“…The synthesis of tailor-made polymeric surfactants has been gained a considerable interest that offers a more significant opportunity in terms of flexibility and functionality [17][18][19]. The application of surfactants as corrosion inhibitors has been studied by some authors [20][21][22][23].…”

T WO new polycationic surfactants abbreviated as (PTEAA.10 and PTEAA.12) were prepared by homopolymerization of triethanolamine acrylate monomer followed by quaternization with 1-bromodecane and 1-bromododecane. FT-IR, 1 H-13 CNMR, and GPC have been used to confirm the chemical structure of the prepared surfactants. The prepared polycationic surfactants have been tested as corrosion inhibitors for carbon steel X65 in formation water. Weight loss, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization accompanied by SEM and EDX techniques were used to study the inhibition performance of PTEAA.10 and PTEAA.12. The prepared polymeric cationic surfactants act as mixed type inhibitors according to Tafel data. The inhibition efficiency of PTEAA.12 at 250 ppm was 92.8 %. The inhibition action was attributed to the formation of the adsorbed layer of surfactants over X65 surface that was follow Langmuir adsorption isotherm. The resistance of the adsorbed layer () was a function in concentration and hydrophobicity of the surfactants.

“…Recently, many surfactant compounds have shown an impressive inhibition efficiency as a corrosion inhibitor for protecting C-steel from corrosion in petroleum sector (Al-Sabagh et al , 1996). The main benefits of utilizing the surfactant materials in steel protection are their impressive inhibition efficiency, low toxicity and the easy routes for preparing the surfactant materials (Abd-El-Naby et al ., 2016).…”

Purpose The purpose of this study is to inspect the corrosion inhibition of API N80 steel pipelines in uninhibited solution and inhibited with a synthesized surfactant compound [N-(3-(dimethyl octyl ammonio) propyl) palmitamide bromide] (DMDPP), which is prepared through a simple and applicable method. Design/methodology/approach Weight loss was inspected at five different temperatures of 25°C, 30°C, 40°C, 50°C and 60°C Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation were used at room temperature. Density functional theory was used to study the relation between the molecular structure and inhibition theoretically. Findings Adsorption of the prepared DMDPP fits the Langmuir isotherm model. The inhibition efficiency of the prepared DMDPP amphipathic inhibitor is directly proportional to temperature increase. Polarization results reveal that the investigated DMDPP amphipathic compound behaves as a mixed-type inhibitor. EIS spectra produced one individual capacitive loop. Originality/value The originality is the preparation of cationic surfactants through a simple method, which can be used as corrosion inhibitors in oil production. The synthesized inhibitors were prepared from low-price materials. The work studied the behavior of the synthesized surfactants in inhibiting the corrosion of the steel in an acidic medium. Electrochemical and theoretical studies were presented, besides gravimetric and surface examination.

“…Other acids form metal salts such as nitrates, phosphates and sulfates which are have very low solubility in water 3 . Lately, most of prepared surfactants are utilized as corrosion hindrance for C-steel in industry domain 4 . Surfactants are very good corrosion inhibitors due to their high inhibiting productivity, little toxicity, little price and easy production 5 .…”

This study aimed to examine the corrosion inhibition of C-steel in 1.0 M HCl solution by synthesized surfactants. Mass loss (ML) investigated at five different temperatures 25-45 o C, while electrochemical impedance spectroscopy (EIS), Tafel polarization (PP) and electrochemical frequency modulation (EFM) were tested at 25°C. The results showed that the synthesized surfactants were good one and its protection efficiency (%η) was improved by raising both the dose and temperature. PP diagrams confirmed that the prepared surfactants are mixed inhibitors. The decrease in the capacitance double layer and the rise in the resistance charge transfer occur as a result of adsorption of surfactant molecules on C-steel. The adsorption of these inhibitors fit Langmuir model. The thermodynamic parameters were measured and explained. Scanning electron microscope (SEM), the energy dispersive X-ray spectroscopy (EDX), and atomic force microscopy (AFM) were utilized to study the surface morphology of C-steel which revealed that the inhibitors produce thin film adsorbed in the surface of C-steel.
