The combustion chemistry of morpholine (1-oxa-4-aza-cyclohexane) was investigated under laminar, premixed low-pressure conditions. Morpholine, as a heterocyclic secondary amine with numerous industrial applications, was studied as a model fuel which simultaneously contains oxygen and nitrogen heteroatoms. Stable and radical intermediates and products of the combustion process in a slightly fuel-rich {phi} = 1.3 (C/O = 0.41) flat premixed morpholine-oxygen-argon flame at 40 mbar (4 kPa) were identified. A detailed fuel destruction scheme is proposed based on combined measurements using two different in situ molecular beam mass spectrometry (MBMS) techniques. The results are discussed with special attention to hydrocarbon, oxygenated and N-containing compounds important in pollutant emission.
