Abstract
The kinetics of bimolecular decay of α-tocopheroxyl free radicals (T .) was studied by ESR mainly in ethanol and heptanol solvents. A second-order kinetic law was observed during the whole course of reaction (-d[T .]d t = 2 k[T .] 2) and the following rate constants were determined with good accuracy in the temperature range 281–321 K: ethanol: log(2 k) = 8.2 ± 0.5 — (6.6±0.7 kcal/mol)/(2.3 RT) M −1·s −1; heptanol: log(2 k)=6.1±0.4-(4.3±0.6 kcal/mol)/(2.3 RT) M −1.s −1. The global rate constant clearly increases with solvent polarity.
