It is well known that the burner gas formed by the incomplete combustion of methane contains many kinds of higher olefins the great part of which are the homologues of acetylene.But few report has been published concerning their details.Though little attention has been made to these materials in the fundamental study, because their content is too small to attract our interest in view of material and heat balances, it is very useful to know their behavior for enlarging of this process to an industrial scale, especially the purification process of acetylene.
The authors examined them by mass spectrometer and ultra-violet analysis, and identified the existence of the following six components.
Methylacetylene, vinylacetylene, vinyldiacethylene, phenylacetylene, benzene, diacetylene or methyldiacetylene.
Regarding benzene, this compound is probably formed by the trimerisation of acetylene, and we accordingly included it in the group of higher acetylenes.
