✦ Synopsis

The tendency of various single-component hydrocarbons to release soot from a laminar diffusion flame was investigated using experimental results obtained by the authors and other investigators. The hydrocarbon compounds considered include alkanes, alkenes, alkynes, aromatics and polyaromatics. It was found that the structure of hydrocarbon molecules is one of the principal factors governing their sooting tendency in laminar diffusion flames. The ring is by far the most important molecular or submolecular structure and fused cyclic molecules are the most prolific sooters. In the case of non-aromatic hydrocarbons, secondary structural influences that tend to increase the sooting tendency are the length of the main chain or ring circumference (in terms of carbon atoms) and the number, position and length of side-chains.
