离子液体BMIMBF4中对甲氧基甲苯的电化学氧化

doi:10.3866/PKU.WHXB201112122

Abstract

Abstract: The electrochemical oxidation behavior of p-methoxy toluene was studied in an ionic liquid of 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF₄) on platinum electrode by cyclic voltammetry (CV), chronoamperometry (CP), and in situ Fourier transform infrared spectroscopy (in-situ FTIRS). The results showed that the electrochemical oxidation of p-methoxy toluene in BMIMBF₄ was irreversible. The four-electron process was controlled by diffusion, and the diffusion coefficient D was 3.4×10^-7 cm²·s^-1. The main oxidation product was anisaldehyde. A proper amount of water and a suitable temperature were favorable for the anisaldehyde.

Key words: Electrooxidation, p-Methoxy toluene, Anisaldehyde, Ionic liquid, In situ Fourier transform infrared spectroscopy
