-lead salt derivative, which can be applied as a combustion catalyst in novel solid rocket propellants.

Description

technical field [0001] The invention belongs to the technical field of compound synthesis, and in particular relates to fullerene amine lead salt and its preparation method and application. The fullerene amine lead salt can be used as a combustion catalyst in solid rocket propellants. Background technique [0002] In the 21st century, the main goal of solid propellants for rocket engines is to develop high-energy, high-burning-rate, high-strength, low-sensitivity, recyclable propellants. In high-tech wars, the vulnerability of weapons puts forward new requirements for rocket engines. Therefore, insensitive propellants, a new concept, have become a hot research topic at home and abroad. [0003] In modern rocket and missile engine systems, there are two types of propellants commonly used: solid propellants and liquid propellants. The former is the dominant energy source in engines and is the most commonly used due to its ease of use, high performance and affordability. At ...
