| Summary: | In this paper, synthesized organic compound of the family of ketene dithioacetal was studied as corrosion inhibitors for mild steel in 1.0 M hydrochloric acid by gravimetric measurement. The aim of this work is to study the effect of inhibitor concentration and the temperature on the resistance, corrosion and to compare the experimental results with mathematical models. The structural properties were performed using scanning electron microscopy technique. It has been found that the inhibition efficiency, increases with increasing inhibitor concentration. The adsorption of studied compounds on mild steel surface follows Langmuir’s isotherm. Obtained data were analyzed by suggesting two mathematical models based on linear and quadratic regression, taking into account the influence of concentration and temperature on the inhibition efficiency. Obtained experimental data were in good agreement with those predicated by the quadratic model
