Abstract
Wide application of fullerene is expected in the various fields such as new materials and medical applications. Especially combustion synthesis process of fullerene is expected as one of mass production methods of fullerenes. However, the fullerene formation mechanism from PAHs in a flame has not been clarified yet. In the present study, PAH and fullerene concentration were investigated by gas and liquid chromatography in total amount of soot that was made from toluene flame burned at various temperature and pressure. Effects of pressure and equivalence ratio to the formation of the PAHs and fullerenes and branching mechanism between fullerene and soot were discussed.
