Abstract

Abstract: Several new energetic low‐melting monosubstituted polynitroalkoxy‐1, 2, 4, 5‐tetrazines have been synthesized. Their thermal stability has been investigated by the methods of isothermal and non‐isothermal kinetics. These molecules display good thermal stability: trinitroethoxytetrazine can be safely kept in the molten state for about a week, dinitro‐fluoroethoxy derivative is significantly more stable. The volatility of the studied compounds increases in the series of substituents as (NO2 )3 CCH2 O2 )2 CCH2 O3 (NO2 )2 CCH2 O. The vapor pressure over the liquid fluorine derivative turned out to be 2 times less than the vapor pressure over the liquid trinitroazetidine (TNAZ). The combustion rates of synthesized low‐melting explosives of the tetrazine series, as well as other volatiles like TNT, are controlled by reactions in the flame (gas‐phase combustion mechanism). It was shown that trinitro and fluorodinitro derivatives most fully meet the requirements for the melt‐castable explosives. Abstract :
