Abstract

The influence of some thiazole derivatives namely, 2-benzylideneamino-4-phenylthiazole (BAPT), 2-cinnamylideneamino-4-phenylthiazole (CAPT), 2-dimethylaminobenzylideneamino-4-phenylthiazole (DAPT), 2-furfurylideneamino-4-phenylthiazole (FAPT) and 2-salicylideneamino-4-phenylthiazole (SAPT) on corrosion inhibition of mild steel in 15% hydrochloric acid solution under boiling conditions has been studied using weight loss method. All the tested thiazole derivatives showed very good inhibition efficiency. Potentiodynamic polarization measurements reveal the fact that all the investigated thiazoles are of mixed type inhibitors and they inhibit corrosion of mild steel by blocking the active sites of the metal surface. The adsorption of these inhibitors on the mild steel surface from 15% HCl has been found to obey Temkin’s adsorption isotherm
