ResumoAbstract The thermal decomposition of tetryl was studied in an accelerating rate calorimeter using spherical titanium and Hastelloy C bombs. Two decomposition peaks were observed. Three methods for the derivation of the activation energy for decomposition from the data were evaluated. The methods were in good agreement and gave values of 52 ± 1 kcal mol −1 for the first peak and 43 ± 1 kcal mol −1 for the second peak, for the decomposition in the Hastelloy C bomb. The values obtained from the decomposition in the titanium bomb were about 3 kcal mol −1 lower. Activation energies measured by techniques using increasing temperature are compared with those measured isothermally and reasons for the differences are discussed.
