Abstract

Abstract: Catalytic levels of fully reduced 5methylphenazinium (MPH) and metal ions induce a chain decomposition of H202 in N,-saturated aqueous benzoic acid solution, with concomitant production of 0-, m-, and p-hydroxybenzoic acids. The oxidant inducing the aromatic hydroxylations is the hydroxyl radical, produced in a one-electron, metal ion mediated reduction of H202. The rate of decomposition is zero order with respect to [H202 ...
