摘要: A novel energetic material, 1-amino-1-(2,4-dinitrophenylhydrazinyl)-2,2-dinitroethylene (APHDNE), was synthesized by the reaction of 1,1-diamino-2,2-dinitroethylene (FOX-7) and 2,4-dinitrophenylhydrazine in N-methyl pyrrolidone (NMP) at 110 . The theoretical investigation on APHDNE curried out B3LYP/6-311+ method. IR frequencies analysis NMR chemical shifts were performed compared with experimental results. thermal behavior studied DSC TG/DTG methods, can be divided into two crystal phase transition processes three exothermic decomposition processes. enthalpy, apparent activation energy pre-exponential factor first obtained as -525.3 kJ , 276.85 respectively. critical temperature explosion is 237.7 specific heat capacity determined micro-DSC method calculation method, molar 363.67 J 298.15 K. adiabatic time-to-explosion also calculated to a certain value between 253.2-309.4 s. has higher stability than FOX-7.
