Results of γ-radiolysis experiments with deaerated aqueous solutions of difluorochloromethane have shown that the initial reaction occurs via the attack of hydrated electron on this solute, to produce chloride ions and difluoromethyl radicals. A rate constant of <tex-math>$2.9\pm 0.8\times 10^{9}\ M^{-1}\ {\rm sec}^{-1}$</tex-math> was measured for the hydrated electron reaction. It has been found that difluoromethyl radicals undergo secondary dimerization and hydrolysis reactions. The product of the dimerization reaction has been identified as tetrafluoroethane, whereas the hydrolysis reaction leads to the formation of carbon dioxide and fluoride ions. A dose-rate dependence has been observed for the products of secondary radical reactions.
