Pyrazolotriazine high-nitrogen energetic molecules and synthesis method thereof

Abstract

The application discloses a kind of pyrazolotriazine high-nitrogen energetic molecules and synthesis method thereof, with 3,4-dicyano-5-amino pyrazole, 3-amino-4-cyanopyrazole as raw material, first utilize sodium nitrite and concentrated hydrochloric acid and its reaction synthesis diazonium salt intermediate, then diazonium salt intermediate is closed loop reaction to obtain closed loop product, closed loop product is reacted in sodium azide to obtain 3-nitro-8-cyano-7-(1H-tetrazol-5-yl) pyrazole [5,1-c] [1,2,4] triazine-4-amino, 3-nitro-7,8-di(1H-tetrazol-5-yl) pyrazole [5,1-c] [1,2,4] triazine-4-amino, 3-nitro-8-(1H-tetrazol-5-yl) pyrazole [5,1-c] [1,2,4] triazine-4-amine, 3-nitro-8-(1H-tetrazol-5-yl) pyrazole [5,1-c] [1,2,4] triazine-4-amine is reacted in ammonia water to obtain 3-nitro-8-(1H-tetrazol-5-yl) pyrazole [5,1-c] [1,2,4] triazine-4-amine ammonium salt;Closed loop product is nitrated in concentrated nitric acid, concentrated sulfuric acid to obtain 3,8-dinitro-5-pyrazole [5,1-c] [1,2,4] triazine-4-amine;The application obtains five kinds of energetic materials, can be used as potential substitute of RDX and TATB explosive.
