    Evaluation of the inhibition performance of piperazine-based polyurea towards mild steel corrosion: The role of keto-enol tautomerization by Abdulazeez, Ismail

    Published 2022
    “…Herein, we have synthesized a new piperazine-based polyurea inhibitor (PUCorr) which is readily soluble in water through dispersion in N-methyl-2-pyrrolidone for mild steel corrosion. The inhibitor exhibits a sufficient protection of the surface of mild steel via an intra-molecular keto-enol proton transfer mechanism leading to the formation of the Fe-PUCorr complex. …”
