“…(7) yields a straight line with all linear correlation coefficients (R 2 ) is nearly equal to 1 and the slope values are also close to 1. Thus, the Langmuir model was found to give the best description (Figs.8 9) 6 . It follows from the data presented in Table 6 that the adsorptive equilibrium constant (K) increased with increasing temperature.…”

“…In Table 9, it can be noted that the adsorption energy of the inhibitors is negative in each case. This means that the adsorption on the surfaces of both inhibitors is spontaneous and that the interaction between them will take place in aqueous and gas phases 49,6 . The adsorption energies of the molecules studied improved in the order of HMP < PMP and this latter molecule gave the highest adverse energy of adsorption.…”

“…Therefore, it is possible to suggest that the presence of heteroatoms facilitates the adsorption of their molecules onto the surface, thereby reducing the corrosion rate in acidic solutions. The inhibition properties in the acidic medium of these compounds can be attributed to the number of mobile electrons pair present, the π orbital character of free electrons and the electron density around nitrogen and oxygen atoms [4][5][6] . Due to the inimical effect of some chemicals, research activities in recent times are towards developing cheap, nontoxic and environmentally safe corrosion inhibitors low-cost [7][8][9] .…”

The aim of the present work is to evaluate the protective ability of newly menthone derivatives 7-isopropyl-4-methyl-4,5,6,7-tetrahydro-1H-indazole (HMP) and 7-isopropyl-4-methyl-1-phenyl-4,5,6,7-tetrahydro-1H-indazole (PMP) as mild steel corrosion inhibitors in 1M HCl, which may get applications as eco-friendly corrosion inhibitors in acidizing processes in the industry. The corrosion attitude of mild steel at various concentrations of the inhibitors was examined in the range from 298 to 328 K. An increase in the inhibitory effectiveness in acidic solution at higher concentration and temperature follow the existence of inhibitors. The aspect of adsorption mixed type of inhibitors was highlighted by the Polarization curves. The adsorption of HMP and PMP is in line with the Langmuir isotherm model. Theoretical indices study of both inhibitors (HMP and PMP) via CDFT (the conceptual density functional theory) has been studied. To search for the best spatial configuration of steel/inhibitor a Monte Carlo simulation studies were applied.

Corrosion is a phenomenon that devastatingly affects innovative, industrial, and mechanical applications, especially in the oil and gas industries. The corrosion conceivably influences industrial equipment; it deteriorates the environment and lessens the equipment/infrastructure's lifetime. Considering the significant impact of corrosion in our daily lives, this review article aims to briefly discuss the significance of corrosion and different control methods with special attention on corrosion inhibitors. The classification of corrosion inhibitors based on types and their advantage/ limitations, and heterocyclic compounds as potential corrosion inhibitors, mainly nitrogen-based compounds (pyridine (1N), pyrimidine (2N), and triazines (3N) fused ring benzimidazole, etc.), and their biological significance has been discussed in detail. The mechanism, challenges, and applications of heterocyclic compounds as corrosion inhibitors in various industrial relevant corrosive environments such as acid pickling, descaling operation in the desalination plant, oil gas industry, etc., have also been highlighted in the review.
