Synthesis of Ethyl N-imidazolyl acetate and Its Inhibitory Action
Abstract:
Ehyl N-imidazolyl acetate (IEA) was synthesized from imidazole and ethyl chloro acetate and characterized by IR spectrum.The corrosion-inhibition function of IEA towards copper in Na2SO4 and NaHCO3 solutions were examined by polarization curves and AC impedance measurements.The results revealed that in 5 mg/L solution of 3% (mass fraction) NaHCO3 or Na2SO4 at 15℃ IEA showed an inhibition efficiency of 86.8% and 92.7%,respectively,towards copper electrode.IEA had lower use level and better corrosion-inhibition efficiency than imidazole.
