Flash pyrolysis of MnTC([Mn2(TNR)2(CHZ)2(H2O)4]·2H2O) and NiCT([Ni(CHZ)3](TNR)·5H2O) is conducted by using T-jump/FTIR spectroscopy under 0.1 MPa Ar atmosphere. The mole fractions of the individual products in the pyrolysis gas mixture are described as a function of time. Results show that NiCT appears to produce more N2O, NH3 and HONO upon flash pyrolysis, thus secondary oxidation reduction reactions may take place to a certain extent during its thermal decomposition, which in turn leads to unsteady combustion and possibly to failure of the device. While H2O and CO2 are the major two gas products of flash pyrolysis of MnTC, it warrants further in-depth trials for the adoption in detonators as eco-friendly and chemically compatible primary explosive. The two compounds both liberate volatile metal carbonate, oxide and isocyanate compounds.
