The results have shown, in presence of stirring, that the electrochemical behaviour of the 2-methylfuran is similar to furan, but it is different to 2,5-dimethylfuran. IR spectrum of the anodic deposit from the 2-methylfuran or furan show the presence of tetra-n-butylammonium perchlorate and the opening ring product in the film, which is strongly adsorbed on the electrode. The supporting electrolyte probably interferes in the formation of well-organized organic film. Also, others contaminants, such as oxygen and water which are inevitably present in solution affect the mechanism of oxidation and contribute to the structural film.} }
