Novel Quaternary Ammonium-Based Cationic Surfactants: Synthesis, Surface Activity and Evaluation as Corrosion Inhibitors for C1018 Carbon Steel in Acidic Chloride Solution
A novel class of quaternary ammonium-based cationic surfactants is synthesized and characterized via spectroscopic methods (FTIR, 1 HNMR and13 C NMR). The surface properties, foaming power and biodegrad-ability of the synthesized cationic surfactants are deter-mined using the surface tension technique. The protection performance with their adsorption mecha-nisms for carbon steel is evaluated in a 15% HCl solu-tion by a series ... Read more

Corrosion inhibition of carbon steel pipelines by some novel Schiff base compounds during acidizing treatment of oil wells studied by electrochemical and quantum chemical methods
Three novel Schiff bases compounds were prepared and their structures were characterized by X-ray, 13C-NMR, 1H-NMR, mass, UV–Vis, FT-IR, spectral data and elemental analyses. The corrosion inhibition of the investigated inhibitors towards carbon steel in 15% HCl was investigated by using electrochemical measurements (EIS, LPR corrosion rate and Tafel plots), SEM, EDX and quantum chemical methods. The results showed that, ... Read more
