The kinetics of the initial stage of thermal decomposition of N-2,4,6 tetranitro-N-methyl aniline (tetryl) in condensed state has been investigated by high temperature infrared spectroscopy (IR) in conjunction with pyrolysis gas analysis and thermogravimetry (TG). The decomposition in KBr matrix in the temperature range of 131 to 145 °C shows rapid decrease in the N-NO2 band intensity as compared to the C-NO2 band. Decomposition products in the initial stage show mainly NO2 gas and picric acid. The studies show that the initial stage of decomposition of tetryl occurs by the rupture of the N-NO2 bond and the energy of activation for this process is 177 kJ/mol.
