Embodiment 1

[0023] Add 2.06g (10.0mmol) of 5,5'-bitetrazol-1,1'-dihydroxy dihydrate into a 100mL beaker, then add 50mL of deionized water, and use a magnetic stirrer at a speed of 250 rpm Stir for 5 minutes, then sonicate for 5 minutes. 1.87g (10mmol) of copper nitrate was added to a 50mL beaker, followed by 20mL of deionized water, stirred with a magnetic stirrer at a speed of 250 rpm for 5 minutes, and then ultrasonicated for 5 minutes. The above two solutions were simultaneously poured into a microwave reaction tube and placed in a microwave reactor. The microwave reactor was turned on, and the temperature was raised to 80° C. within two minutes and held for 15 minutes. After the reaction, the microwave reaction tube was taken out, and the solution in the reaction tube was quickly poured into a three-necked flask preheated to 80°C, stirred at a speed of 200 rpm with a magnetic stirrer, and dropped to 50°C / hour. 15°C. After filtering, the filter cake was washed 3 times with deionized...

Embodiment 2

[0025] Add 3.09 g (15.0 mmol) of 5,5'-bitetrazol-1,1'-dihydroxy dihydrate into a 100 mL beaker, then add 60 mL of deionized water, and use a magnetic stirrer at a speed of 250 rpm Stir for 5 minutes. 1.87g (10mmol) of copper nitrate was added to a 50mL beaker, followed by 20mL of deionized water, and the magnetic stirrer was stirred at a speed of 250 rpm for 5 minutes. Mix the above two solutions into the same beaker and sonicate for 5 minutes. The above mixed solution was poured into a microwave reaction tube and placed in a microwave reactor. The microwave reactor was turned on, and the temperature was raised to 90° C. within two minutes and held for 15 minutes. After the reaction, the microwave reaction tube was taken out, and the solution in the reaction tube was quickly poured into a three-necked flask preheated to 90°C, stirred at a speed of 200 rpm with a magnetic stirrer, and dropped to 100°C / hour. 5°C. After filtering, the filter cake was washed 3 times with deion...

Embodiment 3

[0027] Add 2.06g (10mmol) of 5,5'-bitetrazol-1,1'-dihydroxy dihydrate into a 100mL beaker, then add 50mL of deionized water, and stir with a magnetic stirrer at a speed of 250 rpm 5 minutes, followed by 5 minutes of sonication. 3.0 g (16 mmol) of copper nitrate was added to a 50 mL beaker, followed by 25 mL of deionized water, stirred with a magnetic stirrer at a speed of 250 rpm for 5 minutes, and then ultrasonicated for 5 minutes. The above two solutions were simultaneously poured into a microwave reaction tube and placed in a microwave reactor. The microwave reactor was turned on, and the temperature was raised to 80° C. within two minutes and held for 15 minutes. After the reaction, the microwave reaction tube was taken out and placed in a cold water bath to drop to 5° C. at a rate of 200° C. / hour. After filtering, the filter cake was washed 3 times with deionized water at 5°C. After natural drying, 4.31 g of light green copper-BTO energetic metal coordination polymer w...

Abstract

The invention relates to a copper-BTO energetic metal coordination polymer and a rapid preparation method thereof, belonging to synthesis of a metal coordination polymer in the field of energetic materials. The method comprises the following steps: separately dissolving a 5,5'-bistetrazole-1,1'-dioxy ligand compound and an inorganic copper salt in a same solvent, and separately carrying out ultrasonic treatment; mixing the two above-mentioned solutions in a microwave reaction tube, and placing the microwave reaction tube into a microwave reactor; starting the microwave reactor, carrying out rapid heating to a certain temperature, and subjecting the two solutions to a complete reaction in a short period of time; and after the reaction is completed, carrying out cooling, filtering and natural air-drying so as to obtain the copper-BTO energetic metal coordination polymer. The preparation method provided by the invention has the advantages of simple steps, mild reaction conditions, reliable product quality and extremely rapid reaction speed, and greatly reduces the time of coordination compound preparation. The copper-BTO energetic metal coordination polymer prepared by using the preparation method provided by the invention has the advantages of good thermal stability, low mechanical sensitivity and high application values.

Description

technical field [0001] The invention relates to a copper-BTO energetic metal coordination polymer and a rapid preparation method thereof, belonging to the synthesis of metal coordination polymers in the field of energetic materials. Background technique [0002] The energetic metal coordination polymer refers to the energetic coordination polymer with metal ions as the skeleton, and the metal ion, nitrogen-rich structure and ordered structure contained in the structure enable the energetic metal coordination polymer to obtain higher density and release greater energy. In addition, through the control of its chemical structure, the energetic metal coordination polymer can obtain lower mechanical sensitivity and thermal sensitivity, so that the energetic metal coordination polymer has more application value. [0003] As a typical representative of nitrogen-rich compounds, bitetrazole has always been the focus of research by scientists at home and abroad. Among them, 5,5'-bit...
