Abstract

The dependence of the yields of products in the γ-radiation-induced free-radical reactions in carbon tetrachloride solutions of secondary alcohols on the alcohol concentration and temperature was studied in the range of 0.05-0.6 M and 30-150°C. The rate constant for the reaction CCl3 + R1R2CHOH → CHCl3 + R1R2COH (k1) was found as log k1 (M-1 s-1) = 8.63 - 9.1/θ, where θ = 2.303RT kcal mol-1. The activation energy is 1.8 ± 0.3 kcal mol-1 lower than for secondary hydrogens in alkanes and about the same as for the tertiary hydrogens in 2,3-dimethylbutane.
