PHOTOLYSIS OF ETHYL CHLORIDE AT 121.6-NM

Abstract

The photolysis of ethyl chloride at 121.6 nm was studied over the pressure range 60-4000 Pa at room temperature using a hydrogen atom resonance lamp. The pressure effect was investigated with CO2 and SF6. The scavenger effect of the reaction was also observed by adding NO gas. The major products of the reaction were CH4, C2H2, C2H4 and C2H6. The branching ratios between the elimination and the radical processes were found to be 0.68-0.32. The fraction of hot ethylene (above the critical energy) was found to be about 30%.
