“…Persea schiedeana Nees’s case has not been analyzed still as a corrosion inhibitor alternative. Even so, a few analyses were done by some authors, reporting that its chemical compositions found the presence of Fatty acids such as Oleic acid and Palmitic acid, as phenolic and antioxidant activities had been reported 12 – 14 . Then, most studies have been conducted to evaluate the nutritional value of the PSN or its agro-industrial potential to increase its production 15 .…”

The hexane extract of Persea schiedeana Ness (PSN) was analyzed as corrosion inhibitor for the brass surface immersed in 0.5 M HCl. Fourier-transform infrared spectroscopy and a gas chromatographic (GC) and mass spectrometric (MS) were used to identify the PSN extract’s functional groups and compound constituents. The functional groups identified were $${\text{C}}{\text{H}}_{3}$$ CH 3 and $${\text{C}}{\text{H}}_{2}$$ CH 2 functional alkyl groups, $$\text{C=O}$$ C=O stretching vibration of aldehydes, ketones, and carbonyl groups. The GC/MS determined the presence of fatty acids in the PSN extract, where palmitic acid, oleic acid, and ethyl oleate were the major constituents. Electrochemical characterizations were conducted to observe the effect of PSN as corrosion inhibitor on the brass surface. The Rp and Rn calculated from EIS and ENA give the same behavior. Based on the OCP behavior, it was determined that the PSN works as a mix inhibitor, affecting both anodic and cathodic reactions. The corrosion current density (Icorr) suggests that the extract of PSN reduces the corrosion rate of the brass with efficiencies above 90% for all concentrations. The efficiency obtained for each PSN concentration was attributed to forming a corrosion scale of $${\text{CuO}}$$ CuO and $${\text{C}}{\text{u}}_{2}{\text{O}}$$ Cu 2 O , which reacted with the carboxyl group to form copper carboxylates on the metal surface.

The hexane extract of Persea Schiedeana Ness (PSN) was analyzed as corrosion inhibitor for the brass surface immersed in 0.5 M HCl. Fourier-transform infrared spectroscopy and a gas chromatographic (GC) and mass spectrometric (MS) were used to identify the PSN extract´s functional groups and compound constituents. The functional groups identified were CH3 and CH2 functional alkyl groups, C = O stretching vibration of aldehydes, ketones, and carbonyl groups found in flavonoids and fatty acids. The GC-MS determined the presence of fatty acids in the PSN extract, where palmitic acid, oleic acid, and ethyl oleate were the major constituents. Electrochemical characterizations were conducted to observe the effect of the hexane extract of PSN as corrosion inhibitor on the brass surface. The Rp and Rn calculated from EIS and ENA give the same behavior with magnitude values near each one. Based on the OCP behavior, it was determined that the PSN works as a mix inhibitor affecting both anodic and cathodic reactions. The corrosion current density (Icorr) determined with the Potentiodynamic test suggests that the extract of PSN reduces the corrosion rate of the brass with efficiencies above 90% for all concentrations. The efficiency obtained for each PSN concentration was attributed to forming a corrosion scale of CuO and Cu2O, which reacted with the carboxyl group to form copper carboxylates on the metal surface.
