Abstract

The radiation induced hydrogen abstraction from hydrogen-containing substrates, by CF₂Cl radical was studied in CF₂Cl₂ solution as a function of the RH concentration (where RH is cyclohexane, cyclohexene, and ethanol) and as a function of temperature in the range of -80 to +20°C. For the CF₂Cl₂-ethanol system it was found that the ratio between the concentration of the abstraction product CHF₂Cl and the square root of the concentration of the recombination product (CF₂Cl)₂ is linearly dependent on the ethanol concentration (as was expected). However, for the two other systems, no dependence was found between this ratio and the concentration of the hydrogen containing substrate. A new mechanism for explaining those results was suggested.
