Abstract
Aerial oxidation of ethanol in the presence of an aromatic azo-compound and CoX2(X = F, Cl, O2CMe, or ClO4) or iron(III) chloride gives a stoicheiometric amount of acetaldehyde with CoCl2, Co[O2CMe]2 and FeCl3 but no oxidation occurs with CoF2 and Co[ClO4]2. Addition of nitrogen-donor ligands promotes the oxidising activity in CoF2, and this effect is discussed and a mechanism is proposed for the oxidation. The cobalt(II) chloride–aromatic azo-compound combination effects slow catalytic oxidation of a potassium propionate–propanol mixture. Several rhodium comolexes which catalytically oxidise ethanol are reported, and 5% Rh–C dehydrogenates ethanol smoothly at its boiling point.Keywords
