Thermal decomposition of 2,4,6-trinitrotoluene in the temperature rang
e from 200 to 340 degrees C in melt and in solutions was studied. The
main features of the process (high initial rates, activation energies
lower than those in the gaseous phase, a higher acceleration at the ca
talytic stage, and the effect of nonpolar solvents on initial rates) a
re explained in terms of a kinetic scheme corresponding to a degenerat
e branched chain reaction.
