Nonisothermal decomposition kinetics, specific heat capacity, and adiabatic time-to-explosion of Zn(NH3)2(FOX-7)2

摘要: A new energetic zinc-FOX-7 complex, Zn(NH3)2(FOX-7)2 (FOX-7 = 1,1-diamino-2,2-dinitroethylene), was first synthesized. Thermal decomposition behavior and nonisothermal kinetics of were studied with DSC TG/DTG methods. The kinetic equation obtained is $$ \frac{{{\text{d}}\alpha }}{{{\text{d}}T}} = \frac{{10^{13.99} }}{\beta }4(1 - \alpha )[ \ln (1 )]^{{{3 \mathord{\left/ {\vphantom {3 4}} \right. \kern-0pt} 4}}} \exp ( 1.448 \times 10^{5} /RT) $$ . self-accelerating temperature (T SADT) critical thermal explosion b) are 183.2 195.8 °C, respectively. specific-heat capacity determined a micro-DSC method, the molar-heat 454.6 J mol−1 K−1 at 298.15 K. Adiabatic time-to-explosion also estimated to be about 20 s. stability good higher than that analogous Cu(NH3)2(FOX-7)2.
