Corrosion inhibition of three new synthesized cationic surfactants, N-(2-(((Z)-4-(pyridin-4-yl)but-3-en-bromide IV(4N) on carbon steel was investigated by weight loss, electrochemical impedance spectroscopy and polarization measurements. Results show that the synthesized cationic surfactants inhibit corrosion of carbon steel in 1 M HCl. The inhibitive action occurs by virtue of adsorption on the metal surface following a Langmuir adsorption isotherm model. Polarization curves reveal that the investigated cationic surfactants can be classified as mixed inhibitor types. The variations in the corrosion inhibition efficiency between three cationic surfactants are correlated with their chemical structures, with more hydrophobic surfactants yielding higher inhibition efficiency.

“…In the spectrum of Gemini surfactant, broad bands at 1,688, 1,558, and 1,462 cm −1 are assigned to stretching vibration of C=O, bending vibration of N‐H and characteristic absorption of the quaternary ammonium salt. The peaks at 1,469 and 721 cm −1 were attributed to rocking vibration and bending vibration in the plane of ‐CH 2 , respectively . The characteristic peaks of Gemini C 4 ‐MMT have exhibited a blue shift to some extent, which resulted from the lower content of ‐CH 2 ‐ in C 4 ‐MMT compared with Gemini C 10 ‐MMT and Gemini C 18 ‐MMT.…”

A facile method was proposed to control the morphology and enhance the ultimate mechanical properties of polyethylene/polystyrene (PE/PS) by incorporating Gemini‐surfactant‐ organically modified montmorillonite (OMMT). OMMT was synthesized and incorporated into the immiscible PE/PS to fabricate composites. The effect of OMMT modified with a surfactant of different carbon chain length on the morphology and the final properties of the immiscible PE/PS polymer composites were investigated. FTIR and X‐ray diffraction characterizations revealed OMMT was successfully synthesized. Scanning electron microscopy observation revealed the morphologies of the PE/PS (70/30, w/w)/OMMT composites gradually transformed from “sea‐island” into the co‐continuous structure with the increase of the OMMT loading. The elongation at break of the PE/PS compatibilized with 1.5 wt% of Gemini C10‐MMT can reach as high as 700%. When compared with the PE/PS without OMMT, the flexural strength and modulus of the PE/PS/OMMT composites also have a remarkable enhancement with OMMT content. The flexural modulus of the PE/PS/OMMT composites with 1.5 wt% Gemini C10‐MMT was increased by 22%. POLYM. COMPOS., 40:3254–3263, 2019. © 2018 Society of Plastics Engineers

“…It is seen that incorporating of the inhibitor into the corrosive solution causes a marked decrease in the rate of corrosion, i.e., shifts the cathodic curves toward more negative potentials and the anodic curves toward more positive potentials. This may be due to adsorption of the surfactant molecule on the metal substrate [30]. The important related Tafel indices including anodic and cathodic Tafel slopes (b a , b c ), corrosion potential (E corr ) and the corrosion current density (I corr ) were determined from the polarization plot and are tabulated in Table 1.…”

“…We compared our results with the literature data. Hegazy et al [30] studied the inhibition behavior of novel cationic surfactant, namely N,N 0 -[(oxalylbis(oxy))bis(ethane-2,1-diyl)]bis(N,N-dimethyldodecan-1aminium bromide), for carbon steel tubes corrosion in 1.0 M HCl. They found that in the presence of 5 mM of inhibitor, the inhibition efficiency was 89.02%.…”

A novel class of quaternary ammonium-based cationic surfactants is synthesized and characterized via spectroscopic methods (FTIR, 1 H NMR and 13 C NMR). The surface properties, foaming power and biodegradability of the synthesized cationic surfactants are determined using the surface tension technique. The protection performance with their adsorption mechanisms for carbon steel is evaluated in a 15% HCl solution by a series of techniques including electrochemical impedance spectroscopy, potentiodynamic polarization curves, scanning electron microscopy (SEM), X-ray spectroscopy, and UV-visible spectroscopy. The surfactants are found to be excellent corrosion inhibitors for carbon steel. The results show that the inhibition efficiencies are increased by increasing the concentration and the hydrophobic chain length of the tested compounds reaching the maximum at 250 ppm. The potentiodynamic polarization curves suggested that the inhibitors behave as a mixed type with predominant cathodic inhibition and the corrosion behavior can be explained by the adsorption film mechanism. Moreover, the mode of adsorption obeys the Langmuir adsorption isotherm; also, the adsorbed layer on the surface of the metal is approved by using SEM. . As a researcher, he is currently interested in synthesis of organic compounds and their applications. J Surfact Deterg (2017) 20:735-753 753
