Décharge triboélectrique dans les alcanes C1–C5 à basse pression

Abstract

The following gases were submitted to a triboelectric discharge: CH4, C2H6, C3H8, n-C4H10, iso-C4H10, and n-C5H12 and their decomposition products were analyzed. The proportion of unsaturated in the products is around 75% of the total. The total yield of decomposition products increases with the number of carbon atoms in the compound submitted to the discharge. The proportion of saturated products formed from methane increases with pressure. Tentative explanations are offered to elucidate the observed behaviour of gases in the tribodischarges.
