Abstract

Thermal decomposition of the energetic ionic liquids 1-methyl-4-amino-1,2, 4-triazolium iodide (Me4ATI), 1-methyl-4-amino-1,2,4-triazolium nitrate (Me4ATN), 1-amino-3-methyl-1,2,3-triazolium iodide (Me1ATI), and 1-amino-3-methyl-1,2,3-triazolium nitrate (Me1ATN) was studied by confined rapid thermolysis. Sub-milligram quantities of the compounds were subjected to decomposition under isothermal conditions achieved by initially heating the sample at rates of approximately 2000 K/s. The products formed by decomposition under the afore-mentioned conditions were sampled by rapid scan FTIR spectroscopy and time-of-flight mass spectrometry. Decomposition studies involving the iodide salts were carried out around 270-290.C, whereas the nitrate salts were subjected to 320-340.C. The amino group was found to be involved in the initiation reaction, forming copious quantities of ammonia from the iodide compounds and, N2O and H2 O from the nitrate compounds. The extent of decomposition of the triazole ring was minimal at the considered temperatures.
