Abstract

A novel high energetic material, 1-amino-1-methylamino-2,2-dinitroethylene (AMFOX-7), was synthesized through 1,1-diamino-2,2-dinitroethylene (FOX-7) reacting with methylamine in N-methyl pyrrolidone (NMP) at 80.0 °C, and its structure was determined by single crystal X-ray diffraction. The crystal is monoclinic, space group P2₁/m with crystal parameters of a=6.361(3) Å, b=7.462(4) Å, c=6.788(3) Å, β=107.367(9)^o, V=307.5(3) Å³, Z=2, μ=0.160 mm^-1, F(000)=168, D_c=1.751 g•cm^-3, R¹=0.0463 and wR²=0.1102. Thermal decomposition of AMFOX-7 was studied, and the enthalpy, apparent activation energy and pre-exponential constant of the exothermic decomposition reaction are 303.0 kJ•mol^-1, 230.7 kJ•mol^-1 and 10^21.03 s^-1, respectively. The critical temperature of thermal explosion is 245.3 °C. AMFOX-7 has higher thermal stability than FOX-7.
