The thermal behavior of 4,6-bis-(5-amino-3-nitro-1,2,4-triazol-1-y1)-5-nitropyrimidine (BANTNP) was studied under a non-isothermal condition by DSC, PDSC and TG/DTG methods. The kinetic parameters (Ea and A) of the exothermic decomposition reaction are 304.52 kJ center dot mol(-1) and 10(24.47) s(-1) 0.1 MPa, 272.52 kJ center dot mol(-1) and 10(21.76) s(-1) at 5.0 MPa, respectively. The kinetic equation at 0.1 MPa can be expressed as:
d alpha/dT = 10(25.3)/beta(1-alpha)3/4exp(-3.8044x10(4)/T)
The critical temperature of thermal explosion is 588.28 K. The specific heat capacity of BANTNP was determined with a Micro-DSC method, and the standard molar specific heat capacity is 397.54 J center dot mol(-1)center dot K(-1) at 298.15 K. The adiabatic time-to-explosion of BANTNP was calculated to be 11.75 s.
