Radiation-induced Nitration of Aliphatic Hydrocarbons

THE behaviour of fission product iodine in a tributyl phosphate–kerosene system for reprocessing pile-irradiated uranium fuels has recently been studied in this laboratory. It was found that the principal mode of fixation of iodine in the hydrocarbon diluent was scavenging by hydrocarbon radicals produced by the action of the fission product radiation. However, it was observed that the G-value for fixation under process conditions was only about 0.1. This is very much lower than the values of about 7.0 reported for air-free n-heptane1 and 5.6 for air-free cyclohexane2, which are generally accepted as giving some indication of the total yield of radicals in irradiated aliphatic hydrocarbons.
