Electron capture processes in the radiolysis of hydrogen chloride and of propane + hydrogen chloride mixtures

Abstract

The depression of the H₂ yield from irradiated HCl gas by SF₆ has been studied at different HCl concentrations. It is concluded that HCl reacts with thermal electrons, in competition with SF₆, by a process which is third order in HCl concentration. A mechanism is suggested for this process which also explains the effect of HCl on the N₂ and H₂ yields in the radiolysis of C₃H₈+N₂O mixtures.
