“The final publication is available at Springer via http://dx.doi.org/10.1007/s12678-013-0182-x” ; The electrochemical behaviour of o-cresol in acidic medium on platinum electrode has been studied by cyclic voltammetry and in situ Fourier transform infrared spectroscopy. The o-cresol suffers hydrolysis during oxidation giving rise to the formation of methyl-p-benzoquinone. In situ FTIR spectroscopic studies also reveal the presence of CO2, formed as a consequence of the rupture of the aromatic ring. Moreover, the oxidation of o-cresol in acidic medium produces a polymeric film on the platinum surface that precludes further oxidation of o-cresol. The reduction of o-cresol at potentials below 0 V produces in the first step the partial reduction of the aromatic ring and when the potential goes to values below 0 V, methyl-cyclohexanone. ; Ministerio de Economia y Competitividad ; FEDER [MAT2010-15273] ; Generalitat Valenciana [PROMETEO/2013/038] ; Taleb, Z.; Montilla, F.; Quijada Tomás, C.; Morallón, E.; Taleb, S.
