Howard, J B

The chemistry of heavy aromatic compounds in fuel-rich flames involves numerous intermediate species whose sequential formation and destruction give a progression to decreasing amounts of increasingly heavy species, leading eventually to soot if the fuel/oxygen ratio is high enough. The combined presence of aromatic radicals, unsaturated aliphatics such as acetylenic species and H atoms is particularly favorable to molecular weight growth. When the initial fuel contains no aromatics, mechanisms controlled by butadienyl radical reacting with acetylenic species can form single-ring aromatics at rates consistent with observed values.
