Abstract

In the current study, two quinazoline derivatives di-cationic surfactants, that contain long carbon chain, have been synthesized. Their structures were supported by spectroscopic methods, and their anticorrosive protection on mild steel was tested in acidic medium at room temperature for 24 h. Corrosion processes were evaluated by the gravimetric method based on the weight loss of metal plates. Fairly good corrosion inhibition efficiencies (92.44%-95.49%) were achieved at different concentrations of the inhibitors. SEM images of the metal surfaces supported the corrosion inhibition efficiency of the products.
