✦ Synopsis

Tile polycyclic hydrocarbon content o/ products fr~mz reversed diffusion [lames o[ methane and ethylene, and from the pyrolysis of acetylene have been eo:amined; twenty compounds have been identified and determined. A high degree o/ similarity hetween tile qualitative compositions of the polycyclic hydrocarbon [ractions of the products was found. The experimental evidence is discussed with re]erence to the mechanism o/ carbon formation in diffusion flames. It is suggested that acetylene may he the precursor o/ the polyeyclic hydrocarbons, but it is shown that pyrolysis almte is not responsible for carbon formation, and that oxygen intervenes either in the pyrolytic or in other reactions.
