Condensed-Phase Reactions of Energetic Ionic Liquids Under Different Ignition Stimuli

摘要

The experimental work conducted under this program was designed to provide new insight into condensed-phase reactions leading to ignition of ionic liquids. The objectives of the work were: (1) to identify the initiation and secondary reactions in the condensed phase that lead to ignition and combustion, (2) to understand the effects of the structure of the cation on these reactions, and (3) to determine the effects of the type of ignition stimulus used. Two primary experimental approaches were applied: laser heating coupled with tandem mass spectrometry and rapid thermolysis coupled with FTIR and time-of-flight mass spectrometry. The compounds studied included: l-Ethyl-3-Methyl-Imidazolium Nitrate, 4-Amino-l,2,4-Triazolium Nitrate, i-Methyl, 4-Amino-l,2,4-Triazolium Nitrate, 2-Amino-4,5-Dimethyl Tetrazolium Nitrate and 1-Amino-4,5-Dimethyl Tetrazolium Nitrate.
