The dendritic tetrameric quaternary ammonium surfactants of tetrachloride•tetra [(2-hydroxyl-3-dodecyldimethylammonium) propyl] ethylenediamine (4C12AC) was synthesized by the ring-opening reaction with epichlorohydrin and ethylenediamine, then by the quaternization reaction with dodecyldimethylamine. The surface tension measurements of 4C12AC give low critical micelle concentrations (cmc), great efficiency in lowering the surface tension, and strong adsorption at air/water interface. The adsorption and corrosion inhibition of 4C12AC on the N-80 steel surface in 20% HCl solution were studied using the weight loss, electrochemical polarization at 25°C. The results indicate that 4C12AC as a mixed-type inhibitor has good inhibition effect on corrosion process, and increasing inhibition efficiency with the increase of the concentration of 4C12AC.
