Popis:	This paper describes the investigation of the thermal decomposition of 1,4-butanediammonium dinitrate (BDD). Analytical techniques used for this work were differential scanning and accelerating rate calorimetry, thermogravimetry, tandem gas chromatography/mass spectrometry and high performance liquid chromatography. It was shown that BDD decomposes thermally from the molten state via a multistep process that produces a variety of condensed phase and gaseous products. The nature of the products suggest that a proton transfer reaction from cation to anion followed by C-N bond rupture occurs early in the decomposition process. The presence of early heterocyclic reaction products demonstrates that one of the reaction mechanisms involves cycloelimination. Later reactions appear to be competitive and may proceed through transient, primary nitramine and nitrosamine species.
