Possibilities of applying the Piloyan method of determination of decomposition activation energies

Part III. Derivatives containing two picryl groups in the molecule, and melamine derivatives

Journal of Thermal Analysis and Calorimetry
Author: S. Zeman

Via the Piloyan method, activation energiesE were determined for polynitroaromatic compounds containing two picryl groups, and for melamine derivatives. At the same time the initial temperatures of exothermic decompositionT D were determined by means of non-isothermal DTA. Linear relationship were derived betweenE ·T D −1 and published kinetic data obtained from the study of HNB, HNAB, DIPS, DIPSO, HNS and TPM by isothermal manometry. On the basis of the derived relationship, as well asE andT D values from DTA measurements, kinetic data were calculated for DPA, KDPA, DMHNB, DPM, DPE and TMPM with the manometric method.
