✦ Synopsis
Mass spectrometry and absorption spectroscopy have been used to measure the concentration profiles of most of the species appearing in a slightly rich CH4/O 2 low pressure flame doped with Nil 3. The mole flux profiles of these species and the net reaction rate profiles of the reactions producing NO or N 2 from NH 3 have been derived. The data lead to the following conclusions: a. The reactions H H I H20 NH 3 + -~ NH 2 + LH2 and E7 [H O NH 2 + --, NH + /H2 are not in equilibrium if the JANAF value of AHf(NH) is used in the calculations. If the value of Kaskan and Nadler I 1 ] is used, the last reactions appear to be equilibrated. b. The HCN-q2N system is in partial pseudoequilibrium near the flame front. c. The measured NO yield is in good agreement with De Soete's [2] empirical correlation. d. In the flarne zone Nil 3 is transformed to HCN or N 2 by the reaction sequence
