Abstract:

The electrochemical behavior of nitromethane were studied by cyclic voltammetry and in situ FTIR technique in the room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluorobrate(BMImBF4) on a copper disk electrode. The influences of temperature and scan rate on the electrochemical characteristics of nitromethane were also investigated. Results show that the electroreduction of nitromethane in BMImBF4 is an irreversible process, which is controlled by diffusion. Finally nitromethane is reduced into trans-dimer of nitrosomethane in BMImBF4.

Key words: Nitromethane; 1-Butyl-3-methylimidazolium tetrafluorobrate; in situ FTIR; Electroreduction
