Single Pulse Shock Tube Study on Decomposition and Incipient Detonation of the Trinitrotoluene

Dilute quantities of o-nitrotoluene and anthranil have been pyrolyzed in comparative rate single pulse shock tube experiments. Rather a lot of CNO2 bond cleavages than NO2 isomerization are found as major channels in p-nitrotoluene decomposition. We demonstrate that the important pathway for pyrolysis involves the formation of anthranil with the following overall rate expression: k(o-nitrotolueneanthranil) =1.21013exp (-26 020/T) s-1. The anthranil that is formed is very unstable under our conditions, the rate expression for disappearance has been found to be the following: k(Anthranil)d＝3.71015exp(－25 800/T) s-1.
