In this paper, vegetable oil-derived amide corrosion inhibitor (SDLTF) was synthesized using soybean oil, diethylenetriamine and formaldehyde as raw materials. The effect of temperature and the amount of corrosion inhibitor on the corrosion inhibition effect was investigated by weightlessness test, and the inhibition performance, adsorption behavior and mechanism of SDLTF on A13 steel in 5% hydrochloric acid were studied by adsorption model and thermodynamic parameters. The results show that when the amount of corrosion inhibitor is 50mg / L, the corrosion inhibition efficiency is the highest, which can reach 91.20%. By simulating the isothermal curve, it was found that SDLTF conforms to the law of Langmuir isotherm adsorption.
