Abstract

The dose rate dependence of CF2 Cl2 decomposition was studied in both, gas and liquid phase, for the range of 2.95·101 7–1.9·101 9 eV·g−1·h−1. The major products were found to be CF3Cl, CFCl3, CF2Cl−CF2Cl and CF2Cl−CFCl2. The decomposition of CF2Cl2 was found to decrease with decreasing dose rate for the liquid phase, while an opposite trend was found for gas phase radiolysis. A new mechanism which explains these contrasting findings was suggested. The contribution of radical and of ionic (or molecular) processes to the yields of the various products was estimated.
