Electron scavenging by bromobenzene in the radiolysis of hydrocarbon solutions

Abstract

A quantitative study has been made of electron scavenging processes in -irradiated liquid hydrocarbons: n-pentane, cyclopentane, n-hexane, cyclohexane, 3-methylpentane, 2,3-dimethylbutane, 2,2-dimethylbutane, 2,2,4-trimethylpentane, and n-octane. The benzene yield observed upon electron scavenging by bromobenzene in the hydrocarbon solutions can be quantitatively described by an empirical model developed by Schuler and coworkers. The ion-pair yields and the reactivity parameters for electron scavenging were obtained by the analysis of data. The results indicate that the total ion-pair yields in liquid alkanes are about 4 and do not differ very much from the gas-phase values. The ranges of electrons in the hydrocarbons studied were also calculated based on a model in which a simple exponential distribution was assumed for initial electron-positive ion separation distances.

Effect of an external electric field on the yield of trapped electrons in a γ-irradiated hydrocarbon glass

“…Therefore, it seems reasonable to assess the value of G, in hydrocarbon glasses on the basis of the value of G, in hydrocarbon liquids. Although the value of G, in hydrocarbon liquids is not exactly known, it is considered to lie in the range 4-5 from several investigations (13)(14)(15)(16)(17)(18) reduces to the simple exponential distribution function for n -, co. The mean range, F, of thermalized electrons can be derived from eq.…”
