“…Protection of steel-based materials against acidic corrosion is a crucial issue for a wide range of industrial applications, as they are frequently used as a functional and structural material. , Although mild steel (MS) is cheap and has good mechanical properties compared to other metals, they are extremely sensitive to acidic media . The MS is more exposed to acidic solutions than alkaline and neutral environments in the petroleum and gas industry, thus degradation and structural failures are the serious consequences of its corrosion. , Hydrochloric acid (HCl) is extensively used in several applications such as acid fracturing, acid pickling, well acidizing, chemical cleaning, and water treatment.…”

The feasibility study of utilizing sunflower oil as renewable biomass source to develop highly effective inhibitors for mild steel corrosion (MS) in the 15% HCl medium was done by weight loss, potentiodynamic polarization (PDP), dynamic electrochemical impedance spectroscopy (DEIS), and electrochemical impedance spectroscopy (EIS), supported with energy-dispersive X-ray (EDX), atomic force microscopy (AFM), and field-emission scanning electron microscope (FESEM) techniques. Moreover, a complementary theoretical investigation was carried out to clarify the inhibition mechanism of inhibitors by density functional theory (DFT), density functional based tight-binding (DFTB), and molecular dynamics (MD) simulation approaches. The obtained results confirm that sunflower-oil-based corrosion inhibitor (SFOCI) has a significant anticorrosion property toward the dissolution of MS in 15% HCl solution in the temperature range 20–80 °C. In addition, the results show that SFOCI could provide an inhibition efficiency of 98 and 93% at 60 and 80 °C, respectively. The inhibition mechanism of SFOCIs was mixed-type and their adsorption on the surface of MS was mainly chemisorption. The FESEM and EDX studies proved the presence of SFOCI molecules on the surface of MS. In addition, the adsorption energy of SFOCI indicated an intense interaction between the inhibitor and surface of Fe. The results of this study could open a new window for the design and development of scalable and effective eco-friendly vegetable-oil-based corrosion inhibitors for highly corrosive solutions at high temperatures.

“…According to the result, it is evident that the inhibition efficiency increased with the increase of EFB-H dosage. This indicates that more inhibitor molecules are adsorbed at higher dosages, providing better surface coverage and better inhibition performance [60].…”

“…Lower corrosion current density is preferred upon addition of inhibitor as it indicates a lower corrosion rate. Based on the result, the reduction of current density and corrosion rate reflects that the inhibitor molecules were adsorbed on the mild steel surface and retarded the electrochemical reactions [60]. Hemicellulose components such as xylose, arabinose and glucose are among the inhibitor molecules adsorbed.…”

This study aims to develop a controlled release oil palm empty fruit bunch hemicellulose (EFB-H) inhibitor tablet for mild steel in 1 M HCl. As plant extracts tend to deteriorate at longer immersion time, limiting its industrial applicability, we attempted to lengthen the inhibition time by forming a controlled release inhibitor tablet. Electrochemical methods (potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)) were employed to investigate the efficiency and mechanism of the inhibition. An optimum dosage and immersion time was determined via Response Surface Methodology (RSM). EFB-H tablet was formulated using D-optimal mixture design, and its anticorrosion action at extended immersion time was compared with EFB-H powder. PDP measurement revealed that EFB-H is a mixed type inhibitor. RSM optimization unveiled that the optimum point for a maximum inhibition efficiency (87.11%) was at 0.33 g of EFB-H and 120 h of immersion time. Tablet T3 with EFB-H to gum Arabic to hydroxypropyl methylcellulose ratio of 66:0:34 portrayed the best tensile strength (0.243 MPa), disintegration time (152 min) and dissolution behavior. EFB-H tablet exhibited a longer-lasting inhibition effect than powder, which was 360 h as compared to 120 h for powder. Overall, EFB-H tablet has been successfully developed, and its enhanced effective inhibition time has been experimentally proven.

“…Di-BQC and MDi-BQC also performed effectively in 12 wt% HCl +3 wt% HF mixture at 90 • C. After 4 h of immersion, corrosion rate was reduced from 1104.98 g m − 2 h − 1 to 2.10 g m − 2 h − 1 and 2.07 g m − 2 h − 1 , respectively and the N80 steel surface was protected by 99.81%. Paul et al (2020) investigated the effectiveness of synthesized (E) -5-amino -3-(4-methoxyphenyl)-N ′ -(1-(4-methoxyphenyl) ethylidene) (-1Hpyrazole-4-carbohydrazide (AMPC) and (E) -5-amino--N ′ -(4-chlorobenzylidene) -3-(4-chlorophenyl)-1Hpyrazole-4-carbohydrazide (ACPC) on mild steel corrosion prevention in a 15 wt% HCl solution. The synthesis scheme is given in Scheme 2.…”
