Abstract

The kinetics of the gamma‐radiation induced free‐radical chain reaction in solutions of carbon tetrachloride in n‐hexane (RH) was investigated in the temperature range of 297.5–373°K. Trichloromethyl radicals were produced by the reaction of radiolytically generated hexyl radicals with carbon tetrachloride. The kinetics of the following reactions were investigated:

The following rate expression was obtained:

where θ = 2.303 RT in kcal/mole. The error limits are the standard deviation from the least mean square Arrhenius plots. It is concluded that reaction (4) is diffusion controlled in the liquid phase, and that the activation energies in the gas and liquid phases of reaction (3) are equal.
