Abstract

A superior oxidizer, a derivative of trinitropyrazole, 3,4,5-trinitro-1-(nitromethyl)-1H-pyrazole (TNNMP), was obtained in good yield by the reaction of ammonium 4-amino-3,5-dinitropyrazolate with bromonitromethane followed by oxidation with a mixture of H2O2/H2SO4. Characterization of TNNMP shows that in addition to having good oxygen balance (+18.3%) and detonation performance (Dv = 8858 m s−1; P = 35.1 GPa), it concomitantly has high thermal stability (Td = 202 °C) and acceptable sensitivities (IS = 14 J; FS = 120 N). These attractive properties suggest TNNMP as a promising perchlorate free high energy density oxidizer and a potential replacement for ammonium perchlorate.
