The reaction was investigated in the gas phase over the range 80–225°C using the photolysis of heptafluoroisopropyl iodide as the source of radicals. The rate constant, based on the value of 1013.36 cm3 mol?1 s?1 for the recombination of i-C3F7 radicals, is given by where θ = 2.303 RT/cal mol?1. Arrhenius parameters for chlorine abstraction from CCl4 by CF3, C2F5, n-C3F7, and some hydrogenated radicals are compared.
