The radiolysis of mixtures of CF2Cl2 with RH substrates
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.
