摘要：This study aims to find an efficient corrosion inhibitor as a potential alternative to conventional ones used in strong acid environments. BuTT and BeTT were synthesized using a one-step procedure according to the threecomponent condensation. The anticorrosion performance of BuTT and BeTT in 1.0 mol center dot L- 1 HCl were examined via gravimetric measurement, electrochemical analysis and computational chemistry. Results reveal that the corrosion inhibition efficiencies of both BuTT and BeTT nearly exceed 90 % at 298.15 K within the concentration range of 0.05 to 1.0 mmol center dot L- 1, with the maximum inhibition efficiencies of 94.0 % (BuTT) and 94.9 % (BeTT) at a concentration of 1.0 mmol center dot L- 1, respectively. Furthermore, the maximum inhibition efficiencies obtained from BuTT and BeTT also surpass 90 % at a given concentration of 1.0 mmol center dot L- 1 over the temperature range from 288.15 to 318.15 K. Additionally, the adsorption of BuTT and BeTT on the carbon steel surface follow the Langmuir isotherm model. Taken together, gravimetric measurement, electrochemical test and theoretical calculation, indicate that both BuTT and BeTT exhibit excellent inhibition in strongly acidic media.
