## Abstract The kinetics of oxidation of several substituted quinols by a series of Tris(1,10‐phenanthroline)iron(III) complexes has been investigated with a stopped‐flow technique at 6.0 and 20.0°C. The reactions were found to be first order on both reactants and independent of acidity. The second
Fe uI in H2SO~ medium does not oxidize sugars even at the reflux temperature, however, the reaction is catalysed by trace amounts of 1,10-phenanthroline (phen). A kinetic study shows that the oxidation rate increases as [phen] increases and exhibits a fractional order dependence upon [phen]. The ord
Iron(III)-1 ,10-phenanthroline complex obtained, in situ, by direct mixing of iron(II1) and 1 , 1 0-phenantbroline, oxidizes V(N). The reaction is markedly accelerated by sodium dodecyl sulphate. The rate-[surfactant] profile exhibits a maximum. The kinetic analysis of the micellar effect has been
The kinetics of the oxidation of 1,10-phenanthroline (1,10-phen) by permanganate were investigated in alkaline medium. A first-order, fractional-order and zero-order dependence of the rate each in [MnO 4 À ], [1,10-phen] and [OH À ], respectively, was observed. The data suggest that the oxidation pr
