Oxidation Of Ethanol

The oxidation of ethanol by Fenton's reagent was studied to confirm the validity of the redox titration procedure. A quantitative analysis of oxidation products during the complete oxidation of ethanol and its consecutive oxidation products is presented. � The oxidation of t-butyl alcohol was studied under a number of different conditions and yields of acetone and the dimer, 2,5- dimethylhexane-2,5-diol, were obtained. The effects of oxygen, copper salts, and chloride and bromide ions on this oxidation were studied. ��� The ratio of reaction rates of ethanol and t-butyl alcohol with the free hydroxyl radical was determined.

H2o2 System

The effect of complex formation on the oxidation of substrate in the Fe2+-H2O2 system has been studied. t-Butyl alcohol which is normally oxidized to the dimer, 2,5-dimethylhexane-2,5-diol, by Fenton's reagent has been used as a probe for the presence of free hydroxyl radical. ��� It is shown that when suitable complexes are formed substrates are not oxidized by free hydroxyl radical. Instead, new mechanisms involving one- and two-electron transfers within a substrate-ferrous ion-peroxide complex are proposed.

Fenton's Reagent

Oxidations using Fenton's reagent have not been followed previously by redox titration. This procedure assists in defining the overall reaction and allows both an estimate of relative rates of oxidation and a measure of the consumption of peroxide by the organic substrate. The peroxide consumed in the complete oxidation of substrate to inactive compounds has been measured by titration at constant oxidation potential. Such measurements reflect the peroxide consumed by the substrate and its consecutive oxidation products and may therefore be used to assess the significance of oxidation pathways.

Effect Of Oxygen

The effect of oxygen on oxidations by Fenton's reagent has been studied by redox titration at constant oxidation potential. The reactivity of substrate radicals towards oxygen has been assessed. The peroxide requirements for the complete oxidation of substrate in the absence and presence of oxygen have been compared. The extent of oxidation of different substrates was determined by gas chromatography and the results indicated the occurrence, in oxygen, of nem chain reactions.

Polyhydroxy Compounds

The oxidation of carbohydrates and some other polyhydroxy compounds by Penton's reagent has been studied by redox titration at constant oxidation potential. Such compounds were oxidized by a cyclic process involving the formation of enediols which reduced ferric ion. The possible significance of these reactions is indicated. The peroxide consumed in the complete oxidation of carbohydrates and some polymers was measured in the absence and presence of oxygen.
