The oxidation kinetics of propan‐1‐ol by alkaline hexacyanoferrate(III) catalyzed by ruthenium trichloride were studied spectrophotometrically. The initial rate method was used for kinetic analysis. The reaction rate shows a fractional order in [oxidant] and [substrate] and a first‐order dependence on [RuCl 3 ]. The dependence on [OH − ] is complicated. A reaction mechanism involving two active catalytic species is proposed. Each one of these species forms an intermediate complex with the substrate. The attack of these complexes by hexacyanoferrate(III) in rate‐determining step produces a radical species which is further oxidized in the subsequent step. © 1997 John Wiley & Sons, Ltd.
