Summary:Newly synthesized 3-(3-bromophenyl)-2-imino-2,3-dihydrobenzo[d]oxazol-5-yl 4-methylbenzenesulfonate (3-BrPhOXTs) inhibitory effect on the corrosion of stainless steel L316 (SS) in sulfuric acid was investigated by means of potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). According to electrochemical results, excellent inhibiting properties for SS corrosion in sulfuric acid has been obtained. The adsorption of 3-BrPhOXTs onto the SS surface followed the Langmuir adsorption model with the free energy of adsorption ?G 0 ads of -8.94 kj mol -1 .
