The reduction of I 2 by 1-hydroxyalkyl radicals in aqueous solution. A pulse radiolysis study

Abstract

The one electron reduction of iodine by various 1-hydroyalkyl radicals in aqueous solution is described, which leads first to the formation of I 2 −, and to I − at longer times. Rate constants of 5×10 9, 6.5×10 9, or 8×10 9 dm 3 mol −1 s −1 were obtained for the reaction between iodine and the radical of methanol, ethanol or 2-propanol, respectively.
