الوصف: Alanine hydrochloride was prepared from alanine, then its derivative was synthesized by amidation. The structure of the synthesized product was characterized by infrared and 1H nuclear magnetic resonance. The corrosion inhibition effect of alanine and alanine derivative on carbon steel at 30 ℃ in 0.5 mol/L sulfuric acid medium was studied by weight loss method, electrochemical method and scanning electron microscope. The results showed that alanine derivative had better corrosion inhibition than alanine due to the hydrophobic alkane long chain. The weight loss method and electrochemistry showed that the corrosion inhibition rate reached more than 90% at the alanine derivative dosage of 300 mg/L. The adsorption of corrosion inhibitor on carbon steel surface conformed to Langmuir adsorption model. Alanine derivative at low mass concentrations(50-100 mg/L) could inhibit the oxidation of anode metal,which was anode corrosion inhibitor. At higher mass concentrations(200-500 mg/L), the rate of hydrogen evolution reaction at the cathode and metal oxidation reaction at the anode was reduced at the same time, thus reducing the overall corrosion reaction rate, so alanine derivative was a mixed corrosion inhibitor.
