Relationships between flow reactor derived chemical mechanisms and the macroscopically observed sooting tendencies in premixed and diffusion flames are developed. In particular, the impact of elements of the mechanism for the oxidation of benzene/phenyl radical on the inhibition of soot formation through the removal of a critical precursor is explored. Pyrolysis chemistry, especially those aspects altered by small amounts of oxygen, is related to the increased precursor concentration that is responsible for the augmented soot formation in ethene diffusion flames with oxygen added to the fuel stream. Flow-reactor data from ethene pyrolysis studies (with and without small amounts of added oxygen), demonstrating the enhanced production of acetylene and butadiene, are presented in support of some of the developed relationships between sooting phenomenology and chemical mechanisms.
