“…Inhibitors, whether synthetic or of green origin, mostly act by adsorptive interaction with the surface to be protected [40]. Such interaction is supported by functional groups in particular with heteroatoms (amino groups, sulfur-containing groups) and by structural specifics like double or triple bonds or aromatic ring systems [41][42][43] or pronounced polarity of a potential inhibitor molecule [44]. Such adsorption can be verified in many cases by spectroscopic methods [45].…”

The substituted aromatic amine o-toluidine (2-methylaniline, 1-amino-2-methylbenzene) is frequently encountered in electrochemical research as a soluble corrosion inhibitor dissolved in aqueous media used e.g., in cooling systems, as a homomonomer for formation of intrinsically conducting poly-o-toluidine and as a comonomer in formation of respective copolymers and their composites. The obtained polymers are suggested as corrosion protection coatings, as active materials in devices for electrochemical energy storage, but more frequently, they are examined as active components in electrochemical sensors.The significant and pronounced carcinogenicity of o-toluidine has hardly been addressed; presumably, most researchers are not even aware of this property. After a brief summary of the health risks and effects, the following overview presents typical examples of said studies and applications. If possible, substitutes with lower health risks are proposed, at least further studies enabling such replacement are suggested.

“…The phenomenon of adsorption forms the basis of the corrosion inhibition in which inhibitor gets accumulated onto the metal surface, thus, shielding the surface from encountering corrosion or by retarding electrochemical processes [33]. The corrosion inhibitors can be chosen on the basis on 1) structural features, and 2) theoretical considerations.…”

Corrosion is emerging as a potential hazard which abolishes metals and their structures and hence become an imperative menace. It is an omnipotent and omnipresent process which is present in every environment, i.e., air, soil, water. Green chemistry is one of the notable branches of chemistry that focuses on the protection of environment and human well–being in an economically viable approach allowing dodging of toxins and reducing hazards due to corrosion. Green chemistry exploited well–known strategy namely green inhibitors to prevent, control or impede the growth of corrosion. Green inhibitors are eco–friendly, cost–effective, renewable natural products which are favourable over toxic synthetic corrosion inhibitors. Extracts of natural products contain natural products containing alkaloids, carboxylic acids, nicotine, polyphenols, quinine, terpenes, and other functional groups possessing elements like C, N, O, S, etc., prompting adsorption via forming a thin layer (coating) on the metallic surface to shield the surface and encumber corrosion. In the field of economical loop, this approach develops various potential applications in manufacturing areas other than ‘Trash to treasure’. Even though a bunch of experiments have been performed and several research articles have been in print, however, the area of green inhibitors is still demanding more investigation on this open issue. More and more interest in the area extended the research, consequentially to a large variety of tried molecules. Nevertheless, the most accepted protocols are classical and, therefore, are incompetent to completely portray the probable worth of inhibitors. Hence all above stated features should be the objective of the contemporary research so that productive analysis to emphasize the weak areas of the green inhibitors field and tackle the prospect research in the field that still requires validation.
