“…Unlike some of the aforementioned inhibitors that experienced a reduction in inhibition efficiency at higher temperatures, MPO demonstrated an increase in inhibition efficiency with rising temperatures. This temperaturedependent behavior enhances its versatility, allowing for effective corrosion protection even in elevated-temperature environments [75,76]. Another advantageous characteristic of our inhibitor is its response to immersion time.…”

Corrosion is a pervasive challenge in various industrial applications, particularly in acidic environments. This comprehensive study delves into the effectiveness of 2-methyl-4-propyl-1,3-oxathiane (MPO) as a corrosion inhibitor for mild steel exposed to hydrochloric acid (HCl) solutions. The investigation employs weight loss techniques to assess the inhibitor's performance over varying durations (ranging from 1 to 48 hours) and concentrations (0.1 to 1 mM). At a concentration of 0.5 mM, the inhibitor demonstrates impressive inhibitory efficiency, ranging from 87.6% at 303 K to 92.9% at 333 K during a 5-hour exposure period. Additionally, the impact of temperature on the corrosion inhibition process is examined at temperatures of 303, 313, 323, and 333 K, showing substantial inhibition efficiencies. Quantum chemical calculations using Density Functional Theory (DFT) methods elucidate the molecular interactions between MPO and the metal surface. Notably, the analysis of EHOMO (Highest Occupied Molecular Orbital Energy), ELUMO (Lowest Unoccupied Molecular Orbital Energy), Egap (Energy Gap), total hardness (η), electronegativity (χ), and electron fraction transition atom (ΔN) reveals valuable insights into MPO's corrosion inhibition capabilities. The outcomes underscore MPO's potential as an effective corrosion inhibitor for mild steel in HCl environments, laying the groundwork for more efficient corrosion prevention strategies in industrial settings.

In this study, we synthesized a novel corrosion inhibitor derived from thiophene and conducted a comprehensive evaluation of its inhibitory properties through both experimental and theoretical approaches. Our investigation encompassed experimental assessments employing Mass loss tests and electrochemical techniques. Additionally, we performed computational studies to delve into the electronic structure and bonding characteristics of the inhibitor, aiming to elucidate its inhibitory mechanism. Our findings revealed that the synthesized inhibitor displayed remarkable inhibitory efficiency, demonstrating its effectiveness in preventing the corrosion of mild steel. Specifically, the thiophene derivative exhibited an impressive inhibitory efficiency of 92.8%, underscoring its potential as a robust corrosion inhibitor for mild steel. Furthermore, this study delved into optimizing the conditions for employing the thiophene derivative as a corrosion inhibitor. Our investigation revealed that the most effective inhibition was achieved at a concentration of 0.5 mM and a temperature of 303 K. To elucidate the interaction between the inhibitor and the mild steel surface, we applied the Langmuir adsorption isotherm concept, shedding light on both the physical and chemical adsorption processes of the thiophene derivative on the metal's surface. Our investigations demonstrated that the addition of the inhibitor significantly reduced the corrosion rate of the metal. Our computational results further reinforced these experimental findings, indicating that the inhibitor formed stable adsorption complexes on the metal surface. This dual confirmation from experimental and computational approaches strengthens the confidence in the inhibitor's efficacy in mitigating corrosion.
