ADDITION OF TRICHLOROMETHYL RADICALS TO TETRACHLOROETHYLENE

The gamma‐radiation‐induced free‐radical chain reactions in liquid CCl4C2Cl4cC6H12 mixtures were studied in the temperature range of 363–448°K. The main products in this system are chloroform, hexachloropropene and chlorocyclohexane. These products are formed via reactions (1)–(5): (Formula Presented.) with G values (molec/100 eV) of the order of magnitude of 102 and 103 at the lowest and highest temperatures, respectively. Values of k2/k1 were determined from the product distribution. In turn, these values gave the following Arrhenius expression for k2/k1 (θ = 2.303RT, in kcal/mol): (Formula Presented.) From this result and the previously determined Arrhenius parameters of reaction (1), k2 is found to be given by (Formula Presented.) . Copyright © 1979 John Wiley & Sons, Inc.
