“…Since these orbitals allow the backward supply of electrons from metal dorbitals, the inhibitor-metal bond is stabilized. Schiff bases and their metal complexes have important uses in medicine as antibacterial, antioxidant, and anti-in ammatory agents, as well as in industry as corrosion inhibitors [21][22][23].…”

Weight loss (WL), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PP) are utilized to investigate the effectiveness of prepared Schiff base N,N′-bis(salicylidene)-butylene-1,4-diamine (SB) as an inhibitor for the dissolution of carbon steel (CS) in 0.5 mol L-1 HCl. The SB structure is confirmed by 1HNMR and FTIR. The mitigation efficacy increased with raising the SB concentrations. The maximum efficacy is 84% at 300 ppm of the investigated inhibitor. However, at 300 ppm, the efficacy reduced from 84 to 80.7% when the temperature elevated from 298 to 333 K. The tested inhibitor reduced the corrosion current density (Icorr) and double-layer capacitance (Cdl) because of the growth of a protective film on the CS surface. The inhibitor matches the Langmuir adsorption isotherm and exhibits mixed-type inhibitor behaviour. The formation and adsorption of a consistent layer at CS in the availability of the SB compound were detected by SEM and EDX investigation. Density functional theory (DFT) and Monte Carlo (MC) simulations were employed to explain the nature of the interaction between the SB molecules and the CS. The SB compound's effectiveness as an inhibitor was supported by its quantum properties.

“…Schiff bases show biological activities like nematicidal [20], insecticidal [21], antibacterial [22], antifungal [23], antileukaemia [24], anti-inflammatory [25], anti-HIV activity [26], antimycobacterial activity [27], antioxidant [28], anticancer [29], and plant growth regulatory activity [30] among others. Besides biological applications, Schiff base and their metal complexes have enormous applications in analytical chemistry [31], dye industry [32], and corrosion inhibitors [33]. Schiff base has attracted the attention of many experimental and theoretical researchers due to their particular photo-luminescence [34] in the visible range and at room temperature and so applied in many realms such as microelectronics [35], optoelectronics [36] and biological sensors [37].…”

Schiff Base in Organic, Inorganic and Physical Chemistry

The development of Schiff base was a major step forward in the area of coordination chemistry. Schiff bases, a class of organic compounds, carry the imine or azomethine (>C=N–) functional group. Schiff bases played an influencing role in the development of coordination chemistry and were a key point in the development of inorganic, bioinorganic chemistry and optical materials. Schiff bases, widely used in inorganic, organic, and analytical chemistry, account for a significant portion of the more commonly employed classes of organic molecules. The ability of Schiff base ligands to form stable metal complexes with a wide range of transition and other metal ions makes them extremely useful. Condensation of a primary amine with an aldehyde or ketone yields a Schiff bases. In this chapter, we focused on introducing Schiff bases, classified them and their metal complexes, and discussed several synthesis methods, including conventional and green approaches. This chapter also elaborated on the industries’ applications, such as the food industry, agrochemical industry, dye industry, analytical chemistry, catalysis, energy storage, environmental, chemo-sensing, bio-sensing, and biomedical applications of novel Schiff bases and their metal complexes.

“…This is required to forecast the process by which corrosion inhibitor molecules will bind to the metal surface. Typically, computational methods based on density functional theory (DFT) are used to calculate these parameters. , In this study, the hydroxyphenyl and benzonitrile-containing diazene, which was held together by an aliphatic chain, was used to synthesize the two Schiff bases S1 and S2. We assessed the corrosion inhibitory potential of S1 and S2 using electrochemical and weight loss experiments.…”

The current study examines the evaluation of diazene-based Schiff base derivatives, namely, 4-((E)-(3-((E)-(hexylimino)methyl)-4-hydroxyphenyl)diazenyl)benzonitrile (S1) and 4-((E)-(3-((E)-(dodecylimino) methyl)-4-hydroxyphenyl)diazenyl)benzonitrile (S2). The structure elucidation of prepared the Schiff base compounds was performed by FTIR, 1 H NMR, and 13C NMR. In addition, the corrosion inhibition capacity of these compounds was investigated for API X65 steel pipelines in 1 M HCl utilizing gravimetric and electrochemical methods. By conducting the experimental investigations at various doses, it was possible to assess the inhibition effectiveness and adsorption behavior of S1 and S2. With increasing concentration, both inhibitors became more effective at inhibiting corrosion. S1 and S2 suppressed both cathodic and anodic processes, as shown by the potentiodynamic polarization study. The charge transfer resistance (R ct ) increased when S1 and S2 concentrations increased, according to the electrochemical impedance analysis (EIS) data. According to the Langmuir isotherm model, the adsorption of S1 and S2 inhibitors on carbon steel was discovered based on gravimetric measurements. The results were confirmed by theoretical data in addition to the experimental tests for the presence of S1 and S2 inhibitor films over the API X65 carbon steel surface.
