摘要：

1-[(5-Phenyl-1,3, 4-oxadiazol-2-yl)thio] acetone (POTA) was synthesized and tested as a new corrosion inhibitor for low carbon steel in 1 M hydrochloric acid. The diagnosis of POTA was carried out by FTIR and NMR analysis. Inhibitor performance was investigated using mass loss technique. POTA was acted as a moderate corrosion inhibitor for low carbon steel in 1 M hydrochloric acidic solution with efficiency more than 70%. The inhibitor performance was attributed to the formation of an adsorption layer on the low carbon steel surface. The mechanism of inhibitor adsorption on the low carbon steel surface was according to the Langmuir adsorption isotherm. The value of adsorption heat was within the range of chemical adsorption. Quantum chemical studies were adopted as a theoretical tool to clarify the mechanism of inhibition and to support the experimental part.
