1-偕二硝基-3-硝基-5-叠氮吡唑钾盐的合成、结构与性能
Synthesis,Structure,and Performance of Potassium 1-(Dinitromethyl)-3-nitro-5-azidopyrazole
摘要
Abstract
1-(Trinitromethyl)-3-nitro-5-azidopyrazole(compound 1)was synthesized from 1-acetonyl-3,5-dinitropyrazole via ni-tration.The 1-(dinitromethyl)-3-nitro-5-azidopyrazole potassium salt(compound 2)was further prepared through a salification reaction with KI.The structures of both two compounds were characterized by Fourier-transform infrared spectroscopy(FT-IR),nuclear magnetic resonance(NMR),and single crystal X-ray diffraction.The results show that compound 2 contains both azido and dinitromethylene groups,exhibiting superior overall properties of high decomposition temperature(151.41℃)and detona-tion velocity(8369 m•s-1).The relatively high sensitivity towards external mechanical stimuli make it suitable to be a primary ex-plosive.The detonation performance of compound 2 was further analyzed using Gaussian and Explo5 software.This research pro-vides valuable insights for the design of novel green explosives.关键词
