Synthèse et étude du pouvoir compexant et inhibiteur d’une base de schiff

Abstract

This Work is dedicated in the first time to the synthesis of a newly tétradentates ligand Schiff bases by the actions of aromatic diamine (4,4’-diaminodiphénylméthane) with Thiophene-3, carboxaldehyde. For give Ligand (SN), and its mono and binuclear complexes of Cu (II), Ni (II)and Co (II). On the second step, theseproducts were characterised using spectroscopic determinationsas the infrared (IR),ultraviolet(UV-vis), nuclear magnetic resonance (NMR lH) and the analysisdifferential scanning calorimetry (DSC). Anelectrochemical study by cyclic voltammetry of ourLigand and its complexes has been achieved in middle organic DMF-TBAP O.1M on the bothelectrode of vitreous carbon has the diameter (2 mm). On the third time, investigation this synthesizedSchiff base (SN) as corrosion inhibitor for steel X52 in acid media.The results obtained seem ratherencouragement what will cause to take an action pursuant of this work later on.
