Acetic acid the most prevalent organic acid contributes 50-90% of organic acids found in some produced fluids the oil and gas industry. A significant amount of research has been done that proves acetic acid enhances observed corrosion by accelerating the cathodic reaction. However very few researchers have investigated the mechanism of corrosion by acetic acid and the question remains as to whether there is a direct reduction of acetic acid at the metal surface or whether acetic acid is only a reservoir of hydrogen ions. The latter mechanism is termed the “buffering effect” as acetic acid may also dissociate in order to provide more hydrogen ions when those close to the metal surface are consumed by the corrosion reaction. This research focused on elucidating the acetic acid corrosion mechanism by using electrochemical techniques such as potentiodynamic sweeps and electrochemical impedance spectroscopy. The results show that at the same pH the charge transfer current and the charge transfer resistance are the same for different concentrations of acetic acid. This implies that there is no direct reduction of acetic acid at the metal surface leading to the conclusion that the only cathodic reaction which takes place at the surface is the reduction of hydrogen ions.
