摘要：

The anticorrosive activity of furfural derivatives, by ex-situ and in-situ syntheses, on mild steel immersed in CO2- saturated formation water solution was evaluated using mass loss measurements, polarization curves, X-ray photoelectron spectroscopy, quantum chemical calculation, and electrochemical impedance. Furfural thio-semicarbazone presented inhibition efficiency reaching 90.2% for 72 h in immersion. The same molecule, synthesized in-situ by the mixture of the precursors in the corrosive medium, also produced good efficiency, 82.2% for 24 h of immersion, but it decreased over the time due to incomplete conversion of the precursors in furfural thiosemicarbazone.
