Thermal decomposition of hexahydro‐1,3,5‐trinitroso‐s‐triazine (TRDX), C 3 H 6 N 3 (NO) 3 , and hexahydro‐1,3‐dinitro‐5‐nitroso‐s‐triazine (MRDX), C 3 H 6 N 3 (NO 2 ) 2 (NO), was studied by DTA and TGA in argon atmosphere, which was showing overall first‐order kinetics. The results are compared with those for RDX in order to determine the effect of replacing > NNO 2 group with > NNO. The decomposition of the admixture of RDX/TRDX (50/50 by weight) was also tested. The kinetic parameters calculated are: for RDX, ln k = 43.1–47,900/RT, for MRDX ln k = 34.3–37,200/RT, for TRDX ln k = 29. 4–30,500/RT, while for the RDX/TRDX admixture, ln k = 37.0–39,700/RT, where k is in s −1 . The melt phase decomposition products of RDX, MRDX, and TRDX condensed on a NaCl plate which was placed 2 cm above the sample cell were almost exactly the same in IR measurements. RDX is soluble in liquefied TRDX and the decomposition of RDX is accelerated by its liquefaction.
