【摘要】The thermal behavior and non-isothermal kinetics of the exothermic decomposition reaction of 1-amino-1-hydrazino-2,2-dinitroethylene (AHDNE) were studied with DSC and TG/DTG methods.The kinetic equation obtained is dα/dT=1019.29(1-α)exp(-1.88×104/T)/β.The critical temperature of thermal explosion is 98.16 ℃.The specific heat capacity of AHDNE was determined,and the standard molar specific heat capacity is 211.86 J·mol-1·K-1 at 298.15 K.The adiabatic time-to-explosion of AHDNE was also calculated to be 59.21 s.AHDNE is unstable and has much lower thermostability than 1,1-diamino-2,2-dinitroethylene (FOX-7). 【总页数】7页(665-671) 【关键词】 【
