Abstract
The new data for corrosion of carbon steel are reported in aqueous mixed solution containing (0.1-1.0 M) 1-Butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]), (0.1-1.0 M) 1-Butyl-3-methylimidazolium dicyanamide ([bmim][DCA]) and 4M monoethanolamine (MEA) at 60 ◦C and CO2 loading 0.55 mol/mol using electrochemical techniques; which were impedance spectroscopy and polarization curves. The experimental results show that the corrosion of carbon steel decreased with increasing concentrations of both ([bmim][DCA]) and ([bmim][BF4]) from 0.1-1.0 M. Also the surface analysis scanning electron microscopy (SEM) was carried out to characterize the corrosion products layers on the metal surface. Ionic liquids with dicyandiamide anion provided a better protection than tetrafluoroborate. These results suggest that the nature of the anion of ILs have influence on the corrosion of carbon steel.
