Abstract

T-jump/FITR spectroscopy was used to study thermal decomposition of energetic material [Co(CHZ)₃] (ClO₄)₂ and [Ni(CHZ)₃](ClO₄)₂ in thin film with rapid heating rate. During the exothermic decomposition process, the major gas products were identified as CO₂, H₂O, HCN, HNCO, and HONO. Time-to-exotherm (t_x) kinetics method derived from the control voltage trace of T-jump/FTIR spectroscopy was introduced to resolve kinetics of the exothermic decomposition reaction of flash pyrolysis of the tide compounds. In the temperature range of 613 ∼653 K under 0.1 MPa Ar atmosphere the Arrhenius activation energy of the exothermic decomposition reaction of [Co(CHZ)₃](ClO₄)₂ was determined to be E _a=39.42 kJ · mol^-1 and lnA=5.93. The Arrhenius activation energy of [Ni(CHZ)₃](ClO₄)₂ was determined to be E_a=60.44 kJ · mol^-1 and lnA=9.40 in the temperature range of 618∼678 K under 0.1 MPa Ar atmosphere.
