Description

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 to 0.6 M and 30 to 1500C. The rate constant for the reaction CCl3 + R1R2CH0H → CHCl3 + R1R2COH (k1) was found as log k1 (M-1s-1) = 8.63 - 9.1/theta, where theta = 2.303 RT kcal mol-1. The activation energy is 1.8 +- 0.3 kcal mol-1 lower than for seconday hydrogens in alkanes and about the same as for the tertiary hydrogene in 2,3-dimethylbutane
