Abstract

Flash pyrolysis of (CHZ)₂TNR and (SCZ)₂TNR was conducted by T-jump/FTIR spectroscopy under 0.1 MPa Ar atmosphere. The results show that eleven IR-active gas products obtained during flash pyrolysis process of the two title compounds are NO, CO, HCN, NH₃, NO₂, N₂O, HNCO, HNO₂, CO₂, H₂O and HCHO, of which NO and CO are the main gas products. The molar fraction of the individual product in the pyrolysis gas mixture was described as a function of time. At least some of the NO₂, N₂O and H₂O can result from the oxidization reaction of NH₃ during flash pyrolysis of (CHZ)₂TNR. It can be concluded that the two compounds are not worthy of further in-depth consideration of the adoption in detonators as eco-friendly primary explosive, and should not be used as gas generation composition of automobile crash airbag system taking into account the toxicity.
