Summary
FeIII in H2SO4 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 orders with respect to [FeIII] and [carbohydrate] are unity. The oxidation rate decreases as [HSO4/−] and [H2SO4] increase. A plausible mechanism is proposed involving participation of an [FeIII-phen] precursor and sugar in the rate-determining step.
