Abstract

The kinetics of the reactions of hydrogen atoms with aliphatic alcohols in aqueous solution were studied by pulse radiolysis. The rate constants for the reaction of hydrogen atoms with methanol, ethanol, 2-propanol and tert-butyl alcohol were determined from the increase in optical absorption in the UV region to be 1.1 × 106, 1.75 × 107, 5.3 × 107 and 2.3 × 105 dm3 mol−1 s−1, respectively. The bimolecular decay rate constants of the first two alcohol radicals were evaluated to be 2.4 × 109 and 1.5 × 109 dm3 mol−1 s−1.
