Abstract

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.
