VAPOR-PHASE RADIOLYSIS OF CYCLOHEXANE AND MIXTURES OF BENZENE AND CYCLOHEXANE

Abstract
The vapor-phase radiolysis of cyclohexane and benzene-cyclohexane mixtures has been studied with isotopic tracer techniques using C6D12 and C6D6. Benzene does not quench the molecular detachment of hydrogen, [Formula: see text] but interacts with the second-order processes giving HD in C6D12–C6H12 mixtures. This interaction is not H-atom scavenging and an ionic mechanism is preferred. The radiolysis of all these systems is very different from their liquid-phase radiolysis.
