摘要: Abstract A comparative study of metal corrosion in a protic ionic liquid (PIL) and an aprotic (AIL) with the same anion is reported this paper. The stability Ni, Cu, Al, Zn, Mg 1-butylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([BPyr] [NTf 2 ]) PIL 1-butyl-1-methylpyrrolidinium ([BMPyr] AIL evaluated, measured potential (E corr ) current density (i these metals both liquids are compared. Electrochemical tests show that has narrower electrochemical window generally more reactive toward than AIL. Even though observed behavior or less similar liquids, parameters obtained reflect fact presence proton on cation makes susceptible to corrosion, i.e. produces lower E higher i .
