Abstract New Corrosion inhibitor named 2,5-bis（2-hendecyl）-1,3,4-oxadiazole（HOX） was synthesized and characterized.Its inhibiting behavior for carbon steel in 1mol/L and 2 mol/L hydrochloric acid was in-vestigated by means of weight loss, potentiodynamic polarization curves and electrochemical impedance meth-ods. The results show that it behaves excellent as inhibitor at very low concentration. HOX suppressed both cathodic and anodic processes of steel corrosion in 1 mol/L and 2 mol/L HCl solution by chemisorption on steel surface. It also indicates the adsorption is according to a Langmuir isotherm adsorption model.
