A new N- and S-containing heterocyclic compound, CAHMT, was synthesized and evaluated as a corrosion inhibitor for oil-well tubular steel (N-80) and mild steel (MS) at 105°C ± 2°C by the weight loss method. Potentiodynamic polarization measurements were carried out at room temperature for both steels in the presence of propargyl alcohol (PA) and CAHMT. Results indicate that the CAHMT is a mixed-type inhibitor while PA is predominantly cathodic. The adsorption of the inhibitors on N-80 steel and MS surface from 15% hydrochloric acid (HCl) has been found to obey Temkin’s adsorption isotherm. The efficiency of CAHMT has been found to be comparable with that of PA, a standard corrosion inhibitor for MS in boiling HCl.
