Based on rapeseed oil and soybean oil, and diethylenetriamine and formaldehyde, a plant oil derived amide inhibitor was synthesized. The inhibition performance of plant oil derived amide inhibitor on A13 steel in 1 mol / L hydrochloric acid was studied by weight-loss experiment, electrochemical analysis and quantum chemical calculation. The adsorption behavior and mechanism of the inhibitor on A13 steel surface were revealed. The results of electrochemical experiments were consistent with the results of weight loss tests. The contact angle test results showed that the plant oil derived amide inhibitor can significantly enhance the hydrophobicity of A13 steel surface. The thermodynamic parameters show that the adsorption of plant oil derived amide inhibitor on A13 steel surface was self. The results of quantum chemical calculation showed that there are a lot of active sites in the structure of amide inhibitor derived from vegetable oil.
