PROTECTION BY BENZENE IN THE RADIOLYSIS OF CYCLOHEXANE
Yields of atomic hydrogen from the radiolysis of cyclohexane-benzene mixtures by Co/sup 60/ gamma rays were measured using an iodine scavenger technique. Benzene affects the production of atomic hydrogen from cyclohexane by an energy transfer mechanism. The ratio of the rate constant for transfer of excitation to benzene from an excited cyclohexane to the rate constant of the reaction of such an excited species by the process that ultimately yields HI, was estimated to be 0.31 M/sup -1/. From examination of previous data, the ratio of the rate constant for transfer of excitation to benzene to the rate constant for the reaction of an excited cyclohexane that ultimately yields hydrogen by a process frequently assumed to be molecular. is calculated to be 0.65 M/sup -1/. It was concluded that the effect of benzene on the yield of hydrogen from a cyclohexane-benzene mixture is due to the energy transfer and hydrogen atom scavenging. (auth)
