Embodiment 1

[0027] The copper salt complex of p-nitrocalix [8] arene of the present embodiment, M is Cu 2+ , a is 8, n is 4, m is 32, j is 16, and its general formula is C 56 h 64 N 8 o 40 Cu 4 .

[0028] The preparation method of the copper salt complex of above-mentioned p-nitrocalix [8] arene can be as follows:

[0029] Step 1: Prepare p-nitrocalix[8]arene from p-tert-butylcalix[8]arene, nitric acid and glacial acetic acid and dissolve in N,N-dimethylformamide

[0030] Step 1.1: Preparation of p-nitrocalix[8]arene

[0031] Step 1.1.1: Weigh 12g of p-tert-butylcalix[8]arene and slowly add it into a mixed solution containing 50mL of nitric acid and 115mL of glacial acetic acid. The molar ratio of p-tert-butylcalix[8]arene to nitric acid 1:125, the volume ratio of nitric acid to glacial acetic acid is 1:2.3, add dropwise while stirring, continue to stir for 5 hours after the dropwise addition, and keep the temperature in the whole process at -2~0°C;

[0032] Step 1.1.2: After stir...

Embodiment 2

[0042]The metal salt complex of p-nitrocalix [8] arene of the present embodiment, M is Cu 2+ , a is 8, n is 3, m is 34, j is 12, and its general formula is: C 56 h 58 N 8 o 36 Cu 3 .

[0043] The preparation method of the metal salt complex of above-mentioned p-nitrocalix [8] arene is as follows:

[0044] In step 2, weigh Cu(NO 3 ) 2 ·3H 2 O 3g is dissolved in water to dissolve completely; Copper nitrate solution is added to the N of p-nitrocalixarene, in the N-dimethylformamide solution, the mol ratio of p-nitrocalixarene and copper nitrate is 1: 3, this step Other operations are the same as in Example 1.

[0045] The other steps were the same as in Example 1 to prepare 4.6 g of copper salt of p-nitrocalix[8]arene, with a yield of 80.1%.

Embodiment 3

[0047] The metal salt complex of p-nitrocalix [8] arene of the present embodiment, M is Cu 2+ , a is 8, n is 2, m is 36, j is 8, and its general formula is: C 56 h 52 N 8 o 32 Cu 2 .

[0048] C above 56 h 52 N 8 o 32 Cu 2 The preparation method is as follows:

[0049] Weigh Cu(NO 3 ) 2 ·3H 2 O 2g is dissolved in water until fully dissolved; the copper nitrate solution is added to the N, N-dimethylformamide solution of p-nitrocalixarene, so that the mol ratio of p-nitrocalixarene and copper nitrate is 1: 2, this Other operations in the steps are the same as those in Example 1.

[0050] The other steps were the same as in Example 1 to prepare 4.3 g of copper salt of p-nitrocalix[8]arene, with a yield of 77.6%.

Abstract

The invention belongs to the technical field of energetic materials and relates to a metal salt complex of p-nitrocalixarene and a preparation method thereof. The general formula of the metal salt complex of the p-nitrocalixarene is MnC7aHm plus 2jNaO3a plus j. The metal salt complex of p-nitrocalixarene and the preparation method thereof have the beneficial effects that an energetic compound of an energetic group, i.e. the p-nitrocellulose [4, 6, 8] energetic metal salt complex is obtained through reacting the p-nitrocalixarene and soluble transition metal salt; the characteristics of easiness in synthesis, high melting point, good heat stability and good chemical stability of calixarene are fully utilized; as the metal salt complex is taken as a combustion catalyst of a energetic material under a high-energy high pressure, the sensitivity value of the energetic material is reduced to a certain degree; and moreover, the metal salt complex has the synergetic effect, so that the energy content of the energetic material is increased. The preparation method has the advantages of fewer steps, simplicity and fewer byproducts and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, in particular to an insensitive energetic fuel catalyst p-nitrocalix[4,6,8]arene metal salt complex and a preparation method thereof. Background technique [0002] Energy is a key factor in determining a weapon's kinetic energy and ability to do work. Energetic material is a kind of chemical energy material, which is used in various weapon systems of land, sea and air force, and is the energy to complete launch, propulsion and damage. With the outbreak of modern warfare and the continuous development of modern military science and technology, higher and higher requirements are put forward for energetic materials. However, the energy characteristics and safety performance of energetic materials are mutually restricted, and the opposites are unified. The catastrophic accidents that occurred in the past few years and the unexpected major accidents in the process of ammunition handling,...
