✦ Synopsis

At 30°C butadiene is only partially oxidized on Pt and Au anodes in HzS04-Na2S04 solutions. On Pt, ethanol is the principal resulting substance at this temperature. On Au, tert-butyl alcohol and propanone are obtained at 30°C and a hydroxylated polymer, together with butanone, are produced at 70°C.

Polarization curves run at this temperature and at 30°C allow some mechanistic conclusions: on F't electrodes the role of surface must be recognized in analyzing this kind of reactions ; on Au, it is suggested that hydration of butadiene must take place homogeneously prior to adsorption of the organic molecule.

The stability of the surface of a polycrystalline electrofacetted Pt electrode was studied in nitromethane (NM). It was observed that if the electrode was transferred from aqueous solution into NM and back without electrochemical polarization being applied in NM, the surface showed the same hydrogen
