“…As shown in Table 1 , most of the tested heterocyclic organic compounds have significant inhibitory efficacy. PMBMH has the strongest inhibitory ability of the heterocyclic organic compounds reported in Table 1 [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ], with a performance equivalent to those reported in [ 15 , 23 , 26 , 28 ]. As the concentration of PMBMH increases, the rate of corrosion decreases, and the inhibitive efficacy improves.…”

Using traditional weight-loss tests, as well as different electrochemical techniques (potentiodynamic polarization and electrochemical impedance spectroscopy), we investigated the corrosion-inhibition performance of 2,2′-(1,4-phenylenebis(methanylylidene)) bis(N-(3-methoxyphenyl) hydrazinecarbothioamide) (PMBMH) as an inhibitor for mild steel in a 1 M hydrochloric acid solution. The maximum protection efficacy of 0.0005 M of PMBMH was 95%. Due to the creation of a protective adsorption layer instead of the adsorbed H2O molecules and acidic chloride ions, the existence of the investigated inhibitor reduced the corrosion rate and increased the inhibitory efficacy. The inhibition efficiency increased as the inhibitor concentration increased, but it decreased as the temperature increased. The PMBMH adsorption mode followed the Langmuir adsorption isotherm, with high adsorption-inhibition activity. Furthermore, the value of the indicated that PMBMH contributed to the physical and chemical adsorption onto the mild-steel surface. Moreover, density functional theory (DFT) helped in the calculation of the quantum chemical parameters for finding the correlation between the inhibition activity and the molecular structure. The experimental and theoretical findings in this investigation are in good agreement.

An effective method for designing new heterocyclic compounds of 6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile derivatives (CAPDs) was presented through cyclocondensation reaction between 2,5-diarylidenecyclopentanone derivatives and propanedinitrile, and the cyclocondensation reaction succeeded using a sodium alkoxide solution (sodium ethoxide or sodium methoxide) as the reagent and the catalyst. The synthesized CAPD derivatives were employed as novel inhibitors for carbon steel (CS) corrosion in a molar H 2 SO 4 medium. The corrosion protection proficiency was investigated by electrochemical measurements (open circuit potential vs time ( E OCP vs t ), potentiodynamic polarization plots (PDP), and electrochemical impedance spectroscopy (EIS)) and surface morphology (scanning electron microscopy (SEM)) examinations. The results show that the CAPD derivatives exhibit mixed type inhibitors and a superior inhibition efficiency of 97.7% in the presence of 1.0 mM CAPD-1 . The adsorption of CAPD derivatives on the CS interface follows the Langmuir isotherm model, including physisorption and chemisorption. Scanning electron microscopy (SEM) exploration confirmed the adsorption of the CAPD derivatives on the CS substrate. Monte Carlo (MC) simulations and DFT calculations revealed that the efficacy of the CAPD molecules correlates well with their structures, and this protection was attributed to their adsorption on the CS surface.

“…As a result of the exchange of lone pair electrons between heteroatoms (N and O) and the vacant iron d-orbital, which consequences in a moderate rise in surface absorption potential, it is presumed that adsorption on the surface of the metal will be signi cantly greater. It is because the exchange of lone pair electrons results in a moderate rise in surface absorption potential [53][54][55]. 3) Chemical softness and hardness predict the inhibitor's metal-surface adsorption a nity [40,58,59].…”

“…This exchange of electrons consequently results in the generation of a protective organic layer that coats the surface of the metal and preserves it from corrosion [43,48,[52][53][54]. Electron acceptors, also called LUMOs, are parts of an inhibitor's structure that are responsible to take electrons from a surface with a lot of electron density, like the surface of a metal [47,49,50].…”

Three synthesized Schiff base named 2,2’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)disphenol (I1), 4,4’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2-methoxyphenol) (I2) and 6,6’- (((2,2-dimethylpropane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2-methoxyphenol) (I3) were evaluated as corrosion inhibitors for API 5L grade B steel in the artificial seawater by electrochemical impedance, polarization and Quantum chemical calculations methods. The results showed that all three compounds act as good inhibitors for carbon steel, but the I3 has the best inhibition efficiency of about 58% at 1mg/L. The results of density functional theory method were consistent with the experimental results.
