Abstract
The radiation chemistry of ethanol has been investigated by pulse radiolysis with emphasis on the decay kinetics and yield of the solvated electron, e−EtOH, in neutral and alkaline solution. Computer calculations show that the experimental data are most consistent with a yield G(e−EtOH) = 1.7 molecules/100 eV, and a pseudo first-order half life for e−EtOH, [Formula: see text] which corresponds to a second-order rate constant k(e− + EtOH) = 7 × 103 M−1 s−1.Rates of reaction of the electron with acetaldehyde and C6F12 have been determined to be 4.0 ± 0.5 × 109 and 2.5 ± 0.5 × 109 M−1 s−1, respectively.The empirical square root formula for spur scavenging kinetics[Formula: see text]is obeyed for scavenging of the radiation produced positive ion.
