Abstract

Mass loss and thermometric methods are used to study the inhibition of corrosion of mild steel in hydrochloric acid by Schiff’s bases N-(furfurlidine)-4-methoxy aniline, N-(furfurlidine)-4-methylaniline, N-(salicylidine)-4-methoxy aniline, N-(cinnamalidine)-4-methoxy aniline, and N-(cinnamalidine)-2-methylaniline. Results of inhibition efficiency yielded by the two methods are in good agreement and depend on the inhibitor and acid concentration. Maximum inhibition efficiency is 98%. The efficiency increases with the inhibitor concentration and acid strength.
