Inhibitive effect of some Schiff bases on corrosion of aluminium in hydrochloric acid solutions

Corrosion Inhibition of Mild Steel in Nitric Acid Media by some Schiff Bases Derived from Anisalidine

“…The protection fi lm on the metal surface consists of mild steel-anisalidine derivatives complex and mild steel oxide. 3. Anisalidine derivatives form a complex on the anodic site of the metal surface through the oxygen atom and nitrogen atom of -OH, -CHO, >C = O, and -NH 2 group.…”

“…Mild steel specimens of the composition of 0.12% C, 0.32% Mn, 0.05% S, 0.02% SiO 2 and the rest of Fe of rectangular specimens dimension 5.0*2.5*0.02 cm 3 containing a small hole of 2 mm diameter near the upper edge were employed for the determination of corrosion rate in a beaker containing 50 ml of test solution at 23 o C with a precision of ±0.5 o C and left exposed to air. While being buffed to produce a mirror fi nish of mild steel, they were cleaned with emery paper then degreased with acetone.…”

“…The inhibition efficiency was also determined using a thermometric technique 21 . These specimens 5.0*2.5*0.02 cm 3 with a precision of ±0.5 o C were left exposed to air. Evaporation losses were made up with deionized water.…”

Synthesis and Characterization of New Transition Metal Complexes of Schiff-base Derived from 2-Aminopyrimidine and 2,4-Dihydroxybenzaldehyde and Its Applications in Corrosion Inhibition

“…15 Some Schiff-bases have been reported as corrosion inhibitors for steel, copper and aluminium. [15][16][17] In this study, we have synthesized new complexes of Schiff-base derived from 2-aminopyrimidine and 2,4-dihydroxybenzaldehyde. These complexes have been charac-2-Aminopyrimidine 및 2,4-Dihydoxybenzaldehyde 치환체인 Schiff-염기의 전이금속 착물에 대한 합성 및 특성 그리고 부식방지에의 응용 403 2010, Vol.…”

3-Formylindole-4-aminobenzoic Acid: A Potential Corrosion Inhibitor for Mild Steel and Copper in Hydrochloric Acid Media

“…The heteroatoms present in these molecules are of key importance and are responsible for the corrosion inhibition in acidic media on the metal surface [1][2][3]. Some recently reported Schiff bases showed effective inhibition for mild steel (MS), aluminum, copper, and zinc in acidic media [4][5][6][7][8][9][10][11].…”
