Embodiment 1

[0021] The example MOF[CuBTA 2 ] (Hgua) 2 2H 2 Preparation of O:

[0022] Disperse 1,1'-bis(1-H-tetrazole)amine (16.92g, 0.11mol) in deionized water (500mL) at room temperature, and add potassium hydroxide (12.06g, 0.22mol) to form a pH value of 10.2 transparent solution; after heating up to 70°C, add guanidine hydrochloride (26.52g, 0.28mol) and copper chloride dihydrate (9.38g, 0.055mol) to the above solution, then cool down naturally to precipitate a black precipitate; then use the precipitate The energetic MOF [CuBTA 2 ] (Hgua) 2 2H 2 O (20.8 g), 72.0% yield.

Embodiment 2

[0024] The difference between this example and Example 1 is that the pH value is 9.0, and the product yield is 50.8%.

Embodiment 3

[0026] The difference between this example and Example 1 is that the reaction is carried out after the temperature is raised to 90° C., and the yield of the obtained product is 65%.

Abstract

The invention discloses an MOF [CuBTA2] (Hgua) 2 * xH2O compound and a preparation method of the MOF [CuBTA2] (Hgua) 2 * xH2O compound. The disclosed [CuBTA2] (Hgua) 2 * xH2O compound is prepared by carrying out a coordination reaction on 1, 1 '-bis (1-H-tetrazole) amine, guanidine hydrochloride, a water-soluble copper salt and water under the condition of 70 DEG C to 90 DEG C. The invention further discloses a preparation method of the [CuBTA2] (Hgua) 2 * xH2O compound. The compound has an obvious adjusting effect on the combustion performance of a modified double-base propellant, the combustion rate of the propellant under low pressure can be remarkably increased, the combustion rate pressure index of the propellant under 3-10 MPa is reduced, and the compound is a green combustion catalyst.

Description

technical field [0001] The present invention relates to an energetic MOF based on 1,1'-bis(1-H-tetrazole)amine [CuBTA 2 ] (Hgua) 2 2H 2 O, this compound can be used as a green combustion catalyst for modified double-base propellants. [0002] technical background [0003] The combustion performance of solid propellant determines its energy release characteristics, which is closely related to the tactical performance of the weapon system. Combustion catalyst is an indispensable functional component in the solid propellant formula. Since the discovery of the speed-up effect of lead-containing compounds on double-base gunpowder in 1948, researchers began to study the influence of lead-containing compounds on the combustion performance of propellants and found that The addition of lead-containing compounds can significantly increase the burning rate of double-base propellants at low pressure, resulting in the so-called "overspeed combustion phenomenon", and within a certain pr...
