Photolyse du chlorure d'éthyle gazeux en-dessous et au-dessus du potentiel d'ionisation

Abstract

Photolysis of gaseous ethyl chloride was performed at λ = 123.6 and 106.7–104.8 nm. There is no ionisation at 123.6 nm, while at 106.7–104.8 nm 40% of the absorbed light lead to ions. The identified products are the following: H2, CH4, C2H2, C2H4, C2H6, C3H6, C3H8, C4H10, CH3Cl, C2H3Cl, 2-C4H9Cl, 2,3-C4H8Cl2, and 1,3-C4H8Cl2. The effect of radical and electron scavengers on the product formation was studied. Charge neutralization reactions increase yields of H2, C2H2, and C2H4.
