Résumé : |
Ester–quat surfactant: 1,3-bis-[(dodecanoyl oxypropyl dimethylammonium) propane] dibromide referred as 12-3-3-3-12 was synthesized, purified and characterized by Elemental Analysis, 1H-NMR, 13C-NMR, IR and Mass Spectra. The thermodynamic properties of aqueous solutions of this ester-quat were investigated using Electrical Conductivity and SurfaceTension measurements. The corresponding parameters of micellisation were determined for each technique. Otherwise the inhibitive action of the ester-quat (12-3-3-3-12) on the corrosion behaviour of iron was investigated in HCl and H2SO4 medium by means Electrochemical Resistance and Polarisation methods. The ester-quat 12-3-3-3-12 acts as a cathodic-type inhibitor. The maximum inhibition efficiency was reached around the critical micellar concentration. The ester-quat appears to be adsorbed in the metal/liquid interface through the general mode following the Frumkin adsorption model. |
