Embodiment 1

[0023] Pb(BTO)(H 2 O) the preparation method of coordination compound:

[0024] First weigh 20.6mg 1,1’-dihydroxy-5,5’-bistetrazole (BTO), 33.1mgPb(NO 3 ) 2 Add it to a 10mL polytetrafluoroethylene reactor, then add 3mL of water, immediately a large amount of white precipitate is formed, seal the reactor and heat it to 130°C for 3 days, then stop heating. Naturally cool at room temperature and stand for 3d to obtain a transparent solution with crystals at the bottom of the reactor. The reaction solution is filtered and separated to obtain white crystals. The crystals are vacuum-dried to obtain 23mg of Pb(BTO)(H 2 O) coordination compounds.

[0025] The lead content in the product measured by atomic absorption is 52.70%, and the infrared spectrum of the Pb(BTO)(H2O) coordination compound is shown in figure 1 , it can be seen from the infrared data that the O-H stretching vibration of the complex is located at 3434cm -1 , C=N stretching vibration peaks, N=N stretching vibra...

Abstract

The invention discloses a lead coordination compound Pb(BTO)(H2O) as well as a preparation method and an application thereof. 1,1-dyhydroxy-5,5'-bistetrazole(BTO) and lead nitrate are taken as raw materials, the coordination compound is synthesized with a hydrothermal method, and the lead coordination compound can be taken as a combustion catalyst to be applied to a novel solid rocket propellant.

Description

technical field [0001] The invention belongs to the technical field of artificial synthesis of compounds, in particular to Pb(BTO)(H 2 O) coordination compound 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. Under the current high-tech warfare conditions, all kinds of rockets and missile weapons have put forward higher requirements for flight speed, so the role of solid propellant combustion rate adjustment technology as a power source is becoming more and more prominent. At present, the use of burning rate catalysts to adjust the combustion performance of propellants has been extensively studied. As the power source of rocket and missile engines, the performance of solid propel...
