Alkynyl alcohol derivatives (N‐14) were synthesized by 2‐chloromethyl pyridine, propargyl alcohol and bromotetradecane and the structure was confirmed by 1H NMR, 13C NMR, MS and FTIR. The corrosion inhibition performance was evaluated by weight loss, Tafel polarization, EIS measurements and DFT quantum calculations. The results proved that N‐14 effectively inhibited the acid corrosion of N80 steel. The corrosion inhibition of N‐14 increased with its concentration and decreased with increasing temperature. A maximum of 99.56% inhibition efficiency was achieved using 5 × 10−5 mol/l of N‐14 at 60°C. Thermodynamic parameters showed that the adsorption of N‐14 on N80 steel is spontaneous and exothermic, conforming to Langmuir's adsorption. Electrochemical results showed that N‐14 behaved as a mixed‐type inhibitor. In addition, corrosion products produced on N80 steel surface were researched by SEM, XRD, UV and contact angle. At the same time, the corrosion inhibition mechanism was discussed.

This study takes a detailed look at the corrosion inhibition capabilities of two benzodiazepine‐derived organic compounds, 3,3‐dimethyl‐11‐(4‐nitrophenyl)‐2,3,4,5,10,11‐hexahydro‐1H‐dibenzo[b,e][1,4]diazepin‐1‐one (PNO) and 3,3‐dimethyl‐11‐(2‐nitrophenyl)‐2,3,4,5,10,11‐hexahydro‐1H‐dibenzo[b,e][1,4]diazepin‐1‐one (ONO), in a 1.0‐M hydrochloric acid environment using a variety of analytical methods, including electrochemical approaches — electrochemical impedance spectroscopy (EIS) and potentio‐dynamic polarization (PDP). The results show that the concentration‐dependent inhibitory efficacy of PNO and ONO increases with increasing concentration. Both inhibitors exhibit mixed‐type behaviour, which is confirmed by the polarization results. At the optimum concentration, the inhibition efficiencies of PNO and ONO are 92.9% (PNO) and 87.6% (ONO), respectively. The effective adsorption of these inhibitors on the metal surface was also confirmed by X‐ray photoelectron spectroscopy (XPS) analysis. The existence of a barrier layer surrounding the mild steel was demonstrated using scanning electron microscopy (SEM) and energy‐dispersive X‐ray analysis (EDX), all of which were used to study the surface characterization. The most important interactions with the iron surface are achieved by inhibitors with electron‐accepting properties, according to density functional theory results and molecular dynamic simulation (MDS). With encouraging prospects for industry and metal preservation, these results pave the way for promising applications for effective corrosion protection in a 1.0‐M HCl environment.

Chitosan was used as the raw material. A quaternization reaction was carried out between 2,3-epoxypropyltrimethylammonium chloride and water-soluble chitosan to prepare quaternary ammonium salt water-soluble chitosan (QWSC), and its corrosion inhibition performance against the corrosion of carbon steel in stone processing wastewater was evaluated. The corrosion inhibition efficiencies of QWSC on carbon steel in stone processing wastewater were investigated through weight loss, as well as electrochemical and surface morphology characterization techniques. The results show that QWSC has superior corrosion inhibition performance for A3 carbon steel. When an amount of 60 mL·L−1 is added, the corrosion inhibition efficiency can reach 59.51%. Electrochemical research has shown that a QWSC inhibitor is a mixed-type corrosion inhibitor. The inhibition mechanisms of the QWSC inhibitor revealed that the positive charge on the surface of carbon steel in stone wastewater was conducive to the adsorption of Cl- in the medium, which produced an excessive negative charge on the metal’s surface. At the same time, the quaternary ammonium cation and amino cation formed in QWSC in stone processing wastewater can be physically absorbed on the surface of A3 carbon steel, forming a thin-film inhibitor to prevent metal corrosion.
