Abstract

Green synthesis has become very significant for sustainable development and health concern. The multicomponent is applied as an eco-friendly procedure to synthesize N-((2-aminoethyl) carbamothioyl) acrylamide (ACA). The structure of ACA is verified using FTIR and ¹HNMR spectroscopy. The inhibitory effect of ACA for carbon steel in 1 M HCl is assessed using electrochemical measurements and weight loss. The Langmuir adsorption isotherm model fits the inhibitive effect caused by adsorption on the metal surface. Additionally, the surface morphology is examined using SEM and AFM. The photos demonstrate a smoothing of the protective surface and a 0.45 nm reduction in average roughness. Different quantum descriptors using DFT theory were calculated and found to be corroborated with the experimental results. By creating successive resistive adsorption films, the ACA, at a concentration of 10⁻³ M, protects the carbon steel in 1MHCl with a 97% efficiency as a mixed-type inhibitor.

N-((2-氨基乙基)氨基硫酰基)丙烯酰胺对碳钢在1m HCl中的缓蚀特性、热力学及理论研究

绿色合成对可持续发展和健康问题具有重要意义。采用多组分法合成N-((2-氨基乙基)氨基硫酰基)丙烯酰胺(ACA)。用FTIR和1HNMR对ACA的结构进行了验证。采用电化学测定和失重法评价了ACA对碳钢在1 M HCl中的抑制作用。Langmuir吸附等温线模型拟合了金属表面吸附产生的抑制效应。此外，使用扫描电镜和原子力显微镜检查表面形貌。照片显示保护表面平滑，平均粗糙度降低了0.45 nm。利用DFT理论计算了不同的量子描述子，并发现与实验结果相吻合。通过形成连续的电阻吸附膜，ACA在10−3 M的浓度下，作为混合型抑制剂，在1MHCl中以97%的效率保护碳钢。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
