“…These groups can increase the electron density of nitrogen through inductive effects [76]. Besides, longer hydrocarbon chains form a hydrophobic layer in the outer part of the inhibitor film for repelling water molecules [79]. The hydrophobic film was also produced from the adsorption of the carboxyl group as lewis base on the metal surface as Lewis acid [80].…”

This comprehensive review highlighted how the expired drugs manage corrosion reactions on metal/alloy surfaces, especially types of carbon/mild steel, Sabic iron, copper, and aluminium in NaCl or acid solution. Several types of expired drugs and the optimum conditions presented in this review were summarized from relevant studies. The performance of expired drugs which covers inhibition efficiency, inhibition mechanisms, and metal surface analysis was informed. The contribution of the chemical composition, molecular structure, compatible treatment conditions, and some corrosion analysis methods were mentioned. Current challenges and future prospects were also discussed for further investigations and developments to obtain superior inhibitors and save the environment.

“…N,O-CMCs has too large molecular size, which can be adsorbed and occupies a wider area on the carbon steel surface. Adsorption processes of polymeric inhibitor on metal surface in aqueous solution are via substitution reactions with water molecules [38]. There are many heteroatoms (oxygen and nitrogen) and π electrons of Electrostatic and/or dipole-ion interactions can also occur among iron ions and/or iron atoms on the metal surface with carboxylate ions from N,O-CMCs compounds (physisorption).…”

The presence of salts and dissolved gas like CO2 that is carried with natural gas and crude oil along the pipeline is the main reason for corrosion and scale formation. These problems are usually resolved separately by corrosion inhibitors and scale inhibitors or acidification. Meanwhile, utilizing a compound to resolve both corrosion and scale formation has an advantage in the economic side and working time. N,O-carboxymethyl chitosan or N,O-CMCs is one of the chitosan's derivates. It is water-soluble and has different functional groups. Those properties support its capability as a complexing agent on corrosion and scale inhibitors. Synthesis of N,O-CMCs was carried out by chemical reactions between chitosan and chloroacetic acid under alkaline circumstances. N,O-CMCs product was characterized using FT-IR and 1H-NMR spectroscopy. The inhibition efficiency was analyzed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The measurements showed that the highest efficiency of corrosion inhibition reached 63.54% when the concentration and temperature were 30 ppm and 35 °C, respectively. N,O-CMCs was classified as a mixed-type inhibitor. The adsorption mechanism of the inhibitor followed Langmuir adsorption isotherm. The static scale inhibition test informed that the optimum inhibition efficiency of N,O-CMCs reached 60.00%.

“…17 Due to the high electron density of amides, adhesion to the metallic surface has been increased, while the long alkyl chain repels against water, resulting in corrosion inhibition. 18,19 Nowadays, researchers mend their work towards synthesizing novel multifunctional additives that incorporate the sludge inhibiting and engine cleanliness characteristics along with excellent viscosity and low-temperature properties. keeping this in view, some efforts were made in the past, for example, the strategy of incorporated nitrogen and oxygen-based compounds were tried.…”

Three polymeric amides were developed by utilizing three acrylates of alkyl chain C‐8, C‐12 and C‐18 and maleic anhydride via polymerization pathway followed by successful coupling with N‐phenyl‐p‐phenylenediamine to give poly(Ac8‐co‐MA)PPA, poly(Ac12‐co‐MA)PPA and poly(Ac18‐co‐MA)PPA. After successful molecular identification, application as lubricant additives as viscosity index improver, pour point depressants, deposit control agents and anticorrosion was done in polyol based synthetic lube oil. A rheological study was also carried out. For comparative performance evaluation, the commercial additives were also taken. Because of the diphenyl moiety in the molecular structure, additives showed the DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) radical scavenging activity. Poly(Ac18‐co‐MA)PPA additive at a high concentration of 5000 ppm, the viscosity index increased from 179 to 217 while the pour point decreased from −18 to −30°C. As far as the detergent dispersant property is concerned, poly(Ac18‐co‐MA) reduced the coking value from 87.5 to 13.2 mg, while % dispersancy increased from 20% to 42%.
