In the past, lives and wealth have been lost due to corrosion in almost all engineering fields. Not only this, the cost of reviving damaged equipments in the industry due to corrosion contributed a lot to the gross domestic product of a nation. Thus, all hands must be on desk to combat this harzadous act via time to time research on its final resolution. However, current research works have revealed effective and reliable corrosion inhibitors from pharmaceutical drugs, plant extracts and ionic liquids as organic green corrosion inhibitors (OGCIs) with accommodative attributes such as being environmentally friendly, readily available, biodegradable, non-harmful, relatively cheap and many others to mention a few. This paper opens readers mind into the detailed classifications, mechanisms and active functional groups of these eco-friendly OGCIs. Not only the corrosion efficiency calculation ways but also influencing factors on efficiency were presented. Plant extracts, pharmaceutical drugs, ionic liquids and synthetic inhibitors, as among major sources of OGCIs, used in preventing material corrosion in corrosive media were separately and comprehensively examined. The significance of values obtained from simulating presented mathematical models governing OGCIs kinetics, adsorption isotherm and adsorption thermodynamics was also included. In conclusion, beneficial recommendations for both current and prospective researchers in the field of Corrosion Engineering were presented.

“…[4,5]. Gemini surfactants have a wide range of applications due to their unique properties, including enhanced oil recovery [6], transfection of genes [7], RNAdelivery [8] Inhibition of iron corrosion [9,10], and environmental protection [11][12][13]. Environmental friendly products to replace traditional surfactants can become a major trend as a result of rising governmental pressure and environmental protection.…”

Gemini cationic surfactant is a promising generation of surfactants characterized by their unique surface properties and biological activities. Herein, a series of three Gemini cationic surfactants containing ester bond with different alkyl chain length and their corresponding monomeric structures have been synthesized. The monomeric surfactant were synthesized via simple esterification of different fatty acids (stearic, myrisitic, lauric acid) with 2-dimethyl amino ethanol, followed by quaternization with 1-bromohexane; while, and 1,6-dibromohexane was used to prepare the corresponding Gemini cationic surfactants. The structures of the synthesized compounds were elucidated using 1 H-NMR, FTIR spectroscopy. The biological activities and surface properties have been assayed and it was found that the prepared Gemini surfactants have higher antimicrobial efficiencies than the corresponding monomeric structure.

The efficiency of three new synthesized Gemini surfactants (namely, A312, A314, and A316) of the type 4,4-[1,4phenylenebis(azanylylidene)bis(N,N-dimethyl-N-alkylaminium] bromide is evaluated as corrosion inhibitors for carbon steel API 5L X52 grade in 1M HCl. The relation between the experimental inhibition efficiency and theoretical chemical parameters obtained by computational calculation in order to predict the behavior of the organic compounds as corrosion inhibitors was instigated. The chemical structures were elucidated using 1HNMR spectra. Inhibition performance was investigated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and weight loss tests. The polarization curves show that applied surfactants act as mixed type inhibitors. Nyquist plots showed the semicircle capacitive loop with different surfactants and concentrations. The inhibition efficiency orders are A312 > A314 > A316 with the highest efficiency of 94.87% for A312. Adsorption of inhibitors on API X52 steel surface was found to obey Langmuir isotherm. Theoretical evaluation of the inhibitory effect was performed by computational quantum chemical calculations. The molecule structural parameters (EHOMO), (ELUMO), energy gap (ΔE), and the dipole moment (μ) were determined. The results of experimental inhibition efficiency and theoretical calculated quantum parameters were subjected to correlation analysis.
