Title: The destruction chemistry of organophosphorus compounds in flames -- II: Structure of a hydrogen-oxygen flame doped with trimethyl phosphate

Abstract

Molecular beam mass spectrometry with electron-impact ionization at 12.9--21 eV and an electron energy spread of {+-}0.25 eV was used to study the structure of a premixed H{sub 2}/O{sub 2}/Ar(o.26/0.13/0/61) flame without additives and with 0.2 vol % of the additive trimethyl phosphate (TMP), when stabilized on a flat-flame burner at 47 Torr. Stable components (H{sub 2}, O{sub 2}, H{sub 2}O), atoms, and radicals (H, O, OH) were found, as well as organophosphorus compounds including TMP and some intermediates of its destruction. Using measured intensity profiles of all the flame species and their calibration coefficients, their mole fraction profiles, including those of atoms and free radicals, were measured. The calibration coefficients for some species were determined experimentally; others were estimated. The previously suggested mechanism of destruction of TMP in H{sub 2}/O{sub 2}/Ar flames is refined.
