Embodiment 1

[0027] In the copper salt complex of p-nitrocalix[8]arene in this embodiment, M is Cu 2+ , a is 8, n is 4, m is 32, j is 16, its general formula is C 56 H 64 N 8 O 40 Cu 4 .

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

[0029] Step 1: Use p-tert-butylcalix[8]arene, nitric acid and glacial acetic acid as raw materials to prepare p-nitrocalix[8]arene and dissolve it 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. is 1: 125, the volume ratio of nitric acid and 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 of the whole process at -2~0°C;

Embodiment 2

[0042]In the metal salt complex of p-nitrocalix[8]arene in this embodiment, M is Cu 2+ , a is 8, n is 3, m is 34, j is 12, the general formula is: C 56 H 58 N 8 O 36 Cu 3 .

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

[0044] In step 2, the Cu(NO 3 ) 2 ·3H 2 03g is dissolved in water to dissolve completely; The copper nitrate solution is added to the N,N-dimethylformamide solution of p-nitrocalixarene, and the molar ratio of p-nitrocalixarene to copper nitrate is 1:3, and in this step Other operations are the same as those in Embodiment 1.

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

Embodiment 3

[0047] In the metal salt complex of p-nitrocalix[8]arene in this embodiment, M is Cu 2+ , a is 8, n is 2, m is 36, j is 8, the general formula is: C 56 H 52 N 8 O 32 Cu 2 .

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

[0049] Weigh out Cu(NO 3 ) 2 ·3H 2 O2g is dissolved in water until completely dissolved; the copper nitrate solution is added to the N,N-dimethylformamide solution of p-nitrocalixarene, so that the molar ratio of p-nitrocalixarene and copper nitrate is 1:2, this step The other operations are the same as in Example 1.

[0050] The other steps were the same as in Example 1, and 4.3 g of the copper salt of p-nitrocalix[8]arene was prepared, and the yield was 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 the kinetic energy and performance of a weapon. Energetic materials are a class of chemical energy materials, which are used in various weapon systems of land, sea and air force, and are the energy for completing launch, propulsion and damage. With the outbreak of modern warfare and the continuous development of modern military science and technology, higher and higher requirements have been placed on energetic materials. However, the energy characteristics and safety performance of energetic materials restrict each other, and the opposites are unified. The catastrophic accidents and the accidental major accidents in the process of ammunition handling, storage, transportation and use ...
