| Abstract: | 2-(Allylthio)-1H-benzoimidazole(ABMI) and 2-(butylthio)-1H-benzoimidazole(BBMI) have been synthesized.Their corrosion inhibition has been investigated towards the corrosion of Q235 steel in 1M HCl solution by weight loss and potentiodynamic polarization techniques.The results show that the inhibition efficiencies of ABMI and BBMI were up to 95.20% and 87.32% by the inhibitor concentration of 100 mg/L in 1 M HCl solution at 25℃,respectively.ABMI was a mixed-type inhibitor,but BBMI was a mixed-type inhibitor which mainly inhibits anodic reaction.Their corrosion rate decreased with increasing temperature,but the corrosion inhibition of ABMI was better than BBMI at same temperature.The adsorption of the two compounds obeyed the Langmuir's adsorption isotherm and belonged to spontaneous chemisorptions. |
