Three new organic inhibitors, namely, dicinnamylidene acetone (DCA), disalicylidene acetone (DSA), and divanillidene acetone (DVA), were synthesized in the laboratory and their inhibiting action was studied on corrosion of N-80 alloy in boiling hydrochloric acid (HCl) by the weight loss method. DSA exhibited the best performance, giving an inhibition efficiency of 98.7%. Potentiodynamic polarization studies revealed that all three organic compounds were mixed-type inhibitors. The adsorption of all three compounds on N-80 alloy followed Temkin’s adsorption isotherm. All three inhibitors exhibited synergistic effects with the addition of potassium iodide (KI). Effect of immersion time was also studied for 24 h.
