英文摘要	Corrosion of copper in 3.5% NaCl solutions and its inhibition by MTYDBH have been studied using weight loss test and various electrochemical techniques. Weight loss measurement gave an inhibition efficiency of about 99.07% with 100mg/L MTYDBH present. Potentiodynamic polarzation measurements showed that the present of MTYDBH in 3.5% NaCl solutions decrease corrosion currents and slightly shifts the corrosion potional in a positive direction. EIS measyrements were used to investigate the mechanism of corrosion inhibition. The corrosion resistance of copper with inhibitors under alkaline conditions is better than that under near neutral or conditions acidic and the order is alkaline > neutral > acidic. The electronic properties such as the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energy levels, and molecular orbital densities were computed.
